BTW, I really like the new lineup with the three of you. You two guys are good, but the addition of Chad's hair really elevates the production.
For real haha
Nah he looks cooler with short hair
Lmao
@@uuuultra nah dude the really long hair he is rocking today looks amazing!
I know you barely scratched the surface on this topic. I can't speak for everyone, but I, for one would like to see more in depth videos on this. This satisfies the geek in me, but this kind of info could save some very serious injury. Keep up the great work guys.
Yes please. I come to IV8888 for really nerdy technical details about guns and ammo.
Every time you fire a round, the cartridge is attempting to explode in your face, but the chamber prevents this from happening. As pressure builds after you have ignited the primer, the brass is stretching. Too much stretch (I.e. cartridge is undersized) and instead of using the pressure to send the projectile down the barrel, the pressure escapes by stretching the brass so far it breaks. Not good. On the other hand, too tight of a chamber doesn’t allow you to close the bolt. Not good. Headspace is the sweet spot that allows you to both close the bolt and safely fire the cartridge. Headspace in a nutshell.
if you close the bolt is there an issue?
9 comments , 5 about chads hair...
*6
Yes , what’s with the hair 😂. Good video though
I've been itching to comment on his hair for quite some time now, but didn't want to pick on him in case it was something serious. But now that the cat is out of the bag, What happened to you Chad? Did the 80's comme calling?
A real Chad
He looks like me mum...
great info
In regards to 303 British, the chambers weren't built to S.S.A.M.I specifications so the gauges sold in the US give misleading reading it doesn't mean the barrels are dangerous.
yeah the British no go is 74 thousandths and the American S.S.A.M.i is 71 thousandths which can show it out of spec when it is fine
I think Bloke on the Range did a pretty good video highlighting this a while back.
swanie, very true. The forster field gauge is 70 thou. I just commented to Eric on this. The one the Brit armorers used is 74 thou. The chambers are were made deliberately longer on Lee Enfields. I reload more 303 than anything else. I really think it is important to check your LE rifles to see where they are at as far as headspace wear. Sort your brass to each rifle. If your full length sizing keep a good eye on it you will likely only get a few reloads with full length sizing
Chad looks different. Is he in the witness protection program?
Waitress protection program...He he
LOL
Looks like a woman
High temp gun grease on your bolt lugs prevents wear on lugs and the receiver. Great video guys
Really? Interesting! Is there a particular brand that is the go to?
This was very educational for someone who loves collecting and shooting the old wwII rifles. Thanks!
Generally I have a stressful job. Today especially my day was unpleasant. Im very thankful for this channel because its free of anything that further frustrates me at the end of the day. All these years and this is still the best channel on youtube. 2.1 mil subscribers well earned. Thank you for this content.
Nice job on that 303 explanation Chad. Got a lot from that. 👍🏻
"Go" gauges are important for idiot-proofing a firearm. If someone decides they're going to force a cartridge to fit, that can cause excessive chamber pressures.
Chad's hair is in perfect head space.
Guys this is the best video y'all have made that I have watched.
You explained Head Space and what it entails.
Great Video
R.I.P Barry
amen...
There are plenty of tips and tricks you can use to get around headspace issues in rimmed rifles, fireforming combined with the "O-Ring Trick" can preduce brass for a reloader that is safe to shoot all day long.
TheCanadianLanBoy - most people don’t know about that trick. It would be nice of Eric did a video on it.
Getting radically 70s in here man!
In ‘hair’ too! But think that’s what you meant!
Loving the hair Chad! Don't drink the hateraide, let it grow like the mighty oak.
Timothy Soen man bun
@@nativejuicevapors I support that.
Who cares what the men on this channel think women always dig long hair. Tarzan always wins jesus always wins mermaid guy always wins.
@@Apolloneek As an engaged long haired male, I can support this.
The fact that you uploaded this video a day after I was talking about headspace with my buddy is kinda weird.
The best way without a head space gauge to tell if your bolt action has issues is to just simply watch your fired brass casings. If you see the shells start to get marred (on the back where the brand name is) and shows extra shinny or flattened lettering. Is a good sign to go get your rifle checked for head spacing.
In fairness to .303 enfields, other than the p14 fixing excessive headspace is as simple as buying a new bolt head, easier than most rifles
The problem with that is that when you start measuring those bolt heads, you find that, they will vary as much as .005 in length for the same numbered head. Then you get into the relationship between the bolt head thread clocking vs the bolt head actually seating against the face of the bolt. You cannot have a situation where the threads are carrying the thrust load. It ain't just as simple as replacing the bolt head. A lot of these guns will happily close on a field gauge, even having very little use, which is totally unsafe. I have several examples of these rifles, and truthfully, I grew tired of dealing with their headspace issues long ago. They are an interesting historical artifact, but IMO, a wall hanger.
A body at rest stays at rest. A body in motion stays in motion
Horseshack returns. Oooh ooh Mr. Kotter
Newton's First Law: An object in motion will remain in motion unless acted upon by an external force.
Newton's Second Law: Force equals mass times acceleration (F=MA)
Newton's Third Law: For every action, there's an equal but (or and) opposite reaction. This last one is of great interest to us shooters...especially those who think that a handgun has "knockdown" power. Per Newt's 3rd, if your firing a gun with enough "knockdown" power to actually knockdown a man upon impact, then you too would be knocked down with each and every trigger pool. The fact the mere ounces on a pistol affect felt recoil should give you enough of a clue that there's no such thing as knockdown power when talking about pistol rounds. What we should be talking about is "fightstopping" power. Is there a difference between the common pistol rounds with respect to their ability to stop the aggressor with the same number of rounds. For example, does a .45 acp consistently stop aggressors with less rounds, equal rounds, or more rounds, than a 9mm? This is tough to quantify because of the myriad of factors affecting an aggressor's decision (both voluntary or involuntary) to cease their aggression.
Thanks for this video, guys.
Considering how important this topic is, I find it strange that it doesn't come up very often.
An object in motion tends to stay in motion unless acted upon buy an external force. Pascals law is more appropriate. Pressure is equally transmitted upon the walls of an enclosed system which the headspace area is. The more space that is open to this pressure makes it risk prone to failure.
Ever had a chance to read "Hatcher's Notebooks". He took an M1917 Enfield and reamed the chamber ever deeper as he test fired the gun. The only issues he had were insuring that the extractor held the bolt face closely enough to be set off by the firing pin.
Chad is growing his hair so he can be 1980's Paul Harrell for Halloween
"Welcome back, everybody. This is Eric and David here with IraqVeteran8888..."
😝
Pretty much what I thought.
The Michael Knight memorial hairjob. XD
I love these videos. I enjoy shooting guns, but I love figuring out how they work even more. I would love to do classes with the SDI, but one, I'm blind, so that would cause some challenges, 2 I'm married so can't afford it right now, and 3, my wife wouldn't be to happy about it
oh I can completely understand your hesitation at first, but I have been shooting for years now, and when I get a good point of reference (bench for instance) and working on muscle memory (holding the fire arm the same way every time) and astablishing the same firing position every time, I'm actually not a bad shot. Infact, if more people focused on muscle memory, astablishing the same grip and position every time, instead of relying on just sights, I think most people would see a vast improvement in their shooting...also, when ever I handle a fire arm, I am clearly communicating with those around so I know where everybody is, and I insist that anybody who hands me a gun, that it is unloaded with chamber open, so I can inspect and feel the gun myself, and I also keep that same rule when ever I hand off a gun to anybody else.
Eric I want to thank you and Chad for doing what you do. You too have helped me understand firearms and also Foster love for guns that I didn't know I have. As of now, I'm in the process of enrolling at SDI and I can't remember the last time I was just excited about something. Please keep doing what you guys do. I learn so much from you guys
I love that you guys shout out SDI every video! I’m about to finish my second semester from them, and I highly recommend them!
All Finnish rifles were gauged before storage.
If the rifle failed - it was dismantled and used as parts. The barrel went to smelter.
or just find a new bolt head lol
I will revisit this again and again. Thank for doing this.
another thing even just with partial case head seperation/ rupture is that they can cause squibs by dropping the pressure so much that the bullet doesnt get pushed out
thank god i looked in the chamber after getting the case out
different to other squibs there is no unburned powder and there was a boom so you dont expect it
maybe put the gun away and next time you are at the range you ruin it
well i cleared most of the squibs i encountered with low pressure blank cartridges
FYI the Germans and Russians had so called armorer blanks for clearing barrels and testing firing pin potrution
like when ivan tripped and now got 4 inches of mud in the barrel of his Mosin that he cant get out with the cleaning rod
or war time production ammo got really bad and you got a B patrone or incindiary or tracer round in the barrel
well better dont tap that out !!!!!!
but i have to say that mausers are incredibely strong actions I have seen a Mauser (M48) with 4 bullets being squibbed one shot into another and the barrel was still good to shoot after heating it up and tapping the train of interlocked bullets out
Eric wondering if your 303 field gauge is 70 thousands (forster) or 74 thousands. The Brits used a 74 t. versus the forster SAAMI gauge made at 70 thousands. It may not close on the 74. Love the videos on the old military rifles and the technical stuff too. Keep on doing what you guys do.
I've had quite a few AR barrels not headspace, but I've only ever had one that had excessive headspace, the rest were all way to tight and had to be reamed deeper or sent back to the manufacturer. I always run both a go and no-go gauge for that reason. On one LR308 barrel the bolt would not lock on a go gauge but would lock on Remington factory ammo, but not on Federal and some Winchester. So just save yourself the time and trouble and get the go gauge and use it.
I've got long curly hair too Chad, dont let em get to you
I love Peter Brady
This is the best channel on YT
Yeet Cannon
Yikes Cannon when that rim pops off like that
I have learned so much from you guy's truly appreciate all you do.
@Louvre DeWitt Bukater Neuilly EnLay I was actually looking into the man cans. See great minds think alike.
Chad, you have to get rid of that Ronald McDonald perm
It's just begging for some red dye
In Michigan southern region deer hunting regs for pistol cartridge max length is 1.8. Discuss cutting 45/70 cartridge to 1.8 and reloading and used in 45/70 actions.
Chad lookin' like a mad scientist lol
@7:20 I think what you were looking for was every action has an equal and opposite reaction... so when fired the projectile goes forward pushing the cartridge back just as hard and fast!
Eric and Leon Trotsky.😀
Excellent video and nice example caught on camera of excessive headspace. I've been laughed at but I always check my AR builds. I had one fail the no go. All new parts. The company I bought the barrel from did replace it (after some back and forth with customer service and sending the barrel back with bolt for their "guy" to check it). Anyway, great vid!
This could be the best video you have done yet... Thank you for getting this info out there for people.
The Mosin Nagant kinda does have a 3rd locking lug.
Also, I've found out that rim lock isn't an issue because of the interrupter.
Chads hair going strong
That dam shotgun though..... Most bad ass in the industry!!!
"You watch a youtube video on that?"
Eric- "I made the TH-cam video on this"
What a boss flex.. Lol
You can try a never used System 98 and the bolt will have space without a round or headspace gauge in the chamber. It is stopped by the Extractor, if you remove it it has even more space.
Chad's hair is just ridiculous, it looks sentient. XD
Hair is like weapons choice , whatever works for you 😊. PS. Very informative video 👍
Please please please do a video on reloaded brass inspection
have a 1913 BSA Enfield which was sporterized must have tones of ammo through it. No head space problem.
I was beginning to think my 1943 SMLE was the only one that doesn't eat gauges
and some firearms left the factory with generous head space.................because the military prefer their guns not to jam with ammo made under difficult conditions from multiple suppliers. I had this problem with 2 brand new Longbranch, in the grease SMLE rifles......never fired. Easy to fix, I found people in my rifle club that had the larger bolt heads ( they are numbered for different sizes ) and swapped mine out and fixed the issue.
On the topic of head space... where’s the mullet? 😂 😂 😂
Please do more firearms facts videos like this I had my facts wrong about what headspace actually was and this answers exactly what I needed to know thank you
Headspace all my builds. Thanks for the video.
Chad's hair = Hippie 😁
Ok this needs to be said. We need a royal rumble hair showdown... Chad, Brandon Herrera, John Lovell and Mark of Fit'n Fire fame.
303s hs completely different than say a mauser. Most 303s that fail an american HS test are perfectly fine on an actual crown 303 HS guage
Chad has magic hair. It gives him his super powers.
give her room to do her thang
Thank you so much for including the British info.
I have seen guys make a no go gage with an empty case with a few layers of masking tape over the base of the case. Not recommending it, but it is better than nothing.
You guys missed the opprotunity to show how to headspace an AR/AK or any semi auto gun, with the most important rule being DO NOT LET THE BOLT RIDE FOWARD WITH FORCE OMG!
You mean like it does when it's being fired?
@@logan9334 the point that is usually made with this is that it is not good for your chamber and bolt. Since the gauge is a solid piece of steel. I'm not sure of it is an issue.
I mean slamming the gauge in the chamber can damage the gauge or chamber and give you inaccurate results.
@@bones1x285 my bad I misunderstood. I can see that considering it could potentially be longer or shorter than normal and would cause the bolt to slam into the barrel lugs and/or the bolt face
no kidding... I was answering emails on one screen and looked up at the other screen an ALL I SAW WAS HAIR!!
i feel a part 2 to this on how to headspace the mill surps would be good
24:00 Really refreshing to hear a foreigner pronounce a Finnish word correctly for a change. Is the language really do difficult?
Cheers from Finland!
Love you guys, great video, as usual. And with that out of the way...Chad, love that 70s alcoholic truck driver perm! My a**hole alcoholic truck driver stepfather had one just like it. I do not believe that you are in anyway like that, to be clear, I am just talking about the hair. Chad, you are awesome, keep up the great work!
That's a strange subject to bring up in a TH-cam comment...
@@GruntBurger
I know, but the hair reminded reminded me of that dude so much and I felt the need to explain myself and I wanted to ensure that readers were aware that it had nothing to with Chad personally. Besides, we are all friends on this channel, I would hope.
Great topic. Great video. Thanks!
Eric!!! FIX YOUR CROOKED GLASSES FOR THE LOVE OF GOD!!! You’re Fudd’n it up man, pull yourself together.
Remembering Barry and his "HEADSPACE" gun gripe.
Need a more specific explanation. Maybe a close up or diagram of where different types measure from please.
When Chad's hair gets a bit longer he'll be ready to walk on water...
For those who check head space, how often do you actually come across unacceptable head space on new firearms?
I always defined headspace as a location affording a position of relaxation, while still giving her room to work. Chad's hairdo gives one an advantage towards headspace.
I only watch for the hair now.....
Chad got that hair looking like a young Columbo.
Excellent video - Thank you both!
I'm shopping 6.5 Grendel barrels for a DMR type of build and about all I'm seeing is type 2. For that reason that's probably what I'm going to build and buy a barrel and bolt for.
I'm wanting to buy a bolt carrier without the bolt so I can get a barrel and bolt together. I have not been finding bolt carriers without the bolt.
Holy white jerry curl batman
Eric, love this content and want to see more. I would like to see more in regard to black
powder firearms, bullet making, and such.
I used your “pan Lubing” video as a guide for low buck bullet lubing. Keep up the good work.
I thought that Enfields headspace didn’t matter, like blokeontherange said.
Just check my Mauser and it is not ok to shoot! Thanks guys, getting it fixed now... might have saved me from being hurt!
Chad’s hair allows for plenty of headspace.
Ive seen alot of trailerpark girls eat fieldgauges. Allways slip in a headspace gauge.
Chad needs a perm!!!!! Lmbo....
I think this is great information! I think if you were going to dive into this topic you shouldn't have left out throat and muzzle erosion.
Thanks guys for your vast knowledge, glad to see informative vids.
totally should do a refresh video about the Dutch Beaumont.
CA guy wanting to get into reloading. OMG my head hurts bad now. Thanks for the warning.
Every action has a equal and opposite reaction
Great video 👍🏻
More like this please. Awesome stuff.
Should be hair Space Chad lol. 😂😂😂
I learned a lot! I need to get some gages.
Chad grow a man bun like Reid Hendricks
