I'm a lifelong lover of firearms, ammunition, ballistics, and accessories. I was a product development engineer at a major ammunition company for nine years where I enjoyed designing and conducting experiments to test performance and safety. Although I no longer work in that industry, I still love to experiment and learn. This channel is my attempt to share those lessons. Thank you for watching.
SK Standard Plus 22LR Temperature Sensitivity
This video documents my experiment to determine the temperature sensitivity of SK Standard Plus 22LR ammunition. I've read opinions where this ammo loses accuracy below 40F so I decided to see for myself.
In case you are wondering about my math skills; I chronographed 50 consecutive rounds per test but I also shot a couple extra 5-round groups for the accuracy tests.

After noticing rectangular-shaped perforations in a target shot at very close range, I conducted a bullet-soft-catch test to verify that portions of the bullet jacket were, in fact, separating from the bullet after exiting the barrel. I believe the rifling is skiving through the jacket plating, possibly in combination with less than optimum jacket-to-core adhesion during plating, resulting in t...

FAL Receiver Shims Improve Accuracy In Your Rifle
I picked up the RAR LRT I’ve been playing with the trigger I’m also a gunsmith I’ve polished the sear and I took the factory spring out clipped if down two coils and then stretched the spring abit which has resulted in a 2lbs trigger that has passed multiple drop tests from over head I also removed the blade safety
Thanks for this. I have a Belgium made and the stock is coming loose from the receiver. i assume this is an easy fix once the bolt carrier is removed but I’ve never stripped this gun. Any words of wisdom?
i cut (3) coils and did some sear engagement work. i got 1.5 LBS , pull-weight..... i'm gonna work on my slip-angle and see if i can make it 1LB. EVEN .
Quiero que ablen en español puro inglés yono entiendo nada
Great machines. I used these grinders at many shops. Lots of them in the Windsor Ontario area, at Tool and Mold shops. These machines are great for grinding relief on any cutter, sharpening bottoms, restoring the ball and so much more.
Es un excelente tutorial, yo tuve un rifle Browning .22 auto igual a ese, y si lo dessrmas y no sabes ajustalo se mueve el cañón y es muy incomodo, para eso es el anillo que tiene para ajustar..!! Ya habia visto un tutorial parecido este es una muy buena clase..!! Gracias por compartir..!! Excelente video ..!!
Any accuracy increase potential in truing up the bolt face to the barrel chamber face, both in spacing and in geometry?
Possibly, but I doubt I could ever accumulate enough data to demonstrate that the modifications you suggest make a statistically significant improvement in this rifle design.
@@dauntlessendeavors1000 Okay cool. I'd found information elsewhere on the M77/17/22 rifle where shimming was used in the bolt to tighten up the headspacing on cartridges, which significantly improved accuracy. A few thousandths here, a few thousandths there. Sometimes its just a game of incremental changes adding up to accuracy. That's all the expensive stuff factories often avoid, to bring customers reduced cost.
The friction inherent in the trigger pivot which is from the roughness of the castings that aren't polished, honed, or shimmed, is what's preventing the sear engagement. I agree, having a trigger that light is not advisable IN THIS CRUDE TRIGGER ASSEMBLY. It's totally fine in a Timney or some other system that's got forged and polished and precise parts in it. This Ruger system can be improved significantly with some file/sanding/cleaning/shimming but that's more in depth than swapping a spring.
I completely agree. If one must have a trigger pull that measures in ounces, I always recommend purchasing a trigger that was DESIGNED to be operated in that weight range. I also don't recommend that the average person disassemble and stone or polish their trigger parts. 8 times out of 10, they will screw it up.
@@dauntlessendeavors1000 Agreed. It takes some mechanical know-how and some good steady fingers to understand how to do that properly.
Great video sir, thanks for this. I ended up cutting 2 coils off the original spring then adjusting it to where the sear would reset after a partial trigger pull. Ended up a little below 3lbs.
A solution looking for a problem....the original flip up sight is great....no need to replace it....unless it fell off and got lost....
Thanks for sharing this video
Great info, thank,s a lot
Interesting, as usual, John. I find it hard to beat CCI Std Vel and a Tikka T1x. I have shot a lot of groups with that combo and that distance. I can't ever recall shooting average groups of .75". An occasional group, yes, but not an average of the groups. They would be closer to .5 - .6" with some in the .3+ range. Always enjoy your content and analysis(deep, but not too deep). JimE
Hi Jim, Thanks for your comments. I don't have tons of experience with current production CCI Std Vel Target; lately I've been mostly sticking to the SK Std Plus. Of course, I'm already planning to test the CCI again next winter. Perhaps it will become my favorite winter load.
Nicely done. Thanks for sharing!
Thank you for putting this up. That exact same edition is on my wish list.
I realise this video is 3yrs old but why are “action” blocks in the stock and not part of the action?
That is a reasonable question. Perhaps I am to blame for the semantics of calling them "action blocks". I don't know Ruger's terminology for them. I can also only guess as to why Ruger designed the RAR this way. Thanks for watching.
Good luck lashing down the dog! 😂
Aha, like you I didn’t wear my cheaters and missed that screw at the back. Great video!
I know it probably wouldn’t matter for a 22 but when you dial indicate the OD of the barrel on your lathe is there a way to use something like an extra long pin gauge that’s actually stuck in the chamber and sticking out a bit, then indicate off that pin instead of the outside of the barrel. Is that a thing when chambering on a centerfire rifle? Thanks.
Hi Shane, Good question and I do think it matters. On the RAR barrel, there is very little straight section ahead of the chamber before the taper begins. I didn’t want to have to chuck on the taper so I went with the absolute minimum setback required to clean up the old chamber with the Bentz reamer. This decision left some of the factory barrel shank so I dialed in the OD to match the shank. After finishing the OD, I dialed in off the remnants of the original chamber before reaming the new chamber. Of course, the reamer is going to follow the old bore, even if it is a little bit off. If I had a fresh barrel blank, I would have dialed it in off the bore and done everything off that chucking.
Hey brother I like this video Sir. I owned this gun now for the past 6yrs. It shoots and works GREAT. I love it! Great review and video Sir. You got yourself a new supporter here. I would appreciate support if possible. Thanks again!!!

These rifles don't shoot well as they come from the factory. I've seen that in person. It's a shame too, because they are such a nice looking rifle. I was at the LGS a few weeks ago, and saw one of these rifles. I was there to pick up a new CZ 457 American, and compared the 2 rifles side by side. I may have even liked the looks of the Springfield 20/20 even better than the CZ. I wished Springfield would re-think the manufacturing processes of this rifle, and focus more on accuracy. This would be a damn beautiful rifle if it shot well. I don't keep rifles that don't shoot well. Also, you should shoot some 10 shot groups. That shows much more about the rifles potential than 5 shots do. All of my 22lr's will shoot 1/2" 5 shots on command, with just about any ammo. Even with cheap Federal Automatch, American Eagle, and Auguila, to name a few. As an example: My CZ American wasn't shooting extremely well when I first got it, but a tiny bit of bedding work, and removing a little wood, where the barrel was riding on the stock, brought the groups down substantially. No messing with action screw torque bs, just simple mechanics and proper foundation. But, if a guy has to remove a barrel, set the chamber back, and then rechamber to tighter specs, that is far outside the capabilities of most guys here. It should also not have to be done to a new rifle off the shelf. Springfield needs to get their act together.
I have a rifle similar to this one but out of nowhere it stopped feeding the ammunition, sometimes it feeds but it doesn't close completely, could it be a spring? and all cleaning is up to date on the equipment, can anyone help me?
Thank you! RSA.
Thanks!
Thank you for a very informative follow up video. I appreciate the finer points of accuracy that you make. I shoot in NC and I have seen the temperature have an effect on 22 lr ammunition. Can't wait to see your experiment on temperature. Thanks again and keep them coming!!
Hi John, i love your video, your expertise is very cool and beautifull. I learn whith you. Sorry for my english i man french Canadian ( Quebec).
Actually, my English isn't very good, either, but I have no excuse. Ha ha. Thank you for the nice compliment.
Another good video John and I respect your expertise and knowledge. Like I commented in the part one, it is very disappointing that Springfield couldn't come up with a better product for the price. I have fondled them may times at my local gun shops and they look and feel great. But at that price, the thing should not only look good but should shoot better right out of the box. There are other brands that are more accurate and a better value. I appreciate your honesty and when I hear words like "good enough" and "acceptable" I think it fits the 2020 Rimfire model. Always enjoy your content and knowledge. Keep 'um comin'. JimE
Hi Jim, Thanks a lot for watching and for the nice compliment. I do hope that SA steps up their game because I think a lot of potential customers are counting on it and want them to succeed.
@@dauntlessendeavors1000 "...I think a lot of potential customers are counting on it and want them to succeed." And I am one of them. Thanks again. JimE
You may as well give that barrel a good lapping too before you do the next video.
Thank you for sharing this rare expertise. Working on a similar vintage rifle that I learned to shoot with in the early 80s and now understand how to bring back into required tolerances.
Nice work 🎩
Great video, I always love to learn something new. I didn't now that about 22lr's ammo.
Thank you. My new Browning SA had a slight wiggle. Now I know how to fix it. Thanks.
Does the 63 shoot rim fire or center fire 22s?
I've got the same issue with the same lot of ammo shooting through three different factory Glock barrels.
I have the compact with over ten thousand rounds and the safety eventually begin flopping around so i removed it, other than having the back sight insert that's adjustable come loose and fly off it's been great and has been super reliable with everything I've thrown at it. No issues without the safety and I've run this thing hard since the day I got it.
Once again, this channel is a combination of learning, integrity, and wisdom. While I have no interest in .22, I found this video enlightening and I couldn’t agree more.
Wow, thanks again for such a generous compliment! I'm glad you enjoyed the videos.
Thanks for the tighting of the ring
Nice job!
Thanks!
Nicely done!
Hi from South Africa. I aquired a Ex Rhodesian/Zimbabwe FN FAL and it had the same issue. I guessed that it was the hinge pin that was worn, however my local Gunsmith took a look at it to check everything, headspace, bore etc and came to the conclusion that most of the movement was at the hinge pin. He manufactured a shim to fit horizontally that the the hinge pin closed down on and that solve the problem. The hook on the hinge pin had the most wear. I would be very interested in those magnet sims of yours. Regards.
Thanks for your note. I agree that the hinge pin often needs tightening. Unfortunately, I believe they tend to wear "out of round" which is difficult to repair. Aside from oval holes, I think each rifle would require a custom diameter and length, which is why I decided not to attempt making oversized replacement pins.
After watching your other video about the base of the bullet not fully making contact with the rifling on the sporter chambered Ruger, I wonder if this and other sporter chambered rifles would shoot better using a higher velocity/higher pressure .22, (like SK High Velocity, not Stinger) that might expand that bullet base better possibly improving the expansion, thus improving the rifling contact that may improve accuracy.
I've heard velocity is controlled by the amount of primer juice spun into the rim. I don't know for sure. I'll ask my friend at Capstone, he will know.
My 77/22 is at its most accurate with CCI Standard Velocity .22 LR cartridges. It also does very well with Federal Auto Match.
Do you think the model 63 rear sight could be fitted to the 317?
I think so but I'm not positive. I have since sold the 63, so I can't confirm.
Have you ever done any testing to see what the rifle likes? It seems like I here you shooting the same 3 ammo types. A few months ago I tested 20 different 22 lr types in my rar and cz. Cci mini mag was not in the top of the list. Both my rifles shot cci standard velocity and Norma tac 22 very well. In most cases neither rifle liked the expensive stuff. Try shooting a few 5 round groups of each.
Thanks for your comment. When I made this video series, ammo was in very short supply, so I used what I had. I stand by my assertion that an accurate rifle will shoot well with many kinds of ammo and accurate ammo will shoot well in many rifles. I would never take CCI Mini Mags to a bench rest match but I do consider it to be good quality, very reliable, general-purpose 22LR ammo. I think it is much more likely to be used in a rifle like the RAR than say Lapua Center-X and I believe it is good enough to indicate trends of improved accuracy if any of my experiments should actually improve the accuracy of the rifle. Thanks again for watching.
