If anyone is wondering, it needs 7.1 surround sound. I have the hyper X cloud 2s, enabling that built in surround sound it has makes the audio play much better. Ironically its currently the only real use I have found for the headphones / Headset, as it usually makes things 10x louder in games.

@@hillwarrior6 yes, I dont know why they did that but its horrible
There's a good story from the Finnish military of a couple of young fellows doing their national service on an island along the southern coast of Finland, they have orders to do rangings on all Russian registry vessels, especially military ones, to make sure that they do not violate Finnish waters.
Well as any soldiers on a tedious watch, they get bored and fed up with having to manually use an optical scope and a recognition book to range their targets so they decide to use their laser rangefinder on a Russian destroyer.
Not long after they do, their Lieutenant kicks their door down and starts yelling at them to turn their damn radio on, as every Finnish position was screaming bloody murder at them to turn their laser off, as the Russians had been threatening to bombard them, as they thought the laser was a targeting laser signaling an imminent attack.
Not a lesson they were likely to forget I reckon.
Wow that could end up real ugly
This is why I like TH-cam comments.
@@kim98677 hard to say, being painted by targeting laser usually mean an ordinance is on the way. Could be a trigger happy captain. Never underestimate the Russians.

Fun fact: The stock on his rifle is a GRS (Grodås Rifle Stocks). It's made in a small village with 1200 inhabitants, in a valley in western Norway called Hornindal. They started small in 2011, and now they've become an international brand!
Cool thanks for the info
Would a lot of their business be for biathlon rifles. I live in Ireland and watch races occasionally and wondered were they hand built specifically for each athlete.
Legit
Them legend.
Had one, took shots at 1000 yards with my T3. Not great for fast shooting though. Probably the most comfortable hunting stock.
This information can cost 2 grand for 4 days in a rifle class.
Thanks for uploading and sharing with the public!
People would actually pay $500/day for a rifle class? Hmmm...
@@psychosneighbor1509 I wouldn't, but if you go on the Gunsight website, it probably gives you class costs...
Really? This was rather basic information not even 30 years ago.
Or you could just pay attention when your high school math teacher was explaining basic trigonometry...
@@psychosneighbor1509 to be fair you don’t just sit in a classroom for four days. Generally courses such as these have an academic portion and the rest is applying principles they’ve been teaching. Look up racing school sometime if you want to see expensive instruction that you could “just look up on the internet instead” lol. 😉
Spending some time one-on-one with an instructor can help correct some invisible bad habits, prepare you for scenarios you hadn’t thought about, and motivate you to grow. I’m fairly experienced with handguns but my last instructor was especially demanding on me. Kept pushing me so I didn’t stay in my comfort zone. It was fun, worth the price.

To clarify: In Scotland that’s what they are used for golf. They are completely repurposed as golfing (or other sports of a similar caliber) tools

mm / mils = m.
Target height in millimetres divided by mils equals distance in metres.
In a previous video the instructor says MRAD are not metric, but also says both MRAD and the metric system are base 10.
This is very handy bit of information. Sure, you can work in whatever units you prefer, but the metric system lends itself to this easily.
In the field, his 15" target becomes my 375mm.
375mm / 3.5mils = 107m, his result from the pocket slide is in yards, 115 yards, which converts to 105m.
375mm / 1.5mils = 250m, his result is 280 yards, or 256m.
375mm / 0.7mils = 535m, his result is 590 yards, or 539m.
Note the pocket slide version is rounded to convenient numbers.
For a 15" target the actual distances are:
3.5mils is 119 yards or 108m.
1.5mils is 277 yards or 254m.
0.7mils is 595 yards or 544m.
One might argue I'm building imprecision into the calculations by converting every 1" to 25mm up front instead of using 25.4mm, but I would counter that with the pocket slide also has imprecision built-in by rounding to convenient numbers. In all fairness, if I were shooting distances where precise calculations become critical, I would be converting by using 25.4mm to the inch.
If an instructor were to say to me a plate is 24" x 24", I hear 600 x 600 (every 4" is 100mm, near enough). Using the same examples through the scope (FFP MRAD reticle) there's only one other calculation to do, whether it's done upstairs, with pen and paper, or with a calculator:
600 / 3.5 = 171m
600 / 1.5 = 400m
600 / 0.7 = 857m
Using 24" and the given three mil values: 190 yards (converts to 174m), 444 yards (406m), and 952 yards (870m).
Lastly, if the target was about 6' in height, that'd be about 1800mm to me.
3.5mils is 514m (actual 522m), but that'll do, at least for that distance.
1.5mils is 1200m, so getting a bit leggy, there.
0.7mils is 2570m... I'd probably take a bus and get a bit closer for that one.
🤤
Now that also is a good bit of info. Thank you for making it rather simple! Old school is always the best!👍😉
@@mjsmith8655 not THE best but it ALWAYS works.
On conversion of inch to metric, use 25.375 mm to an inch.....in other words use 25mm + 1,5%
Your 600 becomes 609 without much hassle and is very close to 609.6!
When dealing with pi (3.14159), calculate with 3 + 15% and you look like a genius doing these calculations in the field (but you're simply being clever).
Lay off the adderall bro!
1:45 I can't fit that in my pack and it's too big to mount on my rifle.
I have had the same issue. The guys looked strangely at me when they saw I had strapped it onto my backpack. Really inconvenient instrument to use in the field.
@@Ulvetann Same. Went shooting for the first time and I figured they were gonna make fun of me for being a noob. Sure enough, they saw me carrying this thing and pointed and laughed uncontrollably.
The target usually don't let me use it on them... rude...
Ah.. F*cking hell my stomach hurts.. Jahaha.

"I'm not going to tech you how to use a rangefinder..."
Proceeds to do one simple equation and breaks out a slide ruler.
"Sick. So I actually only need one of those, a working brain, and two decent eyes then? Why did I pay for this class again?"
You do still need to understand how to read mil-dot and calculate the range. Sometimes you don't have a range card (he's using a Mildot Master), you might need to do it in your head.
@@ChaiSuBin the calculation can be found online though? And another commenter gave the equation and explained vary well
@@ChaiSuBin So mil is not millimetres? Cool, I was so confused as to why he was using metric and imperial in the same sentence.
I think the instructor forgot to mention how the relation between distance and height is inversely linear.
So if a target with a height of 2 markings on the reticle is 100m away, then the same target at a height of 1 marking is 200m away.
Then you only need to find the height-to-distance ratio at one point, and other distances can be found using the reticle itself.
There wasn't even an equation. He just told you to replace your rangefinder by another kind of rangefinder. what a waste of money.
Simple in depth explanations and easy to understand and listen to. Thank You
He says he doesn’t teach to use a range finder because there’s not much to it but
point reticle at known size target pull out cheat sheet and cheat isn’t much either
He briefly mentioned formulas you can use but didn't get into them, maybe it was later in the lesson. The formulas are basic trigonometry, it's a basic right angle triangle with 1 known side and 1 known angle.
1 known side = Object of known size centered on the reticle, divided by 2
1 known angle = Degrees/Minutes/Seconds of the markings on the reticle to the top of the object you're sighting.
Horizontal distance = known side divided by tan(angle)
Either you whip out a cheat sheet or you whip out a calculator. Either way, you're whipping something out. ~_^
Edit: or the mils thing, that works too.
Well you can memorize that sheet but you have to keep the range finder, like learning math only on calculator.
This gentleman is knowledgeable. Thank you.
This is awesome, I always wondered how to use the little marks on the reticle on a rifle. Awesome vid!

The biggest issue with the rangefinder is whenever One spawns in a crate, someone with a PDW takes it first and refuses to use team speak.
This was the most valuable knowledge I ever heard
Marine vet here, just saw this on my feed and had to click and will say love it. I learned on iron sights, could hit t-box at 1000 yards...and then they introduced the Acog...let's just say I took my grandfather right and continued with iron sights out shooting my marines the entire time. Using the skills I was taught on range, windage, elevation and so on
Believe it or not, I found SVD Scope system easiest to use on finding a target's range.
I've been playing ARMA and Squad for awhile and the video game guides never help. Out of everything I've seen, this is the best advice I've gotten in months...
Jesus christ 🤣!
Lol yeah best tutorials for arma sniping are sniper schools
Gamers 🙄! Im one too but .... fucken hell !!!
Agreed ! 4 decades ago I used a duplex ret and subtended via the mag ring on a 16 inch deer chest average for My area then i used a carbide scribe to scratch a mark and range on the mag ring . Worked great at several realistic hunting distance in My area .
Will definitely try this tonight, thanks
I just finished college last year and I hated every second of it but watching this makes me want to go join sniper school 😂

Thank you comrad. This will help my tarkov survival very much.
i love how every instructor have that vocal confirmation of understanding "alright"
I haven't tried looking yet, but where do I get one of those conversion charts
@Log Splitta Or, as he clearly stated in the beginning, get an MOA reticle/ turreted scope. As he said, they both work the same way. Only the tacticool(keyboard commandos) keep saying "MRAD is better...." Charts are available for both. Most hunting scopes are MOA. If you have more than one rifle with scope, stick with one system and become excellent at using that system. They work the same.
Get it on ebay $35
Most american thing ever... Massive gun, holstered side arm even though he is teaching massive american flag in corner of room and patriotic picture frames on wall
only classroom ive ever seen actively protected
Thank you Sir. KISS systems work so well.
Remember to set parallax on scope before milling the target. Out of focus = object appears larger. Also I prefer the reticle "MSR" for milling targets. Works fine if you get some practise.
800 meters with iron sites. if you can not do that........... All respect too my younger brothers. Respect to tec, saved many lives., never abandon old school. God bless you all.
I aint got time fo all that, thats why I hunt with a AK with a drum mag... One is bound to hit eventually 😅

This man is a god! Wish he was with me at DamNeck at designated marksman school back in 2002. External ballistics. Beautiful. All of this makes sense to me as a half ass sniper in the Corps.
So, what is the *FORMULA* to calculate these numbers?
Can't make one of those "simple tables" if I don't know how to calculate those numbers! which make the whole video kind of pointless. :(
Pretty sure this is from a class, so this is just a snippet of it. If you really want the formula then just google how to rangefind with a MIL or MOA reticle. Ain’t that hard to at least search it up
Its just basic triangle calculation. You need to know how far away the dots on your scopes are and you use triangle formula to calculate the distance.
Trigonometry son! Very simple high school stuff to be honest.
You can derive the formula from the variables and results he presented.
Not entirely sure why this was recommended to me after media declared biden winner.
Maybe it's trying to tell me something.

Great, like the kind of humor this Guy has!it woud be greater if it was my own language !!
thank you
Excellent video! I shoot PRS matches and prefer MOA. We might not know all of the distances, but we know the target sizes. I can easily range by zooming into the target and use my reticle to calculate.
Target size in inches × 95.5 ÷ reticle measurement in MOA = distance to target in yards.
The procedure is the same for MRAD, but the multiplier is 27.77 instead of 95.5
Even though most precision shooters are using MRAD, and it seems to be the military standard worldwide, I personally prefer MOA.
I'm just faster with MOA, especially in a situation where I need to make a very quick adjustment, I can round the 95.5 up to 100 to make quicker calculations. It might not be exact, but the vast majority of the time will get me close enough to bang steel with the next shot. And MOA just makes more sense to me in my head.
What do you mean by reticle measurement? I was looking for an answer to the question of; where does the scope power become involved into this equation?
There are three variables. Range, angle, know size of object in view. Have any two, you can calculated the third.
needed this in BF4

I bet his DOPE book, is extensive!
Im an artillery observer and this method can be used on a greater scale, to be more specific I've used it on tanks, and other vehicles, even dismounted men, at multiple kilometers away.
Fun fact, most of Soviet scopes including PSO-1 actually has a sort of small things that you can use for range finding purpose on right side of their reticle.
I thought that was just a well edited thumbnail. Didn't expect a giant physical reticle
i love arma 3 and battlefield longrange fights. i have a good predictions on those but never really tried irl.
This is a good physics exercise. “Zoom”=image size/ real size= image distance/ real distance. This way if you know the distance in the lenses of the scope and the zoom, you can calculate the distance of the object
The title should be, "Making people think their headphones are broken"
This will come in handy ;)
