Things that were meant to go in rifles most of the time suffer few constraints and as a result can be all sorts of shapes and sizes.

Calibers and the firearms they go in really is a broad topic so this cursory overview is meant more to help you narrow your question if you want to know more.

  This is an old US Army training video on ballistics that might help shed some light on powder burn rate, pressure curve, barrel length, etc. A lot of it isn't relevant to your question but it helps explain why cartridges on the "pistol" end of the spectrum use smaller volumes of faster burning powder and shorter barrels and and cartridges on the "rifle" end of the spectrum use larger volumes of slower burning powder and longer barrels.

If you're interested in old time .mil training videos, archive.org has them all available as high quality downloads. you don't need to stream them, you can make a big collection and stash them with your anime so you have something neat to watch if the internet dies. http://www.zenoswarbirdvideos.com has a lot of the old aircraft training films organized.

Just watched the P51 training video, good stuff.

absolutely solid dump, thank you for your contribution and for leading by example by being a good citizen of /k/

>>107706
glad you enjoyed it

whatever you choose you can certainly do better than diamondback. how about a nice masterpiece arms carbine?

There is a retarded amount of easy money to be had from posting gun pics to IG. They don't all have to be selfies, you can take picture of the guns if you want.

I think my favorite is ridiculous magnum revolver cartridges being fired from absurdly short barrels. Bonus points if the owner actually got a custom carry rig for the fucking thing. Pic is S&W 460ES.

He's probably better of not practicing, otherwise he'll develop the flinch from hell.

>>107721
thanks for getting opchan shut down, faggot

>>107721
How come 7zip refuses to open this?

  >>107724
I'd guess that the original was a PNG (lossless compression) and that there is a jpeg (lossy as fuck)

>>107725
as much as i like jpegs and their trippy artifacts, whoever decided to resave that pic as one is retarded and whoever reposted the image without realizing that it was fucked is is clearly not involved in 3d printing and saved the image for some other use.

Never bought from him. I see the website is still Web 1.0 and looks like a 80yo granny designed it. I am surprised there are no random lens flares.

He does have some cool stock though...might just send him my C&R copy...

Oh this fucking guy.

> E-mail us your order and include your name, address, and the first half of your card number to Email1

> PLEASE DOUBLE-CHECK that the numbers are correct.

> Send another e-mail to me personally at Email2 with the order information, but include only the last half of the card numbers as well as the expiration date and your phone number. This second email address goes directly to an encrypted computer in a room that only I have access to (no one else is allowed in that room at all).

I met and spoke with him a couple months ago at his home office to make a sale to him. He is incredibly friendly and an excellent person to do business with. Very interesting man. I've ordered two rifles from him and have had them the very next day.

Gonna go look at the FN tomorrow, may also look at their SCAR 16.

Another fren was sucking X-95 dick. So not an AR but very interesting in theory. Might like, IDK.

>>107605
I'm a big fan of the SCAR 16. It's a great shooter and the only problems I've ever had with the gun were short stroking when I put the gas regulator on suppressed, and when I managed to jam a round in the chamber backwards while trying to admin unload the gun. (Rolled snake eyes, critical miss.)

A Gesissele Super SCAR trigger is a must and I recommend some kind of rail extension. (PWS or KDG)

But, in reality, I hardly shoot mine anymore after building an AR for competition with an adjustable gas block and lightweight recoiling parts. The SCAR is heavier and has a huge amount of reciprocating mass. It's like the gun just pushes you around. A muzzle brake doesn't help much, since the brake works immediately as you fire, then some milliseconds later the bolt hits the back of the receiver and you get a thump.

Another note about the SCAR, gen 2 pmags do not drop free and need to be modified just slightly to prevent the bolt stop from riding up. Gen 3 pmags work great.

However, if I needed a straight up combat gun to fight space aliens, the SCAR would be my go-to. But if the threat consists of robots, dinosaurs, or robot dinosaurs, I grab the HCAR.

>>107603
Didn't Tromix do that like over a decade ago?

The FN was nice.

Whereas, I like the SCAR, I'm more familiar with the AR/M4 platform.

And the X95 felt oddly natural, and nice and short.

Ah yeah, sorry about that gentlemen. Forgot it's SFW board.

  >>107609
The episode on the Pedersen device is the definitive work on the piece.

For anyone that's new to C&Rsenal, check out the Pedersen device, the BAR, the Lewis gun episodes. They're fantastic.

holy fuck keep gore images out, dang it.

Unlikely, and besides; death is preferable to living under another AWB.

If the AWB returns, we really have nothing else to lose at that point.

Anyways, why are we letting anti-gun shills and lefties shit all over the board?

>>107269
You sure showed him!

lmao someone show this noob the avra valley shoot video

Yeah, I'm sensing some rose tinted glasses. Even if it were that cheap at that time, the dollar doesn't go as far for anything as it did back then. 5 cents per round is absolutely a reasonable price right now.

Meanwhile, where are you getting 50 caliber pellets for less than 22lr prices? Best I'm seeing on them is like 20 cents per.

>>107575

In 2006 I grabbed a bulk deal that was less than 1 cpr. Hardly the norm, though.

For air slugs being less than .22, he has to be talking about casting, which doesn’t take into account time gathering range scrap, smelting cost, tools, and electricity/propane cost. Hardly less than 6 cpr.

In 2008, I typically paid $20 for a 525 round box of Remington Golden Bullets. .22lr is easy to find again in stores in my area, but the price has stayed up at the 8 to 11 cpr range.

>>107575
>>107574
Well, it's been a long time, I think it was actually the 1000rd bricks. Still cheap as fuck.

>>107576
I am talking about casting. I've spent plenty of time casting boolits for muzzleloaders, I don't see my time spent on it as a monetary expense if it's simply supporting my hobby. And tools are one time expenses.

Definitely cheaper than a powder burner.

The original CO2 guns looked good.
