An unusual torture test of AK and AR platform rifles, a sub-zero(in Fahrenheit) test to see if they'll still function when subjected to such tempatures. It's not a good test. It doesn't test the firearms. It tests the testing procedure (and possibly the shipping condition of the guns). I've soldiered in polar conditions and I could tell you that most military firearms, new and old, function pretty flawlessly in very cold climates. They're engineered to. The only thing is that plastics become more brittle. But the manufacturers obviously have this in hand when they choose plastics, because I've never seen or heard it being a problem. In cold climate, the air has very low absolute humidity. There's extremely little water vapor in the air. That is not the case here. The fridge collects a lot of humid air when it's open. This then condensates and form ice. The guns are then chilled to become very cold and taken out. Then even more humidity condensates on the cold metal and freezes to ice. The AK, which has pretty slack tolerances, becomes filled with condensation ice. In a real cold environment, that would never happen. This ice is then the problem for working the bolt, until it's cleared enough. Then it's not. The AR, which IMO is a more reliable firearm than the AK (if you treat it right), has much better fit and closer tolerances. It doesn't suffer this problem. There is not enough ice buildup to interfere with the action. But the firing pin is stuck or dampened. Why? I very much doubt it's ice. The rifle is probably delivered greased. The fallback principle for guns in cold environment is to wipe the mechanism dry (particularly the firing mechanism) and avoid taking the gun into warm (moist) indoor conditions (to avoid corrosion from condensation). Though you can use very light oil and very thin coat. But the AK's firing pin? Well, I dunno, but the AK was sure affected by rust afterwards. iirc we actually had 3 different types of gun oil for use in different places, the arctic version wasn't even the same type of oil as the temperate and the jungle.... one being a light mineral oil, one being a heavy and the other being something else that didnt freeze unless you went below -60 Celsius (and at that temp everything stops working) of course they did away with one of those things (bother light and heavy mineral oils at the time would freeze solid before you got to -25, which is pretty useless for most arctic operations and given that the majority of the weapons were at or near the sea humidity was still a thing) also note i'm not from the usa...

Vid on what Brush guns are and tests how flat nosed cartridges like .45-70 fare against pointed spitzer cartridges like 5.56 when fired through thick brush. Here's a sequel vid where they test out even more calibers against brush. Paul Harrell did a vid on the subject, trying other various calibers to see how much they do or don't get deflected by brush.

Paul Harrell did a vid on the subject, trying other various calibers to see how much they do or don't get deflected by brush. Good video. I think the most important parameters that dictate how well the projectile will go though stuff without being deflected is spin rate and the thickness of the jacket (or lack thereof if its a lead bullet - if so, its hardness). For example, the .223 has a very thin jacket and with muzzle velocities up to 3300 fp/s extreme centrifugal force exerted to it. So the slightest impact on the jacket will separate (peel) it and make the bullet fragment to some extent, making it super unstable in flight. (And an awesome anti-personnel round) On the other hand, the heavy and slow lead bullet has neither extreme centrifugal forces nor a jacket - but the lead is very soft. A pure lead bullet is so soft you damage it by dropping it from a foot or so on a hard floor. You can chip off flakes with your fingernail. Now imagine a branch smacks that lead projectile with the speed of sound, thats gonna damage it a lot. I think that's why the AK47 round did so well, the 7.62x39 usually have a very thick jacket and the velocity is not so high that the slightest impact will make it fragment or peel its jacket off. I wish he tried out shotgun slugs, proper ones are made of very hard lead alloys, are relatively slow and have no spin.

I wish he tried out shotgun slugs, proper ones are made of very hard lead alloys, are relatively slow and have no spin. Agree, Paul Harrell talks and dress funny (and if you saw my hair style now, you'd tell me to stfu about that), but he really knows what he talks about. Always solid information and good reasoning. Centrifugal forces... Eeh, the peripheral acceleration at the bullet jacket is crazy high, yes. But it doesn't generate high forces. Taking a fairly representative modern AR-15; If the entire bullet weight was focused in one point on the jacket - which it's not - we would maximize the centrifugal force, but it would still only be 39 lbf. As it is, the forces trying to tear apart the bullet is much less, but I can't be bothered right now, so you have to do with my excessive estimate. PS Edit: I bothered: AR-15, 1:9 twist rate, 3210 fps, 55 grain bullet - approximated as a 0.7 in long cylinder. If the internal of the bullet is assumed to have no structural strength at all, you end up with a centrifugal pressure of 279,648 J/m^3, which happens to be the same as Pa, meaning 0.280 MPa, at the surface of the jacket. And in turn compare that to normal atmospheric pressure which is about 0.1 MPa. So no dramatic thing. The entire sum of force on the jacket is only 4.016 lbf.Now contact forces, otoh, between fast bullets and any matter it impacts with, increase very dramatically with velocity. I think a rough guide is that it relates to the cube of the velocity? (or is it ^4 ?) And there you have a lot of it: Why light fast bullets changes direction more easily. Why light fast bullets do more quantitative damage. Why light fast bullets penetrate armor easier, but stops shorter in soft medium. And, of course, why light, fast bullets get more mangled.

if he is sentenced to death it should be an immediate sentence though and not one of these long drawn out affairs... sadly its unlikely that he will be, its far more likely that he will be filed under the insanity defence and relegated to a mental institute for a few years until he's been properly medicated and then let free under the liberal idiocy ideology that you have to save everyone.... clearly Cruz is a feral mutt that needs putting down just like any other feral mutt would be.... and like anything its not the tools that are the problem (even if every bad workman blames them) but the person using them....

Took out my dremel tool and polish paste and worked on the barrel of my CZ. Polished the feed ramp and the chamber mouth to a mirror finish. I cycled some dummy rounds through it and I have to say, that polishing makes all the difference. When I cycle rounds through it feels like I deceased resistance and friction by 30%. If you have a pistol I highly recommend polishing the internals.
