Military Arms Channel on youtube does some pentration test on the 308 Winchester, 7.62×39, 5.45×39 and the 5.56mm.
In the video the tress are said to by 3 feet in diameter. I think that statement is in error. Its probably more like 3 feet in circumference instead of diameter. A simple way to convert circumference to diameter, measure the circumference then divide by 3. If you want to be exact, measure the circumference and then divide by 3.14. For most intents and purposes for this type of video, divide by 3.
I was surprised the 5.45×39 penetrated the tree while the other calibers did not.
What “really” surprised my was the lack of penetration by the 308 Winchester. But then again, shooting from a bullpup the 308 may not have reached terminal velocity. I wonder how the 308 would have done out of a 20 inch or longer barrel, or from a bolt action rifle instead of a semi-automatic.
Why did the 5.45×39 the tree, while the 7.62×39 and the 5.56mm did not?
This video has made me consider adding an AK-74 to my collection. Before I can add an AK-74 to my collection, the panic buying will have to slow down and my wife and I need to get moved to the homestead.
Sturmgewehre has posted another outstanding video on youtube, this time its about the AKS-74U Krinkov.
In 1979, a shortened carbine variant of the AKS-74 was adopted into service with the Soviet Army: the AKS-74U (“U” — Russian: укороченный; Ukorochenniy, or “shortened”), which in terms of tactical deployment, bridges the gap between a submachine gun and an assault rifle. It was intended for use mainly with special forces, airborne infantry, rear-echelon support units and armored vehicle crews. It is still used in these roles, but has been augmented by various submachine guns, and the AK-105. It is also commonly used by law enforcement; for example, each urban police foot patrol is issued at least one.
The rifle’s compact dimensions, compared to the AKS-74, were achieved by using a short 210 mm (8.3 in) barrel (this forced designers to simultaneously reduce the gas piston operating rod to an appropriate length). In order to effectively stabilize projectiles, the barrel’s twist rate was increased from 200 mm (1:8 in) to 160 mm (1:6.3 in). A new gas block was installed at the muzzle end of the barrel with a new conical flash hider combined with a cylindrical muzzle booster, which features an internal expansion chamber that increases the weapon’s reliability. The booster supplies an increased amount of residual gas from the barrel for the gas system. The chrome-lined muzzle booster also burns any remaining propellant thus reducing the gun’s signature. The muzzle device locks into the gas block with a spring-loaded detent and features two notches cut into the flash hider cone, used for disassembly using the supplied cleaning rod. The forward sling loop was relocated to the left side of the carbine and the front sight was integrated into the gas block.
For a SHTF situation
I see the AKS-74U as mainly a truck or boat gun, maybe something to carry around the Bug Out Location.
The problem I have, is that I were to buy another AK style rifle, it would “have” to be an AK47 in 7.62×39. I do not want to have to start all over stockpiling yet “another” caliber.
I already stockpile 22 long rifle, 223, 270, 280, 7.62×39, 30-30 and 308 Winchester. Adding yet another caliber to the mix would further complicate my stockpile.
Besides the stockpiling ammunition issue, what niche does the AK-74 fill? What can the AK-74 do that the AR-15, AK-47 and FN/FAL can not do?
