Some interesting results in these vids.
Yep, I was surprised 5.45x39 was the only round to penetrate the 3 1/2 foot tree. Definitely expected better penetration from 7.62x51.
I think the 5.45 did so well simply because the long slim bullet would tend to slide between the wood fibers, and the velocity was high enough to penetrate but not high enough to cause extreme deformation. And as Mac said, it was barely penetrating. A different loading in 5.45 and 5.56 might well have reversed the results. The .308 is puzzling though, I would have bet money the .308 would have smashed through but apparently the larger diameter, probably coupled with deformation, was limiting penetration. Like trying to jam an icepick through a piece of wood, versus a 3/8 inch sharpened steel rod.
That is what I thought too, the slim bullet of the 5.45x39 because of its smaller diameter was able to slip through the wood better.
Yeah, kinda kills the "I want 7.62X39 cause it penetrates obstacles better than 5.45" argument.
5.45 is a bad ass little round... still cheap to shoot too!
tagging this to watch em all tonite on the highspeed.
Hate takes LESS energy & thought... Dont be so Lazy.
Building or Bitching? which are you here to do?
YES, i work for TEC Tactical. 02/07 SOT
Just knew there was a reason I liked AK74's!
Moral of the story.....its how hard that trees core is, and the type of tree. Let's try Mahogany or Ipe. I think pine is softer so they all would go through, Oak like the video....50/50. Rounds like a needle are engineered to go through Russian trees and pass their tests. Joking.
