Over and out
"Contrary to what many believe, standard FMJ, including 62 gr M855/SS109 FMJ, is also not very good against glass."
Regarding M855 AP
I've shot through glass, all sorts of different widths of plate steel and cast no problem. I'm not saying its better than M995/3; but it does penatrate glass easily
I don't know what to think about this comment.
Just about anything will penetrate glass. What it does after is the important part.
exactly.. a .22lr will penetrate even most windshield glass, on the first shot, if you hit it at the right angle.. and most definitely on the second shot.
it's the terminal ballistics we're interested in.. intermediate barrier penetration is only a topic of discussion by how it effects terminal ballistics.
after exiting the glass, how has the trajectory changed? will be be consistent? more questions that matter only in relation to getting to the important part- term ballistics.
if a round's completely deformed/destroyed, a sapped of most of it's energy, it's not going to perform once it gets to it's intended backstop.
Any idea how the MK318 62gr stacks up? Supposed to be a better penetrator, but it's only what I've read:

What ever happened to the troops that could handle the recoil of a 1903 A3 in 30-06?
