Grendel as a Universal Infantry Cartridge

[stanc]

It went through and through, as well as fragmenting the block, and I was at 50 yards.

There don't seem to be any problems with a 123gr SST from a 16" barrel at 2450fps.

Of course, there's the possibility that your block had different wall thickness, or was not as tough as Variable's.

This kind of testing isn't on the top of my list, but it is fun.

Yeah, I always enjoyed such testing. If I were able, I'd still be doing it.
