TY Safari.
No actually the .264 Hornady SST was out of a 6.5x 55, probably 2,600 fps or something close to that.
I also shot that long Hornady 160 RN and it plowed through also, but I expected that. "Wound" channels looked about the same.
Again, I was surprised that the SST which I have never hunted [successfully, lol] with would have that kind of penetration.
Anyway waiting for the TSXs to arrive on Monday.
