168's in a 308 don't penetrate as much as you think ?? That's funny
Yeah, it is funny isn't it.
I've used a lot of X varieties on a lot of critters and only watched a small handful of Accubombs used. I have yet to see a pass-through with an Accu-bomb and that includes 300gr 375s shot broadside at bears.
I have personally put quite a few 270gr Xs lengthwise through big bears without catching a single one.
To this day the only X bullets that I have seen fail to fully penetrate were 80gr TTSX in the 25-06 in moose and a deer, lengthwise. I have seen the little things go through a LOT of bone and still get away...
