My tipped 'X' experience is limited to two mule deer (MRX) and two antelope (TTSX). One antelope went about 25 yards (.257 Roberts/100g TTSX, the rest went straight down. (.308 Win/168g TTSX/antelope, .300WM/180g MRX/two mulies). No bullets recovered, even with stem-to-stern mulie penetration.

My son-in-law also dropped an antelope straight down with a .30-06/168g TTSX. That bullet also exited.

From what I have seen, expansion begins very quickly but the bullets penetrate very well afterwards, undoubtedly due to high weight retention and the slightly reduced frontal area of the 'X'. If fragmentation is what you want, these are not the bullets for you.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
