Thats what varmit bullets are meant to do man. Blitzkings, V-Max's, berger varmit,Speer TNT, barnes varmitorsyou usually want them to fragment. they are not deer bullets.

Thats why alot of people who want to protect the pelts use barnes solids. I know where I kill chucks, I wouldn't want a solid skipping of the ground and hitting a house.
