RE: .270 cartridge
The expansion from them out of a 270 is made for deer and similar game. The smaller rounds like 223 and 22-250 are ment for varmints. I shot most of my deer with a 270 or 30-06 using Balistic Silvertips. And one or two with a 243 using Balistic Silvertips. You should not have any problems with them.
