Only works on headshots.. Fmj dosnt expand if you hit em in the chest/sholder just zips right through and forget about a blood trail you'd never get more than a drop. If you don't wanna keep the pelt go balistic tip(nosler,sst,vmax,balistic silvertips) those drop em on the spot but will tear a hide up but if you wanna keep the pelts I like 55gr Winchester PSP dosnt do too much damage but will expand some.
