pretty much any 06 round will do the job. what i used this last season was the remington 125 grain psp. it worked quite well. of course i shot it in the neck so it broke its necki and killed it instantly. that generally works pretty well. i think i may switch to the rem. 150 accutip or something like that. its a btsp with a polymer tip for controled expansion and better accuracy. but i have yet to try them.
