Bulk Rem 405gr FP with 15gr Trail Boss @ 975fps. My 16" bolt gun likes Rem 405gr with 13.2 Unique @ 1025. I started with 510gr but these are less than half the price. Good for target and gets the job done on the pigs. The suppressor is my Form 1. Not as quiet as my 300 Fire Ball, but does not bother the animals much.
