What range are you going to be shooting the most? A ballistic tip or JHP is good beyond 100 yards, hole in, no exit. But under 100 yards it really tears them up alot of times. PSP's (pointed soft point) are more consistant. They don't blow a big exit hole with closer shots but you also get alot more exits above 100 yards.
I use Win 45 grain varmint packs but most of my shots are now under 100 yards so I'm thinking of changing to Rem 55gr PSP's.
