my gun shoots the winchester 100gr power point plus clover leafs at 100yds. they are discontunued now. i've been looking at the win xp3's but haven't gotten my hands on any yet. ballisticly i like the 90 gr rem serria bonded boattails. they have a high BC and good numbers. the 90-95gr bullets seem to have alot better numbers then the 100gr. bullets and you can get them for deer sized game. i wouldn't worry about shooting a deer at 300 with them. the winchers 55gr ballistic silvertips are a bad a** varmint round if your gun can shoot them. i think getting a gun to handle a 55gr and 90-100gr bullet is asking alot with the barrel twist in mind.
