All I own by means of a rifle is a 22-250. I shot two deer with it last year. 1 went about 10-20 yards and keeled over rather quickly. The other, well I never found her. I was using fusion ammo which I thought grouped pretty well but, I wasn't impressed with construction of the bullet. I bought a box of 60gr federal partitions after I lost my deer. I really wanted to use these bullets but, I could not get a consistent group with them. I am shooting an Icon precision hunter. I believe the barrel is 22" and it has a 1 in 14 twist. I can group 55gr bullets pretty good. I can't find any 55gr partitions though. If I am not able to afford a larger caliber rifle by deer season I really need to find a good hunting bullet. Any suggestions?
