I recently picked up a Kel Tec P11. I ran about 50 rounds of Federal plinkin' ammo through it, and 20 rounds of Winchester Silvertip 115 grain. The Federal shoots fine, but the Silvertips are all shooting low. About 2 feet low from 50 feet out. I don't think the problem is me, as my buddy was experiencing the same thing. Anyone else have any reports of Silvertips shooting low? I wouldn't expect 84 cents a round ammo to have troupble.
