Loading a second round on Saturday in order to put down the buck I'd just wounded, my S&W (Howa) 1500 .30-06 would not feed the second round until I jiggled the bolt a couple times. This rifle has done this once or twice in the past. It looks like the 180 gr. Core-Lokt bullets can hang up on the feed ramp due to some small milling marks left on the face of the feed ramp. What's the best way to eliminate this issue?
