Last year I related some problems I was having with a Ruger MK II Target Competition slabside model that I bought NIB.

To briefly recap, I am having consistent feeding problems with all ammo, but especially any lead ammo. The only kind of ammo that gives even decent performance is copper-coated, like Winchester Super X and even that stuff hangs up at least once per mag. Anyway, I took the advice of posters from the previous thread and did two things: (1) polished the feed ramp with some metal polish and a Dremel tool, and (2) fed another seveal hundred rounds of Win Super X through it. Now, here's the deal. The the hangups aren't nearly as bad as they were before, and on the rounds that do hangup, the angle of the shaving?? is much less (before, there was a pretty deep gouge in the stuck cartridges). BUT, the problem still persists. In examining the feed ramp, I notice that there is a very slight lip (maybe 1/32") at the top of the feed ramp near the entrance to the chamber. This lip used to be more prominent before I did the polishing and I am theorizing that this little bit left is causing the remaining problems. I am thinking of getting out the Dremel and polishing that last little bit off so that there will be a smooth transition from feed ramp to chamber, but before I do this, i wanted to check with the experts here.
TIA for any advice, and sorry if I was long-winded.
