When I first started shooting my 110, sometimes the bolt would slide over the top of the round in the mag thereby failing to feed. I have blamed that on the magazines not functioning properly. Now I`m not so sure. I have not experienced this in quite a while now. I`ve developed the habit of making sure that the bolt travels completely to the top of its throw qnd then remaining there when sliding forward to engage the next round. Could this have been the solution? Could it be better " broken in " magazines? Both? Anyone else have experience with this? Thanks.
