[QUOTE="Pdvdh, post: 2870771, member: 4191"] This is a second real possibility. The first step to solving the problem is determining where the cases interfere with the chamber. It will typically be 1) the shoulder due to insufficient shoulder setback by the resizing die, or 2) case web diameter interference due to case web expansion ~0.2" - 0.3" forward of the case head, due to a resizing die that's too large in diameter. A chamber that's too large in diameter could also create the case web interference. But that's less likely. We already identified the cure for cause #1, shoulder interference. The cheapest cure for cause #2, case web area interference, will normally be a different resizing die with a smaller base diameter. Firstly, confirm the location of interference, if you haven't already done so. I've used a black felt pen in the past. Close and open the bolt a few times and then examine the case for the interference location / removal of the black coating. [/QUOTE]
