Hi Doc, I've measure a few spares, and trimmed about .010" off the offending unit, and it looks correct, we will see how it does at the range... On the barreled receiver that first exhibited the problem with S&B, I believe, suffered from the same situation as your shooter that we re-chambered and set back?.. did that pop holes in the primer or just fail to fire at all?...
I was able to restore some of the lip for the case mouth to stop against, but not sure if it's enough for all commercial cartridges concerned... I will let you know after the next range test with the now shorter FP protrusion?... til...lat'r.....GT....
