Re: I need help with pressure problems
I would say that you have a short range benchrest type chamber designed for light weigth flat based bullets or a throat that requires neck turned cases.
The chamber most likely has almost no lead. ie a very short throat. I have had the same problem with a 6mmBR that had a short throat cut.
Try a bit lighter bullets of the Berger VLD type with a short bearing surface and secant ogive. Be careful to seat the bullets to be just short of the lands or to just kiss the lands.
If after trying the lighter bullets, it still has pressure problems, take it back to the gunsmith.
