So far I have not had any issues with the original seating die rolling the neck of the case where it expands and then won't just drop into the barrel chamber.
Right now I am shooting bullets that I sized to .309.
But because the bore is close to .311 I am going to start sizing the bullets to .310 or .311.
I resize Boolits that are .312 jacketed bullets down to the size I need or want.
The cast bullets I am loading are cast from a .312 Lee 100 gr mold also.
Those I cast out of Linotype and then Powder Coat them.
The late friend who left me the pistol use to get the 100 gr cast and coated Boolits from me.
I just have not refined or worked up the best load that he used.
But I believe the only powder he used was Unique.
So far loads up to 5.5 gr have worked well.
