That @#$%^ 45º transition

[Kurt]

Well here I go again,
I didn't make a reamer for my new .38-50 Hepburn. It was chambered with the DZ reamer and after shooting 60 cornmeal blanks fire forming the cases, blowing the shoulders and necks out with the .30-40 Krag brass to the .38 caliber. I trimmed and reloaded for the final second shot fired with a full load of 3F of the old Goex Express powder I have left and a lead bullet. This did the final expansion of the cases fitting the chamber.
I shot as many rounds as I could without fouling control because it was cold and the fingers were hurting handling wet patches so I just loaded and shot. Pushing a damp patch through when loading got through I found paper rings, no surprise with this happening because of repeated shots fired without wiping.
But what I found is the paper rings will just not only damage a bullet it also can damage a case. Never seen this happen before. The bullet was a deep seated diameter PP to see what the 45 chamber end does to the shank of a bullet.
I guess it's time to get back to the drawing board and make a throated again.
