|I've got a repro rolling block (Pedersoli) and I'll try Fnuser's method if I get a chance soon just to see what I get.|
|Slimjim, on the South Africa forum they give advice for the Lee Enfield to put a small O-ring on the rim before you use that brass for the first time. This way you push the cartridge to the bolt. |
And afterwards you just necksize and don't need the O-ring anymore.
The minute I did understand why and how, I also understood I'm still not too old to learn.
What works on a .303 British could also be helpfull for a .45 Government?
|Brass is supposed to be elastic enough to expand to the case diameter and then spring back about .0005 to 0015" releasing its hold on the chamber.|
If the remains of the case is still that tight to the wall of the chamber then the brass had pressure on it that exceeded its elastic limit.
To me, that means over pressure - whether you were at the highest listed load or not. I have run into this with my 357 Maximum - and had no more problems after reducing the load 5%.
