Tim, thanks for the quick reply. I understand your "three-fer" comment now, I think I will order those springs.
No, I was not using the shoulder for headspacing, but it became the dominant headspacing issue with my reload brass since I was not full-length resizing. I am now of the observation, if not firm opinion, that in a break-action the reloads MUST be FL resized to avoid the problem. I have not reloaded for over 25yrs until recently and was trying to get by with only a Lee handheld press, which necksizes just fine but requires too much force, IMHO, for FL resizing. So, I finally got off my lazy duff 3 days ago (first warm weather in central Texas in quite a while!) and mounted my old RCBS benchpress that I have not used since forever, and FL resized that brass and seem to have solved the problem.
I can see your point about not working the brass shoulder any more than required, and even using the shoulder for headspacing if the rimcut is too deep in the breech, but I don't think I have that problem. Is there any other advantage to not fully resizing the case?
It seems to me that the ideal case for this action is a straight-walled rimmed case.... 38-55 and 45-70 come to mind, and this problem would not occur.
thanks again.
