I am trying to bump the case shoulders back a few thousands to fit a bolt rifle's chamber. Can this be done with Dillon dies? It seems that the case shoulder is not touching the inside of the die when the press is all the way up and the die just touching the shellplate. The die cannot be screwed down any further to bump the shoulder down without the bottom of the die hitting shellplate. Do I need to use a different die? Thanks in advance.

I'm having problems with the spring that is between the two bell cranks on the power charger. The bottom on the spring has a bend that I assume fits in the hole in the bottom bell crank. After loading a few rounds I notice the spring pops out of the hole. Does anyone else have this issue or is there a fix to keep this spring in place? I think the spring just takes up the slack and does not affect the powder drop, but I know it is not right. Thanks for any suggestions.
