Primer Question

deacon51 · March 1, 2005, 11:33 PM

I'm trying to reprime 45 LC's with a Lee Loader, but the problem I seem to be having is that once the round is fired my single action will not rotate, or at least not easily, due to the primer being raised above the base of the shell. What am I doing wrong? Help would be greatly appreciated.

What powder are you using? Are you at max load? I have had this happen using max charge of 231 in 357. I believe a max charge of fast powder could be the problem, possibly too much pressure. With slower powders, I have not had this problem.

Yeah sounds like the pressure created by the charge is forcing the primer to back out. One other thing it may be is the brass you are using if it is all the same manufacture it may be the primer pocket is slightly to large. Try some different brass and see if it helps.

Sounds like a pressure issue. Check your load.

Am I correct to guess you are using Unique or something faster? Too fast (not necessarliy too much) and the case will expand and grab the chamber wall before bullet separation/case setback happens. You wind up with pushed out primers. Too fast and too much and you may see the pushed out primer flattened and excessive case stretching.

Straight wall cartridges in a revolver(more headspace) are more prone to this.

The only time I have experienced what you are describing is if I tried to make some "blanks" that only had a primer in the case, they would back out and bind up the cylinder.

What kind of load are you using?

I agree with G56 on this one. An extremely light load or a blank will cause this.
