Problems Reloading For The 625 In 45acp


I too ran into this problem awhile ago.... this is what I did to isolate the problem

At first I thought it was the moon clips... so

1 When you find a moon clip that will not drop in fully... remove it, de-moon and try each round one at a time in each of the charge holes... If they all drop in it is probably the moon clip... (I had a batch that were out of spec )

2. More probable is you will find that 1 or more of the individual rounds will not fully drop into the charge hole. And here is what I found
a. When using mixed brass fired from semi autos especially those with non-fully supported barrels or slightly over sized chambers can leave a slight bulge at the base... a full length sizing die cannot reach far enough to the rim to prevent the seating problem from occurring in a revolver.(they worked fine in my bottom feeders also)

b. Using a Lee sizing die further exacerbates the problem especially if you do not lube the cases before running them through the die.

c. I had much better luck using a Dillon sizing die with well lubed cases. YMMV

d. 100% of this problem was eliminated by running all my mixed brass through a Case Pro roll sizer and then reloading.... (after roll sizing, either die worked with or without resizing lube)

I used that brass exclusively in my revo's and never had the problem return. Hope this helps.

just my $.02
 
I made one from a piece of PVC tube. Just trimmed one end to leave a nub to engage the rim of the moon clip. Ranch Products makes a tool as well. Also believe someone made a loader/deloader that was available from Dillon and Midway.
