Would this be something i can set when i reassemble it?
Or is this a case of extractor needs to be modified?

I'll measure then, they had only been fired/reloaded once, had not measured them previously, was planning to do that on the second reload.
They are all from the same batch of factory Fiocchi.. I do't pickup other brass.

I'll look into it, but i don't think there's much carbon in there, it's been cleaned with brake cleaner before, but i'll check.

About 700 Factory Fiocchi ball + around (600) softer reloads

How long should a spring last, and do you know what number Wolfs Spring goes in a PM7/45?


I did notice that the reloads with AA#7 seemed to make it dirtier then the Factory or VV N340 loads.. I was planning to discontinue the use of AA#7.. for this and other reasons (small flake, doesn't flow well in the power meter, the power also shakes out of the shells to easy on the 650, i generally don't like the AA7)


Thanks for all the tips Guys, i'm learning things here, much appreciated!
