Hi Geo, reloads are fine... maybe even preferable...but only on working guns... they are not a good benchmark for troubleshooting... Not because they aren't perfect when made by some of the members.. but a very large percentage of us, like me, haven't the skillsets to make them so?? So we must rely on what's commercially available, that give us the best near original dimensions and performance, and most important, consistency... I think most WWB ammo measure 1.160" and that is very close to what is spec'ed... There are others here that can supply more info on that! I think the PMC ammo may be a near perfectly acceptable performance clone.. as is probably S & B, and maybe some others I'm not aware of... If you run 100 rounds thru with no issues.. you are on line for dependability!!! Maybe all mags should be matched to the guns when they perform flawlessly... seems to be a rare thing of beauty when they run like a Swiss watch.. gott'a love them!...
... Best to all, til...lat'r....GT
