calhunter, i believe the problem is from flakes of clays coming from the powder drop and/or crud from the primer pocket, i do not suspect unburnt flakes. i tumble the brass (both colt & acp) until brite and shiney, shake all the corn cobb out, double check and lube with oneshot...if i pay real close attention to the primer seater and clean every 10 or so rounds, all is ok. mind you, the deformation is more cosmetic than problematic, the few suspect cartridges just looks shabby in the box...the only thing i can figure is that some flakes are hanging on the powder funnel and dropping out on the shell plate and then being rotated around to the priming pocket...go figure... wyman

What kind of crud? Powder residue, stuff from the old primer? Do you clean or polish the cases before you reload? By the way I'm just south of you in Camarillo <{POST_SNAPBACK}> some primer crud, sometimes flakes of new power (Clays), and, yes, i do clean and polish cases before reloading. this deformation is slight and does not seem to effect the firing of the cartridge...just looks odd...

advice needed... when reloading .45colt or .45acp my 550b primer installation cup becomes contaminated with fallout from the depriming step...unless i keep a REALLY close eye on the primer pusher, crud will deform the primer... anyone else had this issue??? fixes??? wyman

been reloading 250gr RNFP for my CAS shootin with a tight roll crimp...now i'm getting ready to reload for my new S&W1911, gonna cast lee 228-1r-rn, lube, load in starline brass with 4.3gr Clays and need to know how much if any crimp (taper i would figure) is needed for best results... thanks for any and all advice...
