For brass, how dirty is too dirty?
Still new so bear with me: I figured reloads were just dirtier in general- but I keep seeing folks saying it could be indicative of an issue with your rounds.
All of these are being fired out of a S&W Model 29 6" and a 629 6".
I've been reloading .44
240gr XTP/240gr Berry's plated FP
.44 magnum at 23.5gr H110 with CCI LPP
.44 special at 6gr Unique CCI LPP.
My magnum's have been excellent and dead on accurate. Great ignition. The specials I'm bringing up to 6.5-7gr Unique as I feel they're a bit wimpy, even for specials.
Neither is leaving almost any unburnt powder- but I am getting soot on my cases. It's not a ton, but some cases are dirtier than others. The case mouth often has some soot covering one side, sometimes continuing down to the case head.
I'm having no issues with primers flattening, no case bulging or splitting. Is it normal to just have dirty reloads? What is a telltale sign you're getting improper results?
