Factory ammo has always been a roll the dice proposition as far as I am concerned! I refuse to allow someone else yo sell me a pig in a polk, if I can't see whats in it and how its assembled I will not discharge anything known to blow up.
I am anal about ammo and loading components. Several years ago as I have only shot hand loaded ammo for over 35 years, including a lot if RF in the past, I have loaded only one handgun brass, and that is Starline! This includes the 327 6" GP-100 I just sold, and had at least 3 loadings on some cases that used max book loads for 100 jacketed bullets in my own cast 136 grain HP ammo, resulting in sub 3" 100 yard groups, no blown cases, and some ready for their 4th loading.
Before I am blasted, these bullets seat no deeper than a 100 grain in the case, so no case capacity infringement, were worked up carefully, and as is obvious shot in the strongest framed gun made for this cartridge besides the FA or hard to find Blackhawk!
My point is I can not express how superior I have found Starline Brass to bve from anything I have used in the past 50 years in a handgun, straight walled case. I have loaded 460 S&W 454 Casull 45 Colt "RUGER ONLY", 38, 357, 32 S&W, 475L, 480R, in every case the stuff is the most uniform with the best brass alloy hardened but not over hardened.
Most of those are with loads I would never post on a forum, but in quality guns and chambers, safe, but prove just how durable this brass is! The other advantage being a reloader is if, which I refuse to believe, the gun had fat chambers that would be the only thing I could imagine the gun could be liable of to create your problem,,,, I would instantly know it the first time I shoved a case thru my Redding sizing die!
Sorry I didn't answer your question, but at 65 years of age I can't stress how much more satisfying, and meaningful your shooting experience becomes when you control the ammo you shoot! Others only think about cost, but every single thing from reliability to accuracy including understanding becomes much more obvious when you become the ammo manufacturer!
You have a great gun,, feed good ammo!!
