As I said, I have had an early 625-8 from 9/02 and my early 625JM, another -8, since 2/05, and never experienced sticky rounds. Okay, after I went to a separate seater and crimper in place of the single seater/crimper in my 550B. It seems that as you continue to 'seat' a plated bullet while starting the crimp, you can have the case bunch up (swell) below the 'crimp ring', or where one should be. The separate crimper also has a carbide resizer, forcing the case back to nominal diameter, if need be.
After being chastised for not having any bottom feeders with hi cap mags loaded around the house for Zombie protection, I unloaded a metal .223 ammo box and placed the loaded moonclips around my 625JM for the photo I posted earlier. My revolver-detractor said I could never shoot that many rounds, the box has five layers of twenty-one 'clips, or 105 'clips - 630 rounds. Thirty-five more loaded clips around the house for a total of 840 rounds - plus some HKS 25 speedloaders with .45 ARs. In any case, last Feb-Mar saw me shoot my 625JM as much as possible - over 540 rounds - without cleaning - and without a hiccup. They don't get that dirty shooting clad/plated bullets over Titegroup, anyway.
I would check my ammo re sticking as you load. The .45 ACP should range from .473" mouth to .476" ahead of the rim to .480" at the rim. I've loaded and shot a lot of el-cheapo ammo - Blazers, UMC, Fiocchi, etc. No problems loading - some ftfs with my current hammer spring, thus the Fed-only primers - and Starline brass. As an aside, Fiocchi primer pockets may seem a tad deeper, enough so that light strikes occur. Again, the OEM spring or full-strength Wolff are fine.

PS If you have ftfs, think twice re the C&S 'extended' fp... it's the same size as the OEM, it's travel limiting slot is slightly greater. Without a primer to stop it, ie, like in dry-firing, the fp can travel too far into the pocket, flattening it's return pocket. No thank you. I have a fix, but that's another topic!
