Recently acquired a Cimarron 7th cavalry revolver and will look to start loading some ammo. I came across some coated lead bullets from Missouri Bullet co in 200 and 255 gr. The warning is to not load these bullets hotter than "cowboy action power factor"...some math To cut out the noise, I load with Accurate #5 and minimum load data pushes velocity over 900 fps...with ACC #5, any loads you use under that powder weight? I really never questioned the low end of the powder ratings, and now I'm wondering aside from a squib, why would it not be ok to drop a grain or two...from 10.5 to 9 for example....anyways, I hear people talk about detonation etc and I just don't see that in a 10-20%reduced load...so, anyone have insight or developed their own loads? Or just load them up to the published numbers and look for lead accumulation...what do you all do, if anything, in situations like this?
