I bought about 150 or 200 once-fired brass in 38 Special at a gun show. I'm now reloading them, and have already processed about 80. I see where there's quite a few brands of brass -- at least four. There's RP, W-W, Sellier and Bellot, and one or two more. Using these brass, I am just loading moderate practice rounds for targets at 25 yds. I have just been reloading these cases "first come" as I pick them up, without regard to case brand. Should this have any adverse effects? Would a person expect any impact on accuracy?
