Finally after a couple years playing around reloading for my hunting rifles, I want to start reloading for my revolvers. So my Hornady book said to use Winchester WLRs or WLRMs. I don't have many of that flavor but literally have 10K of Fed 210s & 215s. Would I be able to substitute the Feds in place of the Winchesters in a 460 mag pistol? I wonder why they always seem to use the Winchester primers in revolvers?
