Just started loading up some 44mags after a number of years. 3 die RCBS set, I first cleaned my brass, sized & deprimed, trimmed to the same case length for a role crimp, primed, belled the case, install powder charge, screwed the seating die to touch the case mouth, then unscrew one full turn, snug down lock ring, seat the bullet to desired OAL . Back out seating stem, lower die to get the crimp needed, screw seating stem down the touch the bullet, lock in position. Now your die will seat & crimp in one stroke. Hope I Helped.
