I like the Redding competion seater for my 6ppc and was wanting a perfect match for the 220 beggs. Here is what I did to make mine.
I got a 221 fireball comp seater and reamed the sliding sleeve with the beggs reamer. The base to shoulder measurement is fairly close between the fireball and the beggs chamber. I reamed the sleeve until the case protruded the same as my 6ppc seater. ( It cleaned up the old fireball shoulder completely ) The bullet seating stem was to long however. I cut a new snap ring groove .100 lower on the stem and then faced off the old groove.
It works perfect. BTW this was for a .250 neck and I was wanting closer tolerance than what was available.
