I am trying to set up my 12fv 22.250 55grn v-max. When I use the a.o.l. gauge I get 2.470 from base to tip. When I use the comparator with my calipers zero I get 2.086. I am planning to go .040 off the lands to start (2.046). I am a little stumped. I am wondering with the use of the comparator should I forget the base to tip measurements, and use comparator measurements as points of reference? I also plan to use H380 starting at 35grns and work my way up. Any help or comments would be greatly appreciated.
