Thanks everyone for the nice comments regarding my rig. Been out two weekends in a row working up loads and finally have a load that is working for me. Best powder, bullet and seating length is as follows.
Brass = Lapua 6mm BR Norma, trimmed to 1.557"
Forming Die = Redding Custom made from chamber reamer
Bushing Dies = Redding Competition
Mandrel = K&M .224
Neck Turner = K&M
I ran the brass first through Forming Die, then through FL Sizer to set back the shoulder. After that I ran it through a K&M .224 Mandrel Die to shape the neck and turned them very little, just enough to take the high spots off. Next I ran the brass into my Redding Competition Neck Sizing die using a .246 bushing. Loaded round measures .248 and chamber is .250". Next I sorted all my brass to .010 of a grain and boxed them up
Brass = Lapua
Bullett = Sierra MatchKing 52 gr BTHP
Powder = H322
Charge wgt = 30.6 gr
Primer = CCI BR4
Length = .002 off the lands
Best group was .193" (3-shot Group @ 100 yards)
