I'm closing in on a design: 410gr (+- 3gr) Plain Base, 73% Meplat, .460" (+.002") Bore, .450" long Nose, .100" Front Band, .055" Crimp Groove, Tangential Ogive, WW+2% Tin.
I'm standardizing on cases 2.085" - 2.100" long, as that's where the bulk of my stock is. [unless you may suggest otherwise] A fitment test with a commercial 'pill' indicates a .100" Frt. Band is just shy of the rifling. A max. COAL of 2.560" still leaves plenty daylight to eject, so I'm comfortable with that.
How much shorter shall I spec the Nose Length to accommodate the Crimp Groove Bevel?
Is it reasonable to expect good accuracy & repeatability using cases in the range specified, or should I 'tighten' that up?
Thanks & looking forward to my first "customized" boolit mould.
