Has anyone modified a mold with clay,plaster of Paris,etc.?
I'm interested in making a couple of heavy weight full wadcutter molds for a 45Colt and 45/70
revolvers[Redhawk[long chamber allows 1.800"o.a.l.] and BFR respectively]. A 300+gr full wadcutter for the Redhawk and a >=400gr full wadcutter for the 45/70,even at modest velocities with wheelweights, ought to really ruin a critter's day within ~60 yards.
Thanks.
