I had the bore measured and have a .381 barrel. Is this going to get interesting to load/cast bullets for? I have a Ideal 265gr GC mold but haven't had time to see how big it drops.Want to use this on deer,bear + moose.Jacketed will do around 3"-3.5" at 100 yards but at .377 are likely rattling down the pipe.The rifling is in G+-VG shape.
