Was at Mountain Moulds' website, and fiddling with the specs just for play mostly, and he has that feature in his program where you can specify a tapered front band if you want to. Looks like it automatically takes the front half of the front band, and taperes it from groove to bore-riding diameter.
My question is, would this tapering of the front band be a likely asset in old milsurps that may not have quite symetrical throats? I just wondered if maybe the taper wouldn't at least minimize any non-concentricity by tending to move the bullet more back toward the center of the bore, but I'm not sure of this because of the simple time factor involved, inertia to be overcome, etc. Geez! All this stuff hurts my head when I start trying to figure it all out!
In general, is it better, odds on, to go with a full diameter front band or a tapered one????
