The reason I asked is I figured next time out, I would give some of the .457 423 grain (405 gr mold) all lead flat points and some orange Knight sabots a try in my flintlock. That would be a hoot if it shot them well. Even if it groups anywhere near as good as your New Englander at 50 yards. That would get a definite shot this deer season. So I will load them with 80 grains of Goex 3f. And if that don't work, I will try to duplex the load with some Triple Se7en.
thanks for the post and idea...
