I hear ya simonkenton, however, the powder companies, don't want to hear that stuff. In my .54 I use 80 grains with a patched rb (3F as it won't shoot 2F worth a hoot) and 90 grains 3F with a conical, and the recoil is punishing after 3 rounds. Can't see why ya would even want to touch off 150 grains in a shoulder weapon unless your into pain. Just cause it'll hold it don't mean to be shot in it.
Underclocked, thanks for the info on the twist rate, I kind of figured there had to be more to it than just twist rate, depth of the groove has to account for something.
I checked Cabella's web sight and it doesn't even list it, so it must be a new item. Really like the idea of a muzzle loader on the looks and action of a rolling block, with a 209 primer ignition to boot, guess that's why I liked the looks of the TC Scout which is now defunct. RR
