I don't know about a huntsman but, I have got a traditions stainless lightning fire with a 1-32" twist 24 inch barrel. Last fire years I have been shooting the 40/50 180 grain QT, 90 grains 3f pb, musket cap, killed a 7 & 8 point last year killed my biggest 10 pt. year before that, killed a 6 & 8 & 10 point year before that and before that a two 8's a 7 and 6 point, before that year a 3 & two 7's points I guess I have killed a truck load with that bullet. It is an awsome bullet, shots were from 20 to 120 yards. Like I said the biggest one I shot two years ago was right at 100 yards shot him broad side in the shoulder both blades and part of the spine was knocked loose, bullet was hangin out of the oppisite shoulder in skin that was peeled open (pass through?).
