Missouri allows the use of centerfire pistols and revolvers during the Alternative Methods Portion of deer season--that is the normal muzzleloading season. I have thought of carrying a .357 along with my muzzleloader in case I needed a "finisher". That would allow a faster second shot then swabbing and reloading the smoke pole. I would use a 158 grain soft point if I do this, whatever brand that I have. I have a 4 inch Security Six, not really a hunting handgun so I am limited to a very close shot. As above, a .44 mag. would be more suitable, but I do not handle the recoil very well with them.
