It's a nice BP rifle.
However, removing the breech plug after the rifle has been scoped, is a real pain in the butt! You only have enough clearance to turn the wrench about 1/8th of a turn before you have to re-set the wrench. So, my solution is, after I have burned alot of rounds sighting it in, I pull and clean the breech plug thoroughly, but never pull it again unless I have to sight in again. My brother has not pulled his in 4 years, but never has a problem with misfires. He just dumps alot of solvent down the bore when he is cleaning the rifle, and lets it drip out of of the plug hole for a long time.
You will hear alot about how bad the ram rod is, that comes with the rifle. The key is, keep it in its compact position when seating the bullet in the bore, and also when starting the bullet down the bore. Only open the rod up (telescope it out) for the final ramming down the bore. It works fine.
Personally, I use a big utility ram rod, with a T handle, for loading all of my bp guns while sighting in, or practicing from the bench. I also use it for loading the first round when I go out hunting. I only use the carry rod of the rifle if I have to reload out in the field while hunting, which is very rare.
By the way, the Huntsman is really well balanced. I think you will really like it. A lot of gun for the money!
Personally, I use a heavy .45 caliber slug, in a plastic sabot, and only shoot about 70 grains of Goex. It really loads easily, is accurate, and shoots with mild recoil, and I believe that I have the functional equivalent of a .45-70 rifle. Fine for deer out to 150 yards. Don't fall into the "he-man" trap of thinking you have to shoot 90 and 100 grain loads. You absolutely don't.
Also, I like to use hollow points for hunting, because if I don't shoot the rifle, then the rifle is very easy to unload (without removing the breech plug), by just putting a worm on your ramrod, pulling the bullet, and shaking the powder out of the muzzle end. Most times, I will then fire a cap, to flare out (ignite) any powder residue that may still be down in the barrel, and run two quick wet patches of BP solvent down the muzzle. I've never had any problems. (It sure beats "shooting a tree" at the end of the day.)
