You are correct. If you are just hunting get the PA Pellet. If you intend to live the black powder lifestyle get a Kentucky or Hawken.
The PA pellet rifle requires a PAL. He's looking at doing this without a PAL. For him it's not a pioneer life style choice but rather one that will allow him to start shooting either without or before getting his PAL.
Almar, good point on the cleaning rod and cleaning gear.
Black powder fouling draws moisture from the air and it mixes with the salts in the fouling produced when the powder burns. The result is that the guns rust if not cleaned within a few hours to a day after shooting. How long you can get away with depends on the humidity level in your area at the time.
I found that the best tool for cleaning my muzzle loaders is a non spinning shotgun cleaning rod with a nylon bristle brush of the proper caliber. The barrels remove from the stocks fairly easily and you fill the barrel with hot water that has a little liquid laundry detergent in it. The water does the work. The detergent is just to aid in cutting through any oil left by the patch lube. Run the brush down. When you get to the end give the rod handle a twist to angle the fibers so you can reverse the direction for the pull stroke. If you can't twist the bristles they'll lock like a chinese finger puzzle. That's why I'm suggesting a non spinning shot gun cleaning rod over the usual spinning rifle rod.
You'll also want a brass jag of the right caliber and some cleaning patches. Once it's been brushed and rinsed run dry patches down the bore until they come out clean and dry. Then run a patch wetted with Ballistol oil down the bore to coat the metal and protect it as well as cleaning out any last remnants of the fouling. Run Ballistol patches until they come out clean as required.
I tend to leave the Ballistol oil in place and the next time I'm going out shooting I run a single dry patch through the bore the evening before or just before leaving. That way I've got more oil protecting the bore but I clean it away so it can't affect the powder before heading out.
A note too on which oils to use. Black powder fouling has a nasty habit of forming a tough sticky gum like mixture when it meets a lot of regular petroleum based gun oils. Ballistol is one of the very few that is fully compatible with BP fouling left from shooting. So you'll need to find some of this or some other oil that is known to be compatible with BP. Do not take the gun store clerks advice on this. It can really mess up your bore and set you up for a nasty cleaning session.
Similarly the solvent based cleaning products that work so well for smokeless work poorly or not at all on BP fouling. Water is the solvent of choice. It's the ONLY solvent you need. And the Ballistol is also OK for cleaning away BP fouling. Not as good or fast as water but not bad.
Some barrels have a sub sized powder chamber at the breech end which is a little smaller than the regular bore. If you have one of those you'll need a .357 or .40 size brush to clean that portion or you'll need to make up something to get into this smaller section. And pipe cleaners for cleaning out the flash hole. And if it's got a flash hole bushing you'll want to remove that about ever 80 to 100 shots and clean the threads and coat them with a good grease or the copper based anti seize to keep the threads from binding and corroding together.
