Re: new to muzzleloading
There were once a host of "accessory kits" available. I think Traditions may still sell them. The problem is that some come with speed loaders, some came with small flasks, some use No 11 caps, some use flints, some use 209 primers, some use centerfire rifle primers in a carrier and some use only Magnum 209 primers. The myriad of variations made it nearly impossible to put together a proper accessory kit.
There's a host of things you CAN buy, only some of which you NEED. Although there are some things that are definitely nice to have sometimes. Obviously, projectiles and powder. If you shoot loose powder, you will need a measure. Something to keep the powder in, something to keep your ignition primers in, perhaps a capper,
A ball starter, proper ran rod jag for seating the bullet and for cleaning. Cleaning patches, gun oil, Depending on the projectile, a bullet or patch lubricant, A decent gun screwdriver, a pair of pliers, A pouch or jacket to keep it all in.
Incidentally, I do have a 32 cal inline that has the reciever grooves to handle a 22 rf scope. From your first post, I wondered if your gal lucked into one like mine.
Sounds like her father can steer you right on the extras needed for shooting.
