I'm not savvy enough to know about the loads but do know that a stuck bullet is definitely something to be careful of.
With a muzzle loader it will be much more obvious than a rifle or any cartridge type gun. Your ram rod will tell you.
You can either pull the bullet with a puller, like a screw type attachment that goes on your ram rod or you can put another charge behind and reset the bullet, (this is important) need to push the bullet back down on the charge and not leave any space, if it had some charge the first round. Sometimes you have to do this a few times to create enough room for powder enough to get the bullet clear.
I've also probably unwisely put my compressor nozzle to the nipple and gave it a blast. It worked and put the bullet through the wall of my garage at that time. Not sure that's recommended and I didn't figure it would work that well but alas it worked and nobody died, always a good thing.
I'm not too familiar with the inlines, if you can access from the rear. Never played with one.
