do you think I can shoot out a ML barrel?

am I wearing down more rifling with every shot?

Of course you can wear one out, but if you clean it and oil it after each use to prevent corrosion, it would take a long time. Maybe your grandkids will wear it out someday? The high wear part would be the breech plugs flash hole. You may have to replace a plug every 500 to 1000 shots for optimum accuracy, but that is a feature that has been designed into these rifles. It used to be nipples with #11 and musket caps, now it is breech plugs or vent liners with 209 ignition.

There just isn't a one answer fit's all. You have different grades of steel, types of rifling, cleaning methods, cleaning solutions, cleaning rods, gun oils, storing practices, powders, primers, bullets, and several other factors to consider. Conventional wisdom tells us that anytime you introduce a corrosive powder along with heat and pressure to barrel steel, something is happening. You might not be able to see it with the naked eye, but over time with a bore scope, I am sure you could. I just don't worry about it, that is why I have over a dozen rifles and SEVERAL breech plugs, I don't think I could wear them all out in 10 lifetimes.  ;D

Now to answer your question. Yes!

If you are shooting the plastic sabot's I can't see it wearing out in the conventional sense. You will get erosion from powder burning and the wear and tear of cleaning and ramrod abuse at the muzzle. So yes you can wear out a barrel, but with careful maintenance it really ain't that likely, I know I don't have the patience anymore, nor the free time it would take.

Ramrods & cleaning rods ruin the rifling at the muzzle.  The oldtimers had their barrels freshed every year.

Swab between shots , keep her cleaned and oiled and the answer is probably no.Patched roundballs were , and are, known to increase their bore diameters from the burnishing effect of the patch going down bore at high velocity( same principal as a buffing wheel), but as of yet I haven't heard of the same effect with sabots.Corrosion and cleaning rod wear will be the biggest problems.Erosion isn't much of a problem in weapons with breech pressures of 45,000 psi or less and muzzleloader ( smokeless excepted) dont get anywhere near that level.
  One of the reasons I went to muzzleloaders is the practically infinate bore life.Typical centerfire rifles begin to show accuracy loss from 5-7000 rounds and the higher the pressure the quicker the throat goes...My copy of the Confederate Ordnance Manual states he after 25,000 rounds the bore of a rifle musket " showed no noticeable enlargement" Now thats black powder, minieballs and iron barrels. Dont worry about bore life, worry about bore care and you'll be fine.

One of the hunting mags had a good article on barrel burn out month before last (Outdoor Life or Field and Stream). The summary of the article was that barrels do not burn out. Unless you are shooting fully auto or thousands of rounds, it doesn't happen in MODERN firearms.
