sabotloader: I'm using a New Frontier Beartooth (purchased from Cabela's). It's a .50 inline. I didn't get the packaged bullet/sabot combos, but bought a box of .44 cal 300 gr. XTP's. I tried Knight, Hornady and Harvester Sabots - all with the same results - VERY difficult loading. I should probably try a different bullet - perhaps one that is slightly smaller diameter. I don't remember the exact size of the XTP, butI think it's .430. I bought some 295 gr PowerBelts because the season was upon me and I hadn't found anything that would load easily enough for hunting. They loaded great and shot well out to 100 yds (the extent of the range I was on). I am using 2 - 50 gr pyrodex pellets.
I also got some great plains conicals, and they loaded OK - just a little hard to get started.
I guess I don't know which sabots are the thinner ones.

pglasgow: That picture I posted was from Cabela's - I didn't see any PowerBelt 444 gr flat points. All they showed were the lead hollow points, jacketed hollow points (including those with plastic in the cavities) and the dangerous game bullets. I'll have to look again a little closer.
Thanks for the help.
