Pronghorn, when hunting, just use the thinner patches for your second or third shots/follow up shots. If you need a second shot, the game will probably be down, or you will be closer to it, one way or the other, and it won't hurt to give up a little accuracy.
I load my Brown Bess with a tight fitting ball/patch combo, load that into a clean barrel, but then the two balls in my loading block, around my neck are in thinner patches. As you know, when a smoothbore fouls it gets tight REAL fast. (with a tight fitting ball and patch)
Thinking up all kinds of hunting scenarios in my mind, it's hard to imagine ever firing more than three shots, and most likely all you will get is one shot to knock the game down, and possibly another to shoot it again to finish it off...although personally I carry a revolver to do that.
Personally, I think you'll get your best accuracy with the smaller ball and thicker patch...and seems like loading effort would be less with the combo you have now, than with a larger ball and smaller patch. ???
Gotta love that radius-groove rifling. My Jaeger, with a Colerain barrel and that rifling gave me a pleasent suprise first time I shot it...indeed, shot #9, #10, etc. loaded the same as #2.
