Some 1 in 48" twist rifles will shoot them better than others. But if you limit the bullet to one of medium length and weight of about 240 grains or so, then that will increase the chances that it will shoot well.
Even a .45 caliber pure lead conical like the TC Maxi Hunter will shoot fairly well with a .50 caliber sabot. Just about to the same point of impact as a patched round ball at 50 yards and beyond, although it does need a stout powder charge.
