At least the bullet didn't want to stay in there very well. I could send you some 538 gr but they are sized to .448 so they would probably be a little loose in a .45 unless you fouled the barrel good with a couple squib loads. I doubt you could get them to stay in a sabot to shoot them from a 50 cal due to the length
No I think the length would be OK... Doc shoots those 660 grain lead conicals from his 50's all the time in fact he once told me they were his favorites... can you imagine how big a 660 would be. I think the problem would come in the fit into the sabot - they would need to be tight - so you are probably right they would not work.
