Appreciate all of the responses from the shooters that follow the old ways.
A little more on the background of the fellow that told me about sabos and slugs in loose powder muzzle loaders and not doing the job on game.
I guess some would call this fellow a purist. He has the skill of an artist. I have seen his rifles, and I have shot with this man at BP shoots, his rifles are jewel like and are something to behold. He has also become sort of a mentor for me as I want to start building my own smoke pols. The balance of his flint locks are better than any modern center fire as they are all swamped barrels with the exceptin of his Hawkens which are tapered barrels. He has also competed with some of the master builders in the United States and has taken first place. (He is from Northern B.C. Canada) He owns some rock locks that museums have wanted in their collections. When he builds a BP shooter he does it lock, stock, and barrel, not from a kit. This fellow has been shooting flinters, both muskets and rifles, to wheel locks for years. He once bagged a Moose with a Brown Bess using a patch RB at 100 meters . He also builds and shoots Sharps 45/100. I guess he is a bit of an ecentric when it comes to shooting PRB and there ante no other way. When U get to his level U become set in your ways I guess.
I listened to this man respectfuly and offored no counter argument to his theory about slugs and sabos in 1 in 32 twist BP Hawkens. However what he was saying made no sense to me as my 1 in 48 50 cal T/C Hawken shoots 370 grain Maxi balls at 100 meters at a 10 inch gong all day long off hand. (if you clean between shots with holy black)
I am also not a new shooter as I spent 20 years in the US military and 5 years with the USMC in forced recon as a hospital corpsman.
My inventory of center fire big game rifles is extensive. I am finding that when I go out the door I am carrying a Hawken 54 more and more and my center fire guns are regulated to the range or the safe. Is there any cure for this?
