Steve it is hard for anyone to guess how well the rifle will shoot. A friend of mine shoots that exact rifle. He shoots a Lyman Maxi Ball with very good accuracy. I can not remember him shooting sabots though. Whether that rifle will shoot sabots.. who really knows. I do believe there are barrels that can be purchased for that rifle. If the price is right, you might want to buy it for an investment in the future as they have really went up in price. Besides, you can never have enough rifles.
