I have a new Optima Pro 50 cal. I shoot 2 50 grain pyrodex pellets and 223 gr CVA powerbelt bullets. When I sighted it in I noticed the first shot with a clean barrel usually flies about 4 inches high and 4 inches left, the 2nd and 3rd I can touch at 100 yards dead center. Then I can clean the barrel and get the same results as before. It was suggested to me that there might be a burr in the barrel and I should take some lapping compound and lap the barrel. I have never heard of this and am looking for some other opinions on what might be the problem. I also have a CVA magbolt 150 that I can shoot 2 inch groups at 100 yards with so I don't think it is me.

Most guns do shoot the first shot out of the group from a clean gun. There are two ways to deal with this
1. Set your sights so the first shot hits the point of impact or center of the group and then after firing at a deer hold 4" low and 4" right for the next ones until you clean the gun again.
2. Fire a fouling shot each time you hunt with the gun and clean it at the end of the day.
you can use J&B Clean Compound on the bore but I don't think it will solve the problem. Most shooter use the fouling shot method in most all rifles from centerfires to muzzleloaders as the preferred method. h.h.

That's muzzleloading. Every gun shoots different. Cleaning and not cleaning between shots makes a difference. I like the heavier bullets.

use a heavier sabot, my optima pro hates the powerbelts with a passion, had good luck with them in the past, but just not with this gun.

I would agree on trying a heavier load. Might try 245g with 80-90g of powder. If you are intent on using 100g of powder you might try a 295 power belt or 300g hornady xtp with sabot.
I have read that it is important not to over power a power belt.

Set your sights to zero for "clean and cold". You don't want any fouling setting in your barrel for any amount of time, even in a stainless barrel. They are called stainless and not stain-free for a reason. Fouling allowed to remain in the barrel for the duration of a damp day in the woods will let rust get a running start on your bore. Your "jump" in point of impact seems very extreme to me. Most muzzleloaders I have shot only had about an inch to 2 inch difference in clean vs. fouled shooting. You may want to experiment around with different powders/bullets to find a combination that does not give such a large difference in point of impact if you have not already tried it. Good luck!
