Welcome to the forum. It sounds like you are on the right path. There are many people here that can help you out alot. You have what you need the only advice i can give is go out and shoot. Shoot alot. If the sabots are really hard to get down your barrel you might have to try some other sabots like harvester crush rib ( my personal favorite.) If you have the money and time try to shoot as many differnt sabots, powder loads and primers as you can. My cva kodiak .45 is kinda picky. It shoots powerbelts better than any other bulets I have tried.
