For what ever reason nobody likes the Barnes Sabot. In 3 different of my guns the barnes is #1. I have used power belts in Colorado with good success, due to full bore ammo rule.

My guns are .50s but I think barnes are good in any size.

A note on .45s. Seems for what ever reason to be less forgiveing than 50s, kind of picky about what they shoot. I think it is the speed, many willl disagree but drive a car 55mph then 155 at what speed will little things make the most difference.

When .45 sabots first came out they were tearing up the sabot when shot with three pellets of pyro, causing accuracy problems.
