Roger,
You do bring up an interesting point and know I have a question for the muzzleloading experts.
It is true the Powerbelts are manufactured slightly underbore size. Powerbelt's website says this is due to help in loading. I orginally purchased powerbelt bullets, because that is what CVA recommended. I have never shot anything else and I have never noticed a loose loading. Therefore my question is concerning the size of the sabot bullets.
If the sabot bullets are full caliber size and the Powerbelts are slightly under would that account for the loose loading and therefore lack of accuracy after shooting with the sabots for a long time?I am very accurate with my powerbelts, but would still like to try other loads. However, if this meansI am going to get loose loads and bad accuracy (on Powerbelts) if I shoot sabots for a while then go back to the Powerbelts, then I will stay right where I am.
I hope this makes sense and I can get some opinions from the experts.
