Mike NJ,
My Blackpowder friend from Kittery trading post told me to try this cause I was having the same problem.
First loose powder is more consistant then pellets. then the Key to accuracy is in the way you load the bullet or the type you shoot. As for loading when seating the Sabot it is very hard to determine if you have done any alterations to the design with the ram rod, which will make it fly eractilly. With ball and patch it was difficult to keep the patch centered causing it to fly astray. The most accurate projectile I have found is the PowerBelt Bullets. 125 yard shots and 1 1/2 groups I like it. They have special accessories for the ram rod and starter to help keep the deformation to a minumum insuring better accuracy ... works for me Check them out @ www.PowerBeltBullets.com

I guess the best thing to do is keep trying diffeent projectiles till you find one that shoots best in your Thompson.
