Hi Andrew and Thank you for your reply. Im using old roofing flashing and fluxing with a commercial flux to cast my bullets.
The 575213 mold i have you can deform the skirt and easily scratch a groove into them with your finger nail so think we are
ok there. Steve sent me some of his bullets that work fine in his gun and these also tumbled in mine so although Iv never
heard of progressive depth rifling i will will do some homework on that point, my rifling is certainly very shallow at the muzzle
end.
Plan of action is;
a; Stick to TS2 powder till problem sorted.
b; Use a drop tube so as not to let powder get stuck on the crud from the previous shot.
c; Start using a bees wax / tallow mix lube instead of wonderlube.

Best Wishes for a Happy New Year, Tim
