Has any found a slug that will properly fit the .30 bully barrel? I've tried the FX .30 slugs and find that there diameter is too small and the tumble. Any help would be greatly appreciated..
Those hatsan .30 are like a .302, or .303 barrel. Much like the Korean guns. Try those dia. I had one .30 Hatsan long ago and it was a hair bigger than a true .30.
