Do not look back, and grieve over the past, for it is gone;
Do not be troubled about the future, for it has not yet come;
Live life in the present, and make it so beautiful that it will be worth remembering.

it looks nice, I would work on your rifling though as the projectile seems to tumble when I see the hits on the paper. Why not go for small balls?

Well small balls would be conveinient however they're kind of hard to find. Pencil tips are plentiful and cheap. If you know where I could find such miniballs for dirt cheap then I'll consider it.

BTW the rounds in the vid aren't rifled. The rifled round does tumble coming out of the muzzle but it stablizes after a while. I haven't quite determined when though. I usually reserve the fifled rounds for "long range".
