Best .22 cast bullet shooter

I'm just looking into making a swaging press for airgun slugs.

It seems that the lack of standards and use of chokes in airguns makes the diameter of the slug critical to match to the specific barrel.

Airgun slugs don't have a cartridge to align them to the bore and rely on the magazine for accurate feeding. Tolerances on the magazine as well as the shape, and length of the slug will affect how well/consistently the slug meets the rifling.

I do a lot of non-critical lead casting (fishing stuff) but suspect that cast slugs might need custom sizing to suit a specific bore for best accuracy.

Just a couple of thoughts. Please keep us posted with with your progress.

Cheers!
