AIM projectiles is in Hamilton
Well if you had said .356" I could have helped. But we don't carry what you need, sorry.
i don't know much about cast bullets but doesn't the tok kinda send them out a little fast for a non-jacketed bullet?
Cast bullets work fine for handgun velocities (including Tokarevs and magnum revolvers) so long as they are hard cast and are correctly sized.
The main cause of leading with cast bullets is gas cutting from undersized bullets. Bullets that are too soft for the intended velocity can also cause excessive leading.
