How do you make your own 22 ammo?
do you need a license?
Its pretty complicated since they are rim fire rounds. Even if you have empty shells its difficult and dangerous to refill them in DIY fashion. Just buy some - they are cheap anyway.
I'd suggest a bloody good manual, at the least.
it is better if you just buy some bc the bullet are lead they will get really mess up if you doit by hand and more then likely they wont shot righti never tried
