LIMIT 2 PER HOUSEHOLD - TulAmmo is converting from a Bimetal Jacketed projectile to a Zinc Coated projectile. Zinc coating is a chemical method of surface treatment (galvanizing) which gives the bullet jacket a more uniform and consistent protective layer than that of machine-stamped bimetal bullet jackets. Thanks to this, cartridges with zinc-coated bullets provide up to 10-15% better shooting accuracy than cartridges with bimetal bullets.
