Re: Hornady Ammunition Safe for your Rifle?

Hey Fellas, please correct me if I am wrong, but isn't that the reason to put the copper coating over the steel jackets to act as a lubricant ( for want of a better word) or a barrier to prevent steel against steel. Doesn't your barrel wear out eventually anyway? I realise that using steel jackets may wear it out quicker as metal against metal without lubrication of some sort has to be a bad thing. Bit like running your car without oil, won't run for long
But I am with you NitroX , stick with the Woodleighs and only use steel jacketed projectiles when absolutely necessary
Yes BB416 you are correct, most if not all steel jacketed bullets will have a coating on them. Silver coloured Norma steel jacket bullets, similar to the RWS bullets shown in the photo above, are coated in tombac a high copper content brass alloy. Some 404 ammo loaded by Norma and sold under the Parker Hale banner have copper coated/coloured steel solids.
Closely examining the sectioned RWS bullet in the photo one can see this coating applied to the inside of the jacket as well. Recovered bullets show a copper colouring where the rifling has scored the jacket.
