Powder additive to eliminate copper fouling

I have 2 containers of it. I haven’t used it enough to swear by it yet but so far it seems to work exactly as he claims in a 270 Win with IMR-4831. I haven’t tried it in my other calibers yet as the powders contain copper fouling inhibitors.

All of his products seem to be successful. I'm using a Tubb's firing pin and spring assembly in my Rem. 700 .338 ultra mag and couldn't be more pleased!

His shipping is spot on too. When you order he gets it to you with a quickness.

I’ve got his HBN kit on the way now. I’m going to try it with my E-Tips and see if it lowers bore pressure/friction.
