So I had a 6mm Creedmore built on a Tikka action and Proof 7.5 twist barrel. It shoots the factory hornady 108 rounds really well. I am wanting to switch to the 115 DTACs but I am had really bad luck with moly coated bullets years back. It ruined a barrel for me. Yes...I sent it to a competent smith and they even tried to clean it with no real success. Is the Boron Coating worth a shot?
