Tri-Flow
I use a penetrating teflon lubricant for my .300 on the exterior and on the bore. It's worked great for me so far, it dosn't dry out and it's had no effect on the inner workings of the barrel, I've cleaned with it and a solution inside my barrel and I've had no trouble. It's cheap and effective, the brand is Tri-Flow.
