I am using new ammo. I don't roll my own and this box has been in use since last summer when I started my fall "sight-in" shooting. I'll try another box/lot. I check scope and mounts often. Probably the first thing I'll check being the most obvious. My bore cleaner has been the Outers Nitro Solvent. "Removes metal fouling & powder residue. Good? No good?

I was reading some stuff on Chuck Hawkes rifle site and a product was mentioned called 'David Tubb's Final Finish System'. Anybody try this stuff? Sounds effective and interesting. The article claimed a significantaccuracy improvement. It basically is a system where you shoot rounds that are provided in order to lap or polish the barrel. The .308 kit used as an example came with 75 rounds in 5 different levels of polish. What a concept!
