I am interested in learning to shoot at longer ranges than I am capable of now. I've recently gained access to an area where I will be able to shoot to 400 - 450 yards. Up until now I've only shot at the standard 100 yard range. I've recently purchased a Winchester Model 70 .300 Win Mag and topped it with a 2.5 - 8 scope. I have a couple questions that I hope you can help me with. Number 1) What kind of initial cleaning should I perform on this rifle... specifics to include types of solvents, oils, etc., Number 2) Are there any rifle improvements that I should make prior to even shooting my first round through this rifle? (bedding, trigger work, etc.) Any help is greatly appreciated.
