Hello all, this is my first post since my introduction, and I hope it's in the right spot. I've got a Savage 10 FCP with the McMillan stock that has about 3000 rnds through it, and it is definitely towards the end of its life. It copper fowls pretty badly now. Admittedly, when I bought the rifle I knew nothing about breaking in a barrel or how to get the most out of my barrel. That being said the rifle shot well, about 1/2 to 1/3 moa on average. But, like I said it copper fowls pretty bad now and I'm looking at my options.
So here's the question. If I buy a stock savage barrel from NSS (my budget is pretty limited), what can I do to help it shoot its best? Will proper barrel break in help to prevent bad copper fowling down the road? Is there anything I can do to get more life out of my current barrel; like JB compound, or having it set back and re chambered?

Thanks for the help!
Mason
