One of the best thing I have ever done to a rifle is change out the stock. I put my Savage in a B&C Medalist and it was such a huge improvement, I will never shoot factory stocks again and I can spot my hits way better because it recoils in a much better manner.
I've had excellent accuracy with the 185 and 210 Bergers but the 210's left a little bit to be desired for game but I'm thinking the 185 may function a little better but I'll have to wait till next season to test on live targets. Find a cheap bullet that shoots well and shoot a lot of them, but have a good hunting bullet loaded and figured out also.
One thing that this site has really helped me to do is take my reloading to the next level, once you start streching it out you start finding weakness in your loading. I found my gun is solid under MOA rifle but once I started getting out past 600yrd weekness in my reloading started showing up.
