Hello, I have about a 5 year old 700 Santro in a 300 rum. I'm in my 20's and I dont Know a lot about what I can do to fix my 700. I will take it out to the range and one day it shoots great. Then the next day, it won't shoot a group to save my life. I have checked all of the things that I Know to check. My rings and mounts are tight. My shells are the same. I have scoped the inside of the barrel and it looks to me, to be in good shape. I have also went threw two different scopes, that are both good Burris scopes from what I think might be because of the recoil but I'm not sure. Any help on what I should do would be great!
