If your rifle shot 1/2 inch groups and now doesn't I would bet it just needs to be cleaned really well. I wouldn't bed it or anything until you get some really good copper solvent and some carbon solvent. Bore tech makes some good products.
I would bet once you get your barrel really clean it willstart to shoot better.
After you clean it you will need to shoot a few rounds to get the barrel settled down and shooting good again.
We just did this process to my Dads rifle and it went from a 2" spray and pray to a little under an inch with the same loads.
Keep us posted with your findings.
It's hard to tell whether they were the same box or not. I'm an organized chaos kind've guy so, I keep about 4 boxes with me most of the time but I use the first one I grab because they are all the same. But I have shot a couple boxes trying to get it to shoot right.
I will make sure I find some good cleaner, and try it afterwards. I know about giving it 3 fouling rounds after cleaning, but I live in the city (for now) and can't shoot when I want, but I will def. let you know. Oh, and thanks for the help!!!
