I had a Model Seven Predator in 17 Fireball, it's inconsistent groups drove me crazy. I took it to my gunsmith to accurize, you know float, bed, trigger all the good stuff. He said you don't want to float this barrel, it has to touch the stock. He showed me the two tabs inside the forearm that serve as the barrel rest. I was not a believer. I told him the story of poor groups and he said to add a piece of rubber gasket material in the forearm on top of the bedding blocks integral to the composite stock to ensure contact, retorque. I did, groups improved tremendously. It has worked on some other Model Sevens as well. Just sayin'
Remember, they normally wake up hungry, be there to serve them dinner.
