I have a 22-243 built on a Savage 110, it has a Mcmillan A-5 stock and a Shilen barrel, sharp shooter trigger about everything I can put on it. This barrel shoots terrible until it is smokin hot. I couldnt find anything that would shoot so I said what the hell I will get rid of all the ammo. So as I shot the last 20 bullets with out stop the group shrank down to 2 group I can cover with a dime all the way from a cold barrel group of about 1 1/2. Anybody have any good Idea about why this would happen. The stock I bought as a uninletted stock and sharp shooter supply did the inlet. I am at a loss, I dont know what I should be looking at.
