I have tried reading about bolt timing but I am not sure about this aspect. I have a Rem 700 which was trued and rebarrelled by a very reputable barrel maker. I have not been able to get the accuracy out of it I think I should. I have noticed that the bolt handle hits the bottom of the action bolt notch on closing. Upon firing the bolt rotates conterclockwise rather violently about 10-15 degrees. Can someone explain to me what normally controls (stops)the bolt rotation on closing the Rem 700 action and should the bolt handle bottom out on the action when doing so? The rifle feeds and extracts just fine. I am just trying to get the accuracy out of it that it think it should. (It is chambered 260 Rem and I'm only getting .3-.4 inch groups at best. Average groupds are running more like 1-1/2 inches ad 100 yards. [This rifle was rebarrelled and trued then installed in a solidly bedded Bell and Carlson Tactical stock with a Jewel trigger.]
