I finished a custom Mauser and had a new barrel installed and the action squared and bolt bent. I bought a kit and glass bedded it into the stock per directions. I loaded up some rounds and went to the range with some handloads and after about 20 various loads the bolt would get tricky to open. There were no signs of over pressure from using near max published data. After cleaning it at home it did the same thing unloaded. What should I look for? Could bedding and then tightening up the action screws cause this by stressing the action? I can't find any areas on the bolt that show wear from binding.
Also, does anyone know if a 0.10 (ten thousandths) shim under the rear scope mount will really raise the point of impact 10 inches at 100 yards? I ran out of elevation adjustment and am still 7 inches low.
