About five years ago I had a Remington 700 built with a shilen chrome moly barrel. I sighted it in and did some load development and put it in the safe since along with several other rifles. This fall I took it out to shoot the same loads and the bolt stuck closed. I got the case out and cleaned the barrel well. Followed with a round of factory ammo to make sure it wasnt the reload and the bolt stuck again. I brought it to the local gunsmith, he bore scoped it and he said the chamber is corroded and the barrel is ruined. The other guns in my safe do not show signs of rust or corrosion. Anyone else ever had anything like this happen?
