I have 2 Win M70s that I plan to restock. On one of them the front action screw hole threads got messed up. The screw will no longer thread in. I tried the screw from the other M70 and it won't go in either. I tried the 1st action screw in the 2nd M70 and it won't go in there, the screw is slightly messed up. I'm ordering a few sets of action screws. Will I need to have a smith use a thread chaser or go up to the next size screw?
