I have a Swedish Mauser unfired by me. Years ago I had a 'gunsmith' attach a scope mount and add a Bold trigger and a plastic stock. The trigger pin had no side support in the stock and just fell out. I replaced the original stock and bought a stock trigger set (sear, spring, pins) from Numrich with both single stage and two-stage triggers. In case it matters the bolt had also been polished.
Here is the problem. With the bolt cocked and the safety in the vertical position, if the trigger is pulled the cocking piece moves slightly but the safety holds. If the safety is then turned to the left (off) the bolt 'fires'. If the safety is vertical and cocking piece is pulled back slightly after pulling the trigger something seems to catch and the safety can then be turned to the left normally. This happens with both triggers. I disassembled the bolt and all looks okay but what do I know. Any ideas whould be greatly appreciated.
Update - the probem is definitely in the bolt. Pulled the bolt from another rifle and it works as it should. I am wondering if the flat on the cocking piece has been ground down somehow during the polishing process. I will measure after a bit and see. If this is the case can another cocking piece be purchased and slip right in or will it need to be fitted? Any headspace issues with another cocking piece?
Final update - the problem is definitely in the cocking piece. Replaced the piece with another and it works fine. The projecting part on the cocking piece is .224 'tall' while the piece that works is .228. So the .004 was either always missing or removed by the gunsmith. This test apparently answered the fitting question but the headspace question remains.
