Have an old tikka m55 my uncle gave me, realizing the extractor spring needed replacing I attempted to remove the extractor. The plunger wouldn't move so I soaked it in penetrating oil for 24 hours and finally got the plunger to move and got the extractor off but now the plunger is stuck down. Was wondering if it's a good idea to heat the bolt up and try to pull it out with a magnet or if heating the bolt is a bad idea. Only other option I see is to drill it out. Thanks in advance
