hi all, I have a hsp sporter stock on my 270 . I recently went to swap it to a 7mm mag. It should fit, even hs says it should fit. But when the barreled action of the 7mm is bolted in, the bolt will not move. When i loosen it to point the bolt will operate, the action flops around in the stock. Hs said to remove some metal from the magazine. Well, before doing so, i bolted the action without the magazine at all, same symptons. Even with out the trigger guard. So it has something to do with the action it self. Worked fine in the 270. The 270 is a few years old and is a sps model. The 7mm mag is a bdl model about 30 years old. Any ideas??
