The claw extractor on your Springfield is likely a good share of your problem. If the cartridge can not slip up the bolt face, under the extractor, the nose of the bullet will be high as it wants to enter the chamber. The feed ramp may need to be widened a bit to accommodate the wider, magnum cartridge as will the feed rails which are part of the action. Work slowly, don't use a Dremel tool on the feed rails, use a small 3 corner file. Work slowly. A Dremel with a sanding drum can be used to widen the feed ramp. Work slowly. I use a Dremel with a fine stone to alter the extractor. Work slowly. This is not a job for a novice, as the receiver can be ruined if the the rails and ramp are over cut. If the rails are over cut, the magazine may never 'hold' cartridges again,,,,,,,, and it'd take more work to build 'um up and re-cut them than the cost of the action. It's a Mauser '98 design. Two weeks ago I fixed the same condition/feed problem on a '98. The nose of the bullet was hitting the end of the barrel. In that case, it was all extractor. Real gunsmithing, not 'drop-in and it works. File/grind and try. file/grind and try until it works like it should.
