I have a 1917 Eddystone that was sporterized and rechambered to a 300 Mashburn Improved. This was done way back in the fifties by a long gone gunsmith, so no going back to him. The rifle shoots very well but has an issue. I believe he used the original follower that was for the 30-06. It will not hold more then round in the magazine. If you attempt to put three rounds in it when you cycle the bolt they all come out.I'm guessing the larger diameter of the belted cartridge is the problem and not compatible with that follower. Rather then spending money for useless parts that won't fit. I'm wondering if a magnum follower from one of the many companies like Weatherby, Winchester,Remington and so on would fit and work better.Any one ever dealt with this issue, and what did you do to resolve it?
