Have a late 1950 model 81 .300 savage, non removable magazine in pretty good condition. The issue is with the feed. When loading, the cartridges will push the follower down but won’t feed correctly and bind in the magazine side springs. Anyone familiar with this rifle will be aware that the side springs are a nearly 2 flat spring steel with a curve on the top, left and right to retain and forward feed the cartridge. They slide onto the outside of magazine when disassembled or reinstalled. Any thoughts on troubleshooting?
