Re: Savage 99 Feeding problem
Assuming you are using .300 Savage cartridges, one thought is that that the follower is dented or somehow messed up at that slot. The trouble is that it is not a simple job to remove the follower to check, and even harder to get the magazine back together again with the proper tension on the follower. I don't think it is a DIY job for anyone without experience with that gun.
I suggest finding a gunsmith with experience on those rifles or, if that is not possible, a good set of instructions on how to dis- and re-assemble them.
