Bullet Not Feeding Properly

[geraldhawaii]

I have just put together a 7 mm PRC build. Proof Reserach Barrel, Lone Peak Fuzion Ti action. Hawkins Hunter Bottome Metal, with the Long Action Magazine. Trigger Tech Trigger. Pure Precision Stock.

Problem: When there is only one bullet in the mag, it almost always jams with the bullet tip going downwards. If the mag has 3 bullets in it, the first 2 feed smoothly. There is a lot of play where the magazine can be jiggled quite a bit while it is in the bottom metal. If I hold the magazine up from the bottom, the single round will feed. Put washers between the bottom metal and stock, and it didn't make any difference. I have attached some photo's and video. I would welcome any suggestions.

Hard to say without the gun in hand but… If you look at the 2nd photo, you can see that the cartridge does not contact the feed lips evenly. It "noses down". Likely the reason why rounds 1&2 of 3 feed properly is that there is enough spring pressure with 2-3 rounds in the magazine to overcome the problem. You can correct this by bending the follower spring so that the case contacts the entire feed lip surface. A little bend goes a long way. I'd try that before messing with the distance between the bottom metal and the receiver.
