Bottom metal piece not staying put

[TX mountain hunter]

I picked up a light weight 300 PRC from another member on here a while back. It had many custom parts, but was never bedded. I love the rifle as it shoots 1/4 MOA, however at times this metal piece will pop out of place to where it will not feed, essentially acting as a single shot rifle which is less than ideal hunting, especially in bear country.

Any thoughts on DIY fixes to make this piece stop popping out of place? What is the name for this Specific piece of the bottom metal?

Magazine box

I've always thought it should float ever so slightly but apparently you have too much room. It basically is clamped between the bottom metal and the action.

I've tried wedging some material in between but it looks cruddy and I haven't tested it yet.

82.5 gr of N570 with a 245 EOL rattling around that 6.2 lb rifle probably doesn't help.

Look up what wedgy provided maybe an extended length magazine box would solve your problem and allow you to load longer cartridge overall length if necessary. Time to break out the calipers and do a little measuring.

I had that happening on a Win M70 for years. I finally changed the box magazine and the problem went away.

Thank you for pointing this out. I don't think I understood what he was getting at.

Might be able to shrink the inlet slightly with jb weld or some other bedding material, it looks like the box inlet is just a bit oversized.
The Wyatt box should solve the issue as well just depends on how much money you want to spend.

That's what I was thinking but I figured I'd keep my jb solution to myself haha.

Take some measurements of the box that you have, and then look at what an extended Wyatt box measures . I am willing to bet that you need an extended Wyatt box. But feel free to Jerry rig.
