300 prc feed issue

I believe I need to open the lips so the bullet sits "higher". Anybody have an opinions? Accurate mag cip length, cartridge at mag length, xlr chassis and defiance anti action.

I had a similar issue with my .30 LARA a few years ago, and my gunsmith used a home-built tool similar to the one in the videos below.





Good luck!

So it sounds like I'm on the right track. Thank you!

There is nothing unusual about tuning the feed lips on a DBM. They don't always come perfect from the factory so using a simple tool to adjust the width is common.

Enjoy!

Anybody have a DIY tool that they've used? I have a small bench vise that might work. Pliers would work, but it would be hard to get the entire length of the lip even.

Or weld/solder flat lips on a pair of vise grips.

The tools are fairly inexpensive

$15 for the MPA (https://masterpiecearms.com/shop/mpa-mag-feed-lip-adjustment-tool/), but they're currently out.

$22 for AI (https://rcrouserifles.com/product/accuracy-international-magazine-feed-lip-tool/)

$30 for HSP (https://shop.hsprecision.com/product/adjustment-tool/)

If you know any sheet metal or duct work guys, they may have a specialized set of Vise-grips that would work.
