Weatherby 307 feeding issues

[drake2]

ironworker378,

This entire thread above regarding feeding issues with the Weatherby 307 is specific to 7PRC caliber only because the PMAG® 5 AC L, Magnum – AICS Long Action magazine originally shipped with the rifle in 7PRC was for 300 Win Mag and Magpul does not list 7PRC as a specific caliber that will work with that magazine.

Due to the Magpul magazine design and the short and fat shape of the Hornady 7mm PRC 175gr ELD-X and 180gr ELD-M compared to 300 Win Mag is why there was an issue.

I have not seen anything at all regarding issues for any other caliber other than 7PRC for which the rifle is available.

These mags are designed for belted magnum cases with more taper, so I'm not surprised you're getting nose divies. The feed lips aren't allowing the front the case to rise. My suggestion is to get an accurate 3rd single stage single feed magazine for rum/prc cases and tune the lips. Or take a dremel to feed lips to widen them on the magpul. Also worth a try, see if a hawkins 3rd hunter mag will latch into the bottom metal

Edit, just did some research, it shows on the WBY page, this rifle in 7prc should ship with a MDT steel mag. Apparently they know of the problem and found a solution. Reach out to Wby and they'll prob ship you a free mag.

Send it back. Good thing it's not a month before the opener.

Mine came with a Magpul mag and I bought it a couple weeks ago.

Call Wby and request the new mag, I'm thinking your rifle may been on the shelf prior to the updates.

Just saw these on Bass Pros website, and they list the same thing. The 7PRC only ships now with the MDT..... "Compatible with AICS magazines. Includes 1 Magpul® magazine. 7mm PRC ships with metal MDT magazine." So yes I would call if you havent, ya may get some free mags out of it.

Anyone know of a 3rd mag version for the 7PRC? Something more flush?

Found this thread as I'm considering a Weatherby 307 in 7 PRC... What has everyone's experience been? Accurate?

I wanted a functional 7PRC polymer magazine from the start instead of metal. I have only gotten the 5 round MDT 300WM metal magazine to feed correctly, however the feed lips needed adjusted and were not ideal for 7PRC since it would still scratch the brass during feeding before and after adjusting the feed lips.

MDT now has a 7PRC CIP LA 3 Round Polymer Magazine for sale, so I am going to order one of the magazines to see if it works and feeds better. If anyone else has tried this yet or finds a 5 round polymer magazine that works, please let me know.

Well that was a mistake, need the 3.715" length instead of the CIP 3.850" length so obviously won't fit.

MDT makes a polymer 3 rd for the 7PRC.

I have had mind for just about a year, it shoots the Federal 175 factory ammo great average 5 rd group was right at 3/4 MOA. Consistency with the Hornady ammo (174 and 180) was spotty the 180 shot decently but i was seeing a major variation in velocity and pressure in the 175 precision hunter.

Has anyone successfully used the 300RUM Accurate Mags in a 7PRC?
