Questions & Answers
Will this Mag also work with Bushmaster .450 rounds and if so, how many rounds will it hold? How many .458 SOCOM rounds will the magazine hold?

I doubt it, I got one for my 50 beowulf and when loaded full, the feed lips at the top start to bend out and the 50 rounds start to get moved in an upward direction instead of straight. Didnt even bother trying it in the gun

Very disappointed by Nada, Verified Owner, December 26, 2025
Was not impressed with this mag. It’s super cheap feeling. If I drop it I’m afraid it will shatter. Loaded it with 20 rounds and it will not lock in to any of my rifles unless the chamber is open or I remove the last round.

Works with 375 SOCOM by Phillip Ferris, Verified Owner, October 26, 2025
I've been having a lot of trouble finding a .375 SOCOM magazine and here we are. It feeds properly and doesn't prohibit cycling. Only problem with it is that it only holds 7 rounds of 458 or 375 SOCOM.
