The Accurate Mag single-stack, single-feed magazines for the .300 Winchester Magnum are the perfect magazines for any shooter. The .300 WM magazines from Accurate-Mag are built from steel, heat treated, and then coated with a special Teflon for a better finish. For those running the 300 PRC, choose the 3.850 length magazine.

Great mag
Great mag but it required a lot of fitting to accommodate my 7mm PRC so I wouldn’t recommend for this type of build. After saying that I was able to remove material and make this mag work without issues.

Great option for 7 PRC
Quality magazine which feeds great. I had unfortunately bought one of the .300RUM magazines based off an internet search and was having feeding problems. Altus recommended this as an alternative and it was the correct choice.
