AICS Long Action 300WM VS Magpul PMAG L Magnum AICS Long Action

It would depend on what long action magazine size your bottom metal or chassis is made for, as to which mags you can run. The PMAG 5 magnum, I believe is made for 3.715 size inlets and also only accepts up to a 3.50" COAL. With a 300 WM, that is a big limitation if your reloading (my handloads are right around 3.69"). Whereas some the other magazine length standards can take longer cartridges. If you plan to only use factory ammo, the magazine cost savings might be worth it to you. Thats the only real benefit I see other than weight savings. I run Accurate mag, CIP length magazines and have been very pleased with them. Once you get past the price, they are very high quality and have functioned 100% reliably with any ammunition I have tried.
Do you know the magazine length size of the Seekins DBM? I wasnt aware that they currently make a long action bottom metal. As far as magazines go, I have not used a wide variety. However I can recommend the Accurate Mags, they offer a lot of different options for different setups. I use their 300WM CIP (3.85") length magazines, 00100-0023.
+1 for Accurate CIP length mags for 300WM!
The KRG X-Ray is CIP length from the factory but I believe you can install a spacer to accept the standard 3.715 length mags.
Accurate Mag offers 3 lengths for 300WM, the most common being 3.715 (smallest) and 3.850 CIP (largest). I have and use both and have never had an issue with an Accurate Mag.
Best of luck with your build!

I just finished load dev with the PMAGS. Max COAL is 3.58”. I am running 208 ELD-Ms at just shy of that to ensure feeding and with a Mk-13 chamber I am .11” off the lands. Accuracy is exceptional.
You would be best to buy the correct size mag for your DBM. Standard AICS DBM length is 3.715" and most likely this is what you'll need. The package should say, or you can measure the opening with a caliper - keeping in mind there will need to be a little wiggle room so your measurement will be greater than 3.715".
If you want to run CIP mags, you need CIP length bottom metal, or a CIP length chassis.
Good luck!
Thanks, I have both mags, and depending on where my load ends up, I'm going with the Pmags first. I'm just preparing, if I end up using the Accurate mags for the longer length, then I guess I will end up getting there DBM? How does there DBM get reviewed? positive or negative?
