MPA 28 Nosler magazine question

[Aviatorfreak]

What magazine will work in a MPA chassis for a 28 Nosler to run 195 bergers. ??

What's your COAL?

Do not know. Have been loading 180 gr in my upper. But am getting ready to buy a mpa chassis and was just wondering the magS work for the nosler in general for the mpa and which ones allow longer load. I think all mpa takes AICS mags

I use the CIP 3.850" .300 RUM Accurate Mags with my 28 Nosler in my Bravo chassis (my MPA doesnt have the 3.850 insert in it right now). The .300WM mags had feeding issues for me. Keep in mind that 3.850" is external length. Internal length would be around 3.77"ish.

gotcha. I’m taking it the 300 rum will for a AICS magwell etc?

 

[Chargerguy]

It's an AICS patern mag. Mfg# 001000043 is the exact one I went with. At the time it was the only mag I could find anywhere.

 

[Chargerguy]

And just to be clear, I have never run that mag in my MPA. Confirming on the MPA site, and with their manual, the chassis can be set up for CIP length mags with the right insert installed. So there should be no issue.
