Long Action feeding Short Cartridges (AICS)

My intent is to use my Terminus Zeus Long Action (QC) with various barrels in order to shoot both short action and long action cartridges (.308, 6.5CM, and .300PRC). This would enable me to save money by using only 1x action and 1x scope, and having the ability to freely change the chassis/barrel combination between a heavy range configuration (MPA chassis + steel .308 barrel) and a lightweight hunting configuration (MDT26 chassis + carbon fiber .300PRC barrel). I know that we have precedent in the military for LA systems running short cartridges (M24), and ideally it would be similar to our Mk 22/MRAD running .300Norma or .308 just by making use of the proper magazines to ensure reliable feeding… I just need help understanding how to best do this on my personal gun making use of AICS compatible folding chassis systems (I prefer these over stocks).

I’m looking for feedback from everyone on:
(1) descriptive feedback from any shooters who have tried theAccurate Mag AICS .308 LA Magazinewith short action rounds (ie whether I will encounter reliable feeding without issue).

(2) any recommendations for which AICS magazines or mag kits I should acquire in order to reliably feed short action cartridges like .308 into a Long Action (Zues) within a modern chassis system (MDT HNT26 + MPA ESR) if the aforementioned Accurate Mags are not ideal.


Amplifying Information:
**I have seen the Barbour Creek videos with James running Hawkins Precision 30-06 magazines to reliably feed short-action 6.5CM into a long action Terminus Zues… but the employees at both Barbour and Hawkins have communicated on the phone that this is only compatible via a stock with bottom metal using the m5 inlet, and my intent is to use chassis rather than stocks (specifically, MPA ESR and MDT HUNT26). MDT said that I would need AICS compatible 3.850 CIP magazines.

**I have read through the forums for months and encountered conflicting information and mixed word on whether or not the Accurate Mag listed above are a reliable, malfunction-free solution… “Islas82” seemingly communicated Initial Success with these accurate mags beginning 29NOV2024, but then Likely Failure due to feeding issues on 02FEB2025.. supposedly even “ rlsmith1 “ had used these accurate mags for short actions into a Long Action as well… if anyone can provide additional updates or new information, I would appreciate it. I would like to hear if anyone has experience with running .308 thru the LA Accurate Mags into the LA Terminus Zues.

*** I saw the thread on magazines being made with a spacer linked by Tyler Kemp, but it seemed unresolved to me and currently unviable for my use case (.308 capability in my Zues LA which has a lightweight .300PRC MDT26 configuration and heavy MPA .308 set up). Please advise if there is another currently viable, well known magazine option for short calibers in long actions… specific to AICS compatibility.

**** Some additional consulted resources so that others know I’ve done extensive research before posting this thread: Thread 1 / Thread 2

Couldn’t find a way to DM/PM some of those individuals, so hope that posting this casts a larger net for potential sources of information with applicable insight/experience. Thank you for your time.
