I've read that a 300 AI magazine will fit in 338 DBM/chassis and I see the 300WM Bob Sled is also for 338 Lapua so wondering if 338 (non CIP) AI mag will fit in post 2014 AX chassis (LA - 300WM)? Don't have any single stack 338 mags to check/measure but where I'm going with this is maybe a 300 Norma Mag.
