I.ve had about 15 different M-1 Carbines over the years. I still have 2 IBM's, one normal and one with the T-3 Night Scope. I use the RCBS Carbide sizing die, regular dies seem to have some issues with complete length sizing. I've loaded somewhere near 15,000 rounds with FML and 117 FRN/GC cast bullets and never had a FTF or FTE, but I never used anything but 15 or 30 round GI mags.

I bought a foot locker full of 15's for $100 in 89 or 90. I kept 10 for me and sold the rest. I got $5 each until all of the sudden they became a $20 mag (my thought was pure BS!)
