head ... spinning... does anybody know what size the AICS mag is for the various 110 Precision Left Hand chamberings?

308 Win / 6.5 Creed will be the same and too short. 300 WinMag probably the best choice if the bolt head swaps but i have zero interest in the WinMag itself. 338 Lapua is interesting though, it's a little longer and bigger yet case head but i'd go Lapua over WinMag if the mags are the same. 300 PRC longer again and same case head as the WinMag, length may put it in a different class (barrel shank)? so what cartridge uses which AICS mag?

from what i've found so far, 3.240", 3.560", 3.715", 3.850" and 4.05" are available from MDT, i have no idea which Savage uses. i'm trying to figure out the least painful way to get to my end goal, .473" bolt head, 30-06 / 300 WinMag OAL 3.34" (3.240" would do) capable magazine for a somewhat obscure long range wildcat cartridge. the barrel shank size comes into play also for the barrel swap. the simplest way to break down the 1st step is,

what chambering 110 Precision LH should i start with to get the best action length / magazine OAL?

2nd question, can the 300 WinMag .532" bolt head be changed to .473"? (i see the LH LA bolt head available at Gun Shack if it's the right one)

3rd, what size barrel shanks do the 110 Precisions use, which chamberings are small / large?

Thanks In Advance
