i've found references to 30-06 in 3 different mag lengths on the MDT page, 3.560", 3.715" and 3.850" (poly), what matters is what Savage offers in their OEM MDT chassis. 30-06 is not an available chambering. i'm planning to test 85's, 90's or more so maybe slightly more OAL? that's why i said the MDT MED(ium) 3.240" mag might work, the 30-06 / 300 WinMag 3.560" will work for sure. FWIW i have dies, brass and some bulk 55gr's for fire forming in a cheap rechambered barrel from EABCO before sourcing a quality fast twist barrel for the heavies
