If you barrel is marked SA 116865614 then its 1/12 twist, I just had mine rebarreled with one and its a hummer with the 125TnT, and Canadianicon IVI 7.62 is scairy accurate, 168 handloads with Sierra or Nosler CC did very well also, I'm happay as a clam! T/E 1 M/E 0, my next batch of reloads I'm looking at is the 135 Sierra HPBT.

My complaints are ejection, its all over from 1 too 4 o'clock all clear the action about 20ft worth, #2 sometimes the case mouth takes a good wack, I think a coil and a half off the ejector spring may help solve these two issues.

Shooting impressions, I have a M1 in 30.06 and a M1Aicon in 7.62 but a M1 in 7.62 is a different animal, I would say that a M1 in 7.62 is a all day shooter it has less felt recoil than my M1A with the same loads, and NO I'm not telling the wife she can stick with her NM/AR.
