Please help me find accurate info on the twist rate for a Win .30-06 sprg Model 70 in the 195xxx serial number range. I have seen 1-10 and 1-12 as most likely but could not trust the sources.
Thanks in advance for your help.

Welcome to Gunloads uofu4u2.
I have no data here on m70's, but measuring it is not difficult. All you need is a cleaning rod with a slotted jag, a patch, and a measuring tape. In fact, it should take longer to get out the cleaning supplies than to make the measurement.
Put a tightly fitting patch into the jag and push it in the barrel, almost to the end. Make a "flag" of masking tape on the rod at the other end flush with the end of the action and note which way it is pointing. Pull it through slowly until the flag has made one revolution and is pointing again in the same direction. Measure from the flag to the action for the rate of twist.
