I can't seem to get the straight scoop on this. I don't have access to my .270 right now but I read, somewhere, that in 1980 ( or always?) Remington made the Mod 700 in .270 with a 9 1/2" twist. Can anyone verify this? Thanks. Jim

I don't think so myself. In the 80's there were no bullets that needed faster than 1 in 10.

Thanks Craigster
I’ve had a M 70 6.5x55 a few years and wasn’t sure of the ROT.
1 - 7.87 is better than I anticipated and better than SOME have said.
I appreciate you taking the time and effort to post the link.

Jerry I’m doubtful that anyone can consistently rifle a bore to .87

JW I think you are probably right. I'm just going by their stats. ATST I'd gladly accept 1--8 twist.  Good to hear from you. Jerry

I always thought a 1-7.88" ROT was better.

In the days before smart levels, we use levels with a degree dial divided into 2 degrees between marks. The engineers would want a flange roll of 7 degrees and 15 minutes. I asked one once why did they put minutes because our tools weren’t accurate enough for that and that and he said because that was how it calculated.

For what ii is worth guys, 1/7.87 works out to 1/200 mm. Maybe the link says that. If so, sorry for the redundancy.

Just a heads up. I've got the same table on .270 Winchester twist rate in one of my Speer manuals & the listed 1/9" twist rate for Mannlicher Schoenaurer is actually 1/10" for the Model 1952 that I own. I've measured it several times & it always come out to 1/10" so the info may not be 100% correct for all manufactures & years.
