Barrel Twist Rate - Rem Model 700 Mountain Rifle 7mm Express/.280 Remington

[sonnydaniels]

I have a Remington Model 700 Mountain Rifle in .280 Remington--it was given to me many years ago by my father. It was manufactured in the 1980's--I have tried to look up the twist rate on the barrel, but I find conflicting information. I know the new ones are 1/10, but I heard the older ones were around 1:9-1:9.25. Does any of you knowledgeable folks have any idea what it would be from that time period? Thank you in advance.

You can check it with a cleaning rod, jag, patch and Sharpie.
Get the patch started in the bore.
With the Sharpie mark starting point and then mark top dead center about 12" back.
Start pushing the patch and watch for your TDC mark to come back around (up).
Now mark stopping point and finish pushing the patch through.
Measure the distance between start and stop points.
Voila ! You now know your twist rate.
