Help needed for twist rate

John M · March 1, 2007, 10:09 AM

I have a Winchester Model 88 in a 308 and need to find the barrel twist rate.
Can anyone help?

Piece of cake...take a cleaning rod and mark it ( just dots ) with a black marker at 9, 10, 11, 12" and so on.

Put on a brush and insert it into the rifle, once the end of the rod is flush with the muzzle make a note of where the marker dots are. push the rod into the barrel until the dots make one revolution. Whichever mark is now at the muzzle corresponds to the twist rate of the barrel.

that'll work.. make sure the brush fits tight and is lubed
