It should be a 1 in 10 twist.
You can check it with a tight patch by placing a mark on top of the cleaning rod with it almost
all the way down the barrel and while pulling the patched rod backwards watch the mark
and when it comes back up measure back to the back of the action (Where the mark was
made in the first place . This will tell you what it is. If it is a little (1/4 or 1/2" off dont worry
the factory barrel twist are mostly even numbers 1 in 9, 1 in 10 , 1 in 12, ETC.
