Not sure John, but its dead easy to find out yourself with a cleaning rod. Hope im not teaching you to suck eggs, but the way i have done it is to push the cleaning rod plus brush into the bore and using a pen, mark off a point on the cleaning rod level with a point on the rifle, also put a line on the rod lengthways so you can watch the rotation. Once this is done, push the rod until the lenghtways mark has done one rotation and then mark off another line using the same point on the rifle. When you take the rod out, just measure the distance between two marks and that will tell you your twist.
Im rubbish at explaining things but hope thats clear enough.
How are your deer looking up there?
