I think this may have been discussed before but I thought it was worth mentioning. I got my Winchester .444 Black Shadow out of layaway this week and was going over the paperwork that came with it. The manufacturer's specifications card lists the rate of twist as 1 turn in 12 inches. :0 Has anyone else who owns a Black Shadow .444 had an opportunity to verify this. If it's true than bullets over 300 grains should be fine through this barrel, right?
