I bet that 360 is a pussycat to shoot with anything you stuff in the cylinder Mike. Have you tried any hotrod 357, or 360 Dan Wesson loads in it yet? Also could you throw a caliper on it and measure the cylinder diameter? I'm curious to see how it compares with the Redhawk and Blackhawk. As I recall the large frame Dan Wessons are a tad larger than the Redhawk so it may have an even larger cylinder.
