I still haven't gotten a pattern with my Nova (has a 26" barrel) that I'm thrilled about (highest I ever got was mid 170s with HS Undertaker .675 and 3.5" MagBlends), especially while my 20ga 870 is throwing up mid 160s. I did just get some H13 3.5" #7s so I'm hoping to change that this weekend. Not that I don't think that will work, but I know this gun is capable of much more. Just have to find what it likes...
