Non ported - Rob Roberts .660
same here, Rob knows benelli's but I shoot a 655 out of mine with magblends and it is pretty sweet.
Yeah, I just remember that Rob recommends .660 in the 28" barrel. I'm sure either would give a good pattern though.
you are correct, I shoot a 26" barrel so it may be tad different. When I originally called him he recommended both but wanted me to start with the 655, granted he just got done lengthening the forcing cone and porting it not sure if that makes much of a different.
