Nitro's are really bad azz, but I think the new Hevi-shot MagBlend is going to give it a run for it's money..I watched my buddy shoot the Mag Blend thru a Rhino .660 in a 870SM yesterday 217 pellets in a 10" circle at 40 yards..That's pretty close to a Nitro if not as good and they are $4 bucks a shell verses $7-9..And don't have the wait time...
