One of the guys that I work with bought a chock made by Keith Anderson and patterened it with the Nitro triplex load and he put 324 pellets in a 10" circle at 40 yards. It was pretty amazing but almost to tight. He is shooting a 10 ga. BPS. The Anderson choke is a little tighter than the rhino so he is hoping the pattern will open up a little with the rhino. He hasn't patterned it yet though.
