Have not tried the Indian Creek, or any of the newer chokes through my Remington 11-87 with 21" barrel, I bought a Rhino .660 years ago and got excellent results with the Nitro's and Heavy Blends. Have yet to try the Long Beards but do plan on trying them as soon as we get some 60's around here. I do not remember what the pellet count was with the Nitro's but it was impressive. I got in the 220's with Heavy Blends 3".
Good luck
