Hey BeardsnSpurs I use one in my Mossberg 835. It is a .680 and shoots extremely well. In a recent post i told the pellet count for the Nitro 4X5 Copper X7 Hevi and it was around 290 pellet count average in a 10 inch circle at 40 yds. That' s about what Nitro Ammo said it would get with their Rhino choke.
