I just started today with the Rhino Came yesterday so today I shot it at 40yds with Winchester 3.5" 6 shot and put 109 hits in a 12" circle. Threw in a Nitro 3.5" 4X5X7 shot, my shot was low so I found the center of the majority of the patern and put a 12" cirle around it and came up with 279 hits You can bet I'll be moving my sights to adjust that mass right were it counts! In thye head Still a few more loads to test out but it looks like I'll be Nitro ammo through the Rhino tube this Spring.
