I have a couple relatively quick loads in the 22 Nosler. 40 Nosler BT at a bit over 3900, 55 Nosler BT at 3550, and a 65 Sierra game king in Hagar brass at 3150. All these loads are very hard on the brass, and when pushed hard the Hagar brass doesn't hold up any better than the Nosler stuff. These speeds are out of a 20" White Oak barrel. For comparison in a .223 using a 40 NBT and the same powder it takes a 26" barrel to get 3950. In a 16" 22-250 I can get 3500 with a 55 NBT. I don't know if I would call the 22 Nosler the best thing since sliced bread, but it does fill the space between my .223 and 22-250 and works in an AR platform with a reasonably short barrel.
