The bonded 55 grain Norma Oryx has performed very well in my 223 under a load of ADI BM2 which can also be loaded in a 222. The one projectile I have recovered had mushroomed very well as the front of the Oryx is very soft and yet had great penetration. The recovered pill weighs 53 grains. I load these in three 223s, five 22-250s and a 220 Swift and they group very well at 100m in all of them. You could buy a box of Norma factory ammo just to try them.
