I've used Norma Oryx on everything I've shot from duiker and up except on one roebuck so I'm very familiar with them. This has been 180 gr 308 though at moderate velocity. A lot of people have reported somewhat inconsistent performance with the Oryx at higher velocities though so I'm somewhat hesitant to run them in a 223. I've also pretty much only heard good stuff about the ttsx and since a 223 will be a new caliber to me and I'll have to work up loads regardless so it'll be a good opportunity to try the barnes. I'm sure a roebuck will be just as dead from a well placed Oryx as a ttsx though so it's mainly to try something new and not out of distrust for the Oryx.Norma, made in Sweden, I believe should have some good offerings for you. Any Norma ammunition I have used in various calibers has produced good results.
Apart from the 120 grain ballistic tip in 6,5x55. That caused excessive meat damage whereas the Oryx bullet is great. There is a 53 grain bullet in 22 caliber available.
