None of the above, I'm a 223/CZ, 20PPC/Savage and 243/savage fan!
The couple of 204s in the safe run neck and neck with the 223s.Some days the 204s outshoot the 223s and some days the 223s do better.
If your new 204 likes and you feed it Hornady factory ammo it might outshoot the average 223 but will have a hard time keeping up with the 223ai. Good luck finding a reload the 204 likes that comes even close to factory velocities. Not saying it cant be done but IMHO it aint easy.
The 22-250 heats up very fast and recoil will keep you from seeing most of the action, on a good day I can watch a few hits from my 22-250 and 243 shootin 55 grainers but I'd rather hand it to a buddy and spot for him
I'm kinda kicking around the new 17Hornet round in a lightweight walkabout gun for seeing my hits?
