Last i heard you could not reload the 204 yet. The 223 of course has around 20 bullets you can load. This of course is all determined on the rate of twist your barrel has. I use a 223 and when you can reload the 204 i will then buy that barrel for my encore. 204 is affected by the wind more than the 223 also. Hope this helps.
As far as reloading, and i am not sure this is still the case, so i will check with western powders. The powder that is used in the factory loads is not available to the public yet. You can reload but cant get the same results yet. I will check though, this may have changed.
