So far accuracy with this caliber has been OK - but not as good overall as the .20 Tactical. If you reload, go with the .20 Tactical. Cheaper to shoot and about the same performance. If you just shoot factory stuff the .204 is your choice.

The .204 and the .243 are very different calibers - .204 has negligible recoil and muzzle blast and won't usually even exit larger varmints. Also is a lot more wind sensitive.
