Sorry, it was a cryptic question... I was wondering if, in your experience with the 204 Ruger, do you consider it to have roughly equivalent wounding power to 223 (moderate weight 223 projectiles, not the really heavy stuff) ?
Kinetic energy levels are about the same, but the 223 projectile as 20% more cross sectional area, and a 62 grain bullet is 37% more massive than a 45 grain bullet... but the proof is in the real world performance on animal flesh.
I don't want to put words in your mouth, but from your description of coyote kills, it sounds like 204 Ruger IS comparable to 223. But I will let you say that...
