Thanks for the response.
Seems you & me are on the same page. One thing I'd like to add is that the superior (ballistic) 204 bullet is the 39 Sierra Blitzking. Safe loadings are just shy of 3900 FPS, runs away from the 32 grainers at max point blank range, and the Eskimo Traj calculator says it bucks the wind within an inch of anything out to 500 yards--- And considerably better than any 32 grain bullet.
After limited experience with mine I can't help but wonder about a 39 Blitzking with a little tougher jacket. I've seen what can happen on the way out of the hide. As a noob coyoter I'm still scratching my head with the only flavor being rapid fragmentation.
There's nothing wrong with any of the 3 calibers you addressed. Always subtle limitations and advantages. As Tim and I agree, the 204 just needs to wait its turn for ideally constructed bullets. One very cool aspect of the 204--- your eyeball never leaves the target upon firing. I shot coyotes last weekend where the lack of recoil enabled me to watch the impact and the response whether zap-flop or zap-twitch... Ability to determine follow up is immediate- Very useful!
