Well Trev I guess with 100% honesty I would have to say no, not with 35gr .224 bullets. I did lose 1 coyote that I shot with a 40gr vmax which hit he shoulder and the dog spun, then ran down a ravine. I also lot two coyotes in similar situations with the 32gr in the .204Ruger before I switched to 35gr bergers for that set up.
In all three cases I'm sure the coyote died eventually, it just wasn't how I wanted it to work out. I've also had coyote drop like a sack of hammers with both bullets mentioned above.
I've also shot deer with the 50gr tsx and the 55gr Sp w/cannuler from Hornady. I was more impressed with the performance of the Hornady than tsx. The tsx however penetrated like nobody's business. So I'd use either again if situation arose.
The 35gr .224 bullets are generally designed for 22hornet/fireball velocity shooting of rodents. If put behind the shoulder I have no doubt they'll liquefy the lungs and drop the coyote. My only point was shoulder hits at .223 velocities would likely result in bullet splashes.
So, without putting too fine a point on it, you are chucking the baby out with the bath water, on some results that you cannot actually confirm were the fault of the bullets you used.
If you don't eventually recover them and assess the damage done, you have no proof that the results were not from your own shooting, your rifle having been whacked and misaligned, or both.
BTDT. No lie. But I have also watched hits that should (according to the 'knowledge' out there) not have had any effect at all, drop an animal and prove that a decent hit and bullet that supposedly doesn't work, does.
On the other hand, I have been directly involved with several recoveries (long since past any feelings of guilt over) that were eventually recovered after having been supposedly hit well, that actually were not. Y'know, the guy that shot the deer was sure he hit ribs, but the leg recovered at the scene said otherwise...And, well, didn't feel too bad about using a flashlight, if ya know what I mean...
And a couple were mine... Nothing like following the ravens in, to find the buck you shot that morning...Lousy feeling, but I knew by the end, that it had nothing whatsoever to do with the bullet or load.
Educational.
