150 yards in some locals and you're never going to find it.
Glad you were able to put another in him and that, no doubt, is the reason you got him.
I'll take big and slow over small and fast.
22's are deadly above the shoulder.
I shoot 3 or 4 deer a year for a long time now and generally get to see them go down.
Used/use everything from 500 gr. bullets in a muzzle loader,slugs,arrows, down to 45 gr. Barnes in 223 on the low end.
Plenty of places here where 150 yards is a eternity and this area nudging that way so I understand your concern with dropping them in short order.
One bullet remained in the offside breaking the leg.
Went between ribs rather than taking one out on entrance.
The other went through a lot of deer and exited.
These Scirocco's transfer energy well and usually a deer will just shudder and go down.
I think looking to big and slow for a fix in this case is heading in the wrong direction.
It would of took different/better placement.
This buck was also a stud actively chasing a doe, keeping lesser bucks at bay, and likely had plenty of adrenaline on board.
He showed up out of no where and likely was about to depart to same.
But it is what it is.
Though having to track makes you feel like you should of done your end better and anxious once in a while isn't necessarily a bad thing.
Helps keep you a bit sharp at it and teaches you bit about the way a deer thinks.
