Terminal Ballistics:
.30cal or .22cal for Feral Pigeons?
I THINK, I KNOW what's the better caliber for feral pigeons — but then, my wife tells me that I'm not always right when I THINK I'm right.
So, please, correct me or enlighten me at least.

I am aware —
and blatantly disregard

—
the disadvantages of the .30cal over .22cal. Here in no particular order:
▪ more danger of damage apart from damaged pigeons
▪ less shots per charge
▪ louder
▪ more expensive per shot

Now, I am looking at shooting the
.30cal with an MV of 540fps — for a ME of 32FPE — so, very low velocity, very low power for a .30cal.
That should eliminate the disadvantages of noise and low shot count.
▪ What about the danger to stuff other than pigeons?
▪ The trajectory is rather loopy, so my PBR is only 36y (33m) short. My largest distances are 60y, typical is 25-45y.
Do you have anything to add here? Please, do so.
The advantage of the .30cal — using the JSB 50.15gr dome at 540fps MV —
hitting pigeons at 50y with 25FPE (473fps):
▪ a bigger hole in the pigeon = equates to quicker kill and on marginal shots, a kill at all.
Is this correct thinking?
What comments do you have?
This is not academic, I have a .30cal rig with these specs.
Thanks!
