You shooting armor plated whitetail?
Get yourself some ballistic gel and see what a solid 250 grain bullet does. 32” of gel no issue. Then the deer is leaking out of 2 holes. They don’t last long like that.
Those will definitely do the trick but I bet your JHP bullets slowed down enough to hold together will drop a whitetail like a sack of potatoes.

And I’m always interested in trying different ammo. I’ve yet to get a deer but I agree any decent JSP/JHP should be more than adequate for a deer.
I’ve also got some Buffalo Barnes 225 gr solid copper HPs but the HP is so massive I suspect the expansion will destroy a shit ton of meat. No idea though since I’ve yet to shoot a deer
