By moving from traditional old tech bulllets to copper solids in these versatile middle calibers to I risk punching clear through smaller deer becaue the Bullets are too tough? .
Don't we risk punching clear through smaller deer with any bullet? Why is that a problem?
I prefer 2 holes for blood exiting, but I'd also like the bullet to expand and deposit some energy in the animal, cause some additional tissue damage and put it down more efficiently.
Then listen to steelhead's advice and go lighter/faster. You'll get both pass-throughs and better expansion.
Exactly what I was thinking.
