I see that a few people give the common answers of both sides regarding using a .40 on deer and the one making things very personal is you.
If it is legal in your state, then you should feel some consolation that your law makers share your opinion. (or bent to the will of voters who do)
People spoke about their choices and they dared to disagree with your point of view.
Please do not demand that all of us accept your opinion when we honestly hold differing ones.
For all I care, you can stalk deer with a sharp needle and a soda straw.
But if shot placement is all that is needed, why limit the ball size at all. Prove it with a .32. For that matter, why not a .177 cal pellet? Maybe your legislature will pass that one. Hopefully not though, because, size does matter in killing anything. Temporary cavitation, wound channel, bleed out...
We just disagree about the size of projectile hat one should responsibly use in cleanly taking deer.
Can't this be done without crawling into the gutter?
