It's illegal to hunt over bait here in PA, but Gander Mountain still sells saltblocks and cracked corn by the truckload. So let's avoid the whole "legal/illegal" issue by pretending that everything goes. This discussion is only constrained by what YOU would/would not use.

Personally, if I had a product available that would ensure that every hit was a quick, humane kill - and it DIDN'T ruin the meat - I would use it. Even though I don't eat the deer I shoot (I give them all away) - it would still be a dealbreaker for me.

But, if I was dialed in on a once-in-a-lifetime deer. . . like a lot of other people, I'm sure, my opinion may be "subject to change."
