smoothbore deer hunt

Arkansas muzzleloader season starts in two days, and I am taking out a smoothbore .69 cal 1842 springfield musket(repro). I'm just gonna be hunting the deer in my back yard... They've been wreaking havoc on my garden the last few years. I'll back it up with a .50 cal Lyman Plains pistol and a cap and ball revolver if game and fish allows those.

I wonder if I should put out some nut grub and try to get them a bit closer to my little blind? Thoughts and opinions?

That musket should be fine out to 70 yards.
