What a day! You've spotted Bigfoot and are hot to capture him. Can you shoot? No. In most states (Texas being a notable exception), you can't shoot any creature that's not on the list of huntable (new word) animals. We suspect this is less for Bigfoot's protection than for the safety of particularly hirsute people. A few states, particularly the Pacific Northwest, specifically name Bigfoot as protected.
If you're determined to capture the big guy, it is recommended that you use a trap. Be sure it's big enough for him to lie down, stand up and turn around. It's only humane.
So, before we head out to the woods, let's polish up our bidding skills. We want to take down the opponents, but not with bullets.
