I've got the TK-2000 and swear by it. I took a tom in the spring at 60 yards and dropped it dead in its tracks. These work by using a 3-1/2" shot cup and you fill it all the way up with #4 shot or what your state allows. I think it totals to around 420 pellets if memory serves me. So you have 420 pellets shooting out at the bird vs 100 or so from a standard shotgun. At 25 yards it blows out the target big enough to put your fist through. One of the best I've seen. I bought mine from a guy whowon it at a Wild Turkey banquet for only 100 bucks brand new in box. It was a steal but he made money as it only cost him 10 bucks for the ticket and he did'nt blackpowder hunt. If I could find that deal again I would be on it.
