@ Tom Roberts, Though in theory a .410 should do what a 12 does at 45 yds (same shot fps and all that) with heavy shot, you don't have the pattern size or shot string, I believe that's why everyone thinks a .410 won't reach out that far. I know a guy who's a monster with a .410, His initials are Stuart Fairbank! hehe. The guy can flat out shoot a .410, I am sure Stuart can get it done long distance with this little gun, as for us average shooters I limit myself to under 25 yds with mine and most of the time they are clean kills, as far as cripples that's a different story. My rule is the instant they hit the water if they are not belly up, they get another barrell. If you are refering to do I cripple a lot of birds with it, no, for above reasons. Someone eluded to "if can't wait for the close shots, don't use the pop gun" and I agree. In the hands of a skilled shooter, no prob, but for the rest of us, use on closer shots. I had a Greater Canada hovering over the deeks at 15 yds, sat up and killed him dead! They don't get much bigger than that! -Tom of the MLB
