I got mine at a store called Sportsman's Warehouse...I don't know if there is one in your area....
Having said that...It was my first box and while it seems to live up to all the hype...I'm going to do what BPS suggests...I'm going to get a box of No. 4 buck and test pattern it...If it patterns, I'm going with it and I'll save a lot of money....
Look at the thread on the shooting forum about shogun pattern tests...Dead Coyote may have the steam to kill a dog at 70 yards as they claim, but no one seems to be able to get consistent patterns beyond the 50 yard mark...I suspect that from zero to 45 or 50 yards buckshot will make a coyote just as dead as Dead Coyote and do it much cheaper....
The country I hunt is a mix of brush and oak covered rolling hills....There are places where you can see forever, but there are also a lot of places to set up in the brush and cover...I set up in areas that favor the use of a shotgun. When hunting "shotgun" country. 50 yards is a long way and it looks like a long way....The last animal I shot with Dead Coyote was about 25 yards from me and a 3 inch load of buckshot would have done the job nicely....
