Guys, I am not going to hunt coyotes with an air rifle, but check out this review of the JSB Predator pellets, The review is from reviewcentre.com
Good Points: The JSB pellets have great penetration, fast and hard hitting. Dont dirty up the barrel to bad either.
Bad Points: None that I can think of.
General comments: I have just recentley bought a Crossman Seirra pro, shoots pellets at 1000 fps, So I got my target zeroed in at 40 yards! Even at that range the rifle still had 1.2 IN. groupings. After that, I went coyote hunting. It may sound inhumane, but I called a coyote in with my foxpro, and according to my range finder he was about 22 yards away. I was in a tree stand, I shot him right behind the ear. Dropped him on the spot! He weighed in at 36 pounds. Great pellets.
