Had a friend show me a FN PS90 and he wanted to know what I thought it would do as a coyote calling gun.It is a 5.7X28,I saw a bullet and it looked pretty tiny compared to my 22-250.Don't know about the velocity of factory ammo.It may work for coyotes at under 100 yds but I really don't know,it is compact and has a short barrel.Anyone have any experience with it as a coyote gun? Looks like more of a personal defense weapon.
