I'll be doing some jack rabbit hunting this weekend and possibly a coyote if I see any. I normaly use a .22-250 for this type of hunting but am eager to see how the PS90 will fair, particularly on the jacks. Quick target accusisition is a key whe you are going for a jack running full speed.
I used a 57 pistol last year to hunt jacks and I was a bit disappointed by the effects of the round. I can see the PS90 being very well suited to this task which requires running jmping and quick handling. I just wish it didn't have that horrible factory optic.
I'll let you know how it went when I get back. Sadly my new AK wont be in in time. Or maybe that is good because then the AK has no chance to do better than the FN, a $260 weapon showing up a $1500 one will make you feel silly.
