Just got the .25 Mrod as a gift and I got a first kill with it. Those polymags are crazy in .25 cal. I've used them in .22 cal and they were devistating as well but I never got a result like in the pics below. I've seen pictures posted by other hunters and their results. Some of those pics made you go WOW! I believe I happen to see the pic here in a post on the about .25 cal polymag results. I've been wanting to try them out in one of my .25 rifles and I finally got a chance the other day.
I took this starling sitting on top a lamp post @ 30 yards off hand.
this is how I found him laying after being shot
rolled it over and was amazed at the results
I can't remember what my fill pressure was exactly but I believe it was in the mid 2000 area which puts this pellet in the 860-870fps range. Wondering what this bird would have looked like if I would have used my custom .25 I built launching 26gr polymags @ 990fps
