Things I liked: This gun is very accurate, the key is pulling the trigger very slowly. Great knock down power! I am shooting groups at 40 yards that can be covered with a quarter; this is with the 25 cal, 22 cal, and 17 cal. I have killed squirrels at 60 + yards. These guns are so much fun to hunt with, better than firearms, its like hunting with a high power bow!
Things I would have changed: The trigger, thats it.
What others should know: This is a heavy gun, and it takes some man-power to cock it.
