Should be good out to 15 yards, 20 max for chippers and yard vermin (my current comfortable iron sight range for .75-1" kill zones).

Guess it's nice to know a 15.89 @ 20+ pumps with the hammer spring tension up should drop a trash panda or groundhog with a brain shot from the correct angle and 15 yard max.

I also use the jsb rs 13.43. When I go to the range I usually will shot at 15yds and pump 4 times or the 25yds and pump 6 times of course I'm hitting paper.

I gotcha man, I was trying to find a balance between noise/trajectory/and backyard safe energy for both target fun and light duty pest control. I dislike chipmunks trying to get into the house and shed and vehicles, so moving target practice it is, lol.

The stock numbers on your 2289 were not too shabby at all, especially for punching paper. Is your setup still a carbine or have you gone pistol style setup?

I leave it as a carbine and have a 3-12x40 Bugbuster scope on it. The sweet spot is 25 yards but I have played around at 50 yards but that takes the full 10 pumps so I mostly use it at the 25 yard spot at the range and keep it within 1.5" group sometimes 1" if its not too windy and the coffee has worn off.

Today just wanted to see what the gun would do full out. 22 pumps with retained air shooting .22 polymags got to 694 fps! I'll never go that high again, but nice to see it lays it down. Totally enough for the wayward raccoon. 8) if I went heavier hammer spring I bet 715 fps is doable at 22 pump with polymags. . .

I am also hopeful for a 15 pump hunter 4-6pump paper AG.  694fps from a pumper...smokin!
If my Boss TP and holy grail screw ever get here I can reassemble and chrono.  Good thing I have three projects now...lol
