I've made several posts about how I like to run my Urban on a low power/low fill setup. I discovered even going to 2k PSI was too much. Here's a list of the changes I've made to my Urban:
1. Swivel stud to mount a bipod
2. Longer trigger screw
3. Dropped power adjuster all the way down
4. Cut the barrel band off
I've found if I only go to 1500 PSI, I get 30 good shots at 50 yards, 20 with no hold over out to 65 yards (after adjusting scope for the difference in range), then another 10 holding between 1/2 and 1 dot for the last couple of shots. This takes me down to just above 1k psi on the gauge. It also only gives me about 13.5 FPE at the muzzle. I'm fine with that as I don't hunt, only target shooting, but at 13fpe, that's still plenty for rabbits and squirrels. Here's 30 shots at 50 yards in ideal conditions for shooting groups. Started to stop after 5, but they kept landing so I kept shooting. Had a few fliers, these were H&N FTT 14.66 straight from the tin and I did notice a couple of skirts weren't perfect. I can get a 30 shot group that is about an inch or so wider with CPHP. For $6 compared to $16 plus shipping, I compare it to the fact I've shot a lot more Thunderbolts than Federal Match so I shoot way more CPHP.
Also, shot these backwards, upside down using the reflection off a spoon. Just kidding, prone off the bipod with a rear bag.

Good shooting, I still haven’t done anything to my Urban other than loosening the screw on the barrel band. I get 25 good shots from 2900 psi down to 1500 psi. I’ve own it since December and it continues to impress with its accuracy.

Thanks Luis. One other change I forgot to mention was I also removed the O-ring from the magazine. It seemed no matter what I did it was binding and would not chamber smoothly. No issues at all after removing that. I had to change the way I hold the magazine while loading it, I basically keep a finger on the bottom of the hole, and there's enough tension left on the last pellet to keep it from falling out.
