I think you'll find that many of us have opened up our barrel port to at least the same diameter as the transfer port, some have replaced their transfer port with one made of good steel so they could drill it out larger as well, along with the barrel port. Unless you modify the stock valve so it can breathe better there will only be so much return on the rest. I also believe the hammer spring in mine has grown weaker over time, could account for some drop unless you re-shim or have an adjuster.
I put a bigger plenum on my Nova Liberty and my reg is set at 2000 psi and the speed it is at is 855 fps with JSB 15.89 grain. However when it was with the original plenum the speed was 880 fps with JSB 15.89 grain. Wasn't the larger Plenum supposed to have increased the Speed of Shot? I didn't make any other changes, I just added the larger plenum.
Looks like the end of the road for the Liberty. While ATI removed the Airguns section from the drop down menu on their home page months ago, you could still order a synthetic Liberty as recent as two weeks ago via search or accessing the old airgun page url. Well, that airgun page is no longer there and searches for anything Liberty or airgun related produce zero hits.
I guess they will be going up in value sooner than later LOL

Does anybody remember if someone made a list of the orings in normal sizes for the liberty. I know I can buy a oring kit from capt Oring as I have 2 of them but want to order replacement Orings for the critical ones I've used.
Looks to me like they they swapped and adapted the Aspen and the Avenger. My guess is it has the same barrel (excellent) make and they took the 2 level power wheel from the Aspen (Nova Liberty) a nice feature. I'm betting that the plastic stock comes from the same manufacturer as the Avenger's. The sling mounts are a nice feature Too.Downside for me the manometer(air supply cylinder gage) positioned at the muzzle end and reverting to a fill probe. I think it likely that with the demand there will be a .25 cal gun coming in the future. With the accessible regulator and hammer spring adjustment all in all a very nice gun at an excellent price.
