Took some time out to test my Rapids newly "NEUTERED" barrel. Haven't had much shooting time with her yet as the winds/weather does not cooperate very much. The SANTA ANA winds are in effect here in Cali. But I did manage to at least sight her in and get a group and do some quick blasting with the shorter barrel installed.
Ernie over on Airgun Advise did the work for me and he removed right at 3" from the stock 24" barrel. Since installing his awesomely crafted laminate stock, it added some length to an already long gun. And I've wanted to chop the barrel down for a while now so.....what better time?
As expected, there was a FPS loss with the barrel trimmed down. The gun was set up to push JSB Kings at 940 FPS and now with the 3"s removed, velocity is around 910 FPS. I have yet to RE-TUNE the gun as I wanted to see if the gun/barrel would remain as accurate with the barrel shortened at the current power setting. It still shoots great but has lost just a tad of the accuracy but again, that's expected now as the FPS has changed. So again, more tuning and testing to come. But, I was able to still smack eggs at 100 yards while placing the eggs or their sides instead of standing them up. Much smaller target that way......lol.
With the switch of the stock and a shorter barrel and also the smaller 400cc bottle, the gun is no longer front heavy and is more balanced. Stay tuned as more will covered on this gun and it's new barrel length.
Here is a pic of the gun with the standard 24" barrel:

1st group shot with JSB Kings and the shorter barrel at 50 yards. The target dots are exactly 5/8" and the 1st shot pushed it through the Styrofoam plate:
