Here you go Eddie..first shot string from my 18" condor
Eddie has been “dying” to see some 18″ barrel numbers. I received my 18″ barrel from Mike and he was kind enough to give it that ol’ knifemaker polish. Smooth as glass all around the breech and man that hammer slides back like its riding on grease, and when you load the pellets in, it feels like your pushing them into silk…thanks again, Mike.
Okay, first let me apologize for the misinformation that was posted with my original shot string from my 24″ barrel. I did not have any feeler gauges at the time and with the help of a few members…we deduced my TH to be .100 to .105…Well, I finally picked up a set of gauges and my TH is no where near that setting, it is .88 😳 Sorry guys!
The only variable that is different is the change from the 24″ barrel to the 18″ barrel. PW is the same (3) and TH the same (.88) One other factor that may be negligible (you tell me?) Is the string shot with the 24″ barrel was done on a day of 80+ degrees outside. The tank was filled to 2900 psi in a 75degree inside temp and shot in around the same temp.
Todays string was filled to 2900 psi in a temp of 64 and shot in a temp of around 55 degrees (don’t know if it truly matters or not???)

I surely didn’t get as good of a string as I did with the 24″ barrel. It seems that the difference in fps ranged from 50 to 100. The meat of the curve being a nearly 100 fps difference. This is only my first test and one other thing is that it was shot from a freshly cleaned barrel, so I imagine it will get a little faster once it leads in. Please put in your 2 cents as I plan on keeping this an 18″ Condor carbine. Thanks.

x2 It may shorten the string, and will give you higher numbers but it should also pull the spread in some…
Dontcha just love the 18″ grit’? Really does make the rifle more managable and less like swinging a flagpole about…. 😆
