IN REFERENCE TO THE DUAL CALIBER FEATURE/S:As mentioned, you can order the FD-PCP in .177 or .22. If you would like to have Dual Caliber Capabilities, just purchase an extra barrel in the caliber you would like to have (only $20.00 for extra barrel/s.) and a set of extra o-rings for the barrel.The o-ring size for the barrel is 012 and you can get them at your local Auto Parts Store or local Hardware Store. Only about .79 per pack or set.The reason for the extra o-rings, is that you may damage the ones on the barrel you are removing from the FD-PCP and will need to replace them with the new ones. Also, you will need some for the extra barrel.From what I have seen personally, one should be able to switch out the barrel in a matter of minutes.Just always be sure to remember that your FD-PCP is not cocked or loaded before doing any barrel switching!Also, be sure to always use the proper tools too, as you do not want to damage any of the parts.Al.
WARNING!I would like to let everyone know in this Tech Data Section that if you let the pressure get too low in the tube of your FD-PCP, the valve seal may start to leak.
IN REFERENCE TO SHOT STRING TEST RESULTS and TUNING:This is an average 923-fps and 27.05-fpe using 14.3-grain pellets! For the purpose of hunting, a shot count of 10-13 from a low-pressure PCP, such as the Flying Dragon-PCP is all you really need imho.Job well done utilizing the Power Adjuster Screw Feature and the recommended 1500-psi fill in an effort to dial-in that sweet-spot!I'd say the Flying Dragon-PCP is most definately a capable Hunter of small game!"Finally... FD-PCP SUCCESS... I shot several 20 shot strings today adjusting the power setting to various spots, never quite happy with the result. I finally found the holy grail (as a hunter, anyway) and was able to shoot this string:(.22 cal, 14.3, CPHP, 1500 psi on my guage)1 8732 8993 9294 9505 9536 9557 9508 9449 92610 92511 91112 90113 887I did not finish the 20 shot string because I know the power would fall off rapidly. I will simply quit shooting and refill after shot 13. Most of the other strings I shot had the power curve shifted toward the end of the string, which for a hunter is not ideal. This setting shifted the power curve towards the front of the string which is better for hunting. The string is not perfect, but if I factor out the first and last shot I am pretty close to Bob's 4% . I know this setting is not for everyone, especially those more interested in shot count, but I am elated, it is exactly what I hoped I could do with the FD-PCP. Now for some accuracy tests!!!"
