Relying on low pressure to make the valve easy to open forces one to run a longer 24" barrel which makes any airgun more unwieldy. At 1000 psi a .325" poppet (not sure what they use, just random ideal diameter selected) has around 83 lbs of force holding it shut opposed to 165 lbs at 2000 psi...

Mmmmm.....I am proud of Mike, too many people gooning over airguns all day every day. One thing for it to be a chapter of ones life, another to be the entire book.

Simply put, a plenum is the amount of potential energy reserved inside the regulated volume of air inside an airgun, measured by volume. More plenum = more energy potential, however the potential of energy greatly tapers off once you exceed about 1.5CC per FPE. See below as an example, given...

#1) Weighing and sorting pellets will vastly improve your ES in any given string. I have heard JTS/AEA aren't as imperative when it comes to weight/sorting but JSB/H&N ect all really need this. A .1 gr difference in projectile weight can have a .5-1fps difference at the muzzle. An example I can...

*disclaimer, long winded* I feel one of the primary issues with heavily moderated online forums/communities is (for Americans) we're indoctrinated with the concept of free speech, which such mediums lack, but some take free speech too far, freely spewing nonsense. So it's an issue on both ends...

Since you mention a desire for lightening the trigger, one method to decrease the trigger pull weight on most pcp's is to lighten the hammer spring, but to do that, you generally have to modify the valve to require less force to open, and for more, less force trying to close it. (Not for the...

Aluminum or TI air cylinder, balanced the rifle. (Aftermarket part available, which my custom marauder has) Increase fill pressure rating from 3,000 psi to 3,600 psi Turret style air metering wheel with 6-8 repeatable settings instead of the Velocity Metering Screw. Design is in my head...
