I thought that it would be a good idea to put a little table together of my chronograph results for all my firearm collection and share it on the forum. I'm hoping that it maybe of some use to a few members who are looking for pointers as to which gun does what FPS or just to compare performance against their own firearms.
| Firearm | FPS | shot string | Projectile | Notes |
| ASG Classic X9 | 210.8 | 60 | 5.1grn steel BB | None |
| Colt Python 4" BB | 220.8 | 72 | RWS mk 4.49mm 7grn | Increased the size of ports in the valve stem |
| KWC Luger P08 | 228.1 | 42 | 5.1grn steel BB | None |

Notes -
The H&N Excite Plinking pellets have been pellet sized down to 4.52mm using an appropriate pellet sizer.
The RWS Meisterkugeln 4.49mm pellets are straight from the tin (unsized).
The 5.1 grain steel BBs are either manufactured by Umarex or ASG.
Increasing the size of the ports in the valve stem was done using a dremmel rotary tool fitted with a diamond tipped bit, the increased size of the port was all gauged by 'eye'.
Where the notation 'BB' appears in the Firearm column it denotes that the firearm has a smoothbore barrel that was originally intended to fire BBs but has been subsequently used for lead pellets.
The base ambient temperatures varied during these tests, under different temperatures different results will be found and as such the figures are intended as a rough guide to benchmarking any CO2 replica firearms.
The FPS column denotes the average fps across the whole shot string, e.g. The Webley mkVI averages 412.7 fps across the 72 shot string.
Any member wishing to contribute to this thread by adding their own findings will be greatly appreciated, whether that be their findings on any firearm that doesn't appear in the table above or even repeating their findings for any firearms already noted, all information and findings will be gratefully received. The more information we have and the more results we collate, the better understanding we will have of the outputs of any firearms, whether that be standard (straight out of the box) or enhanced (individual changes made by owners) versions.
