Okay, I just finished re-checking all of my velocities with BOTH the .177 and the .22 Gamo CFX airguns.
I only fired a couple of "wake up" shots to start with, then I took one reading with each pellet.
Okay, on with the numbers.
.22 Muzzle Velocities:
H&N Baracuda Match (aka Beeman Kodiak) - 521
Beeman Ram Jet - 592
Beeman Crow-Magnum - 555
Beeman Silver Arrow - 608
Beeman Field Target Special - 615
RWS Super H-Point - 640
RWS Superdome - 660
JSB Predator Polymer Tip - 626
JSB Exact - 566
.177 Muzzle Velocities:
Beeman Kodiak - 687
Beeman Ram Jet - 766
Beeman Crow-Magnum - 771
Beeman Silver Ace - 774
Beeman Coated Hollow Point - 802
Gamo Magnum - 817
Gamo Rocket - 723
Gamo Tomahawk - 732
RWS Super H-Point - 891
RWS Superdome - 796
JSB Predator Polymer Tip - 768
JSB Exact - 745
Crosman Premier Ultra Magnum - 641
Crosman Premier Hollow Point - 822
Obviously, there has been some variation from my original numbers, especially with the .22.
No longer does a given pellet in .22 outrun the same type in .177, and the Baracudas are coming out approximately at the same speed as the OP is getting.
In fact, I am getting about 30fps LESS than Davee1.
My apologies for having such out of whack numbers initially, causing you so much consternation.
I DID Chrony my .22 when it was brand new, so I suspect that I _DID_ have dieseling my numbers quite a lot.
Either way, I feel far from cheated with both of my Gamos.
In fact, I think they are a tremendous bargain.
To better them significantly, I would probably have to plunk down two or three times what I gave for them with a Beeman R1, HW97, Beeman RX-2, or Air Arms TX-2000.
