Let's get this out of the way, this Cricket II is my absolute favorite out of the three Kalibrguns I own.
This is a .22 Cricket II with a 450mm barrel. I also am fortunate enough to have a .22 Cricket II Tactical (600mm barrel) and a .25 original Cricket (600mm barrel).
By today's crazy standards, this Cricket II at about 37 fpe with 18 grain pellets, is not a huge powerhouse. This tune is running the factory reg pressure (presumably about 125 bar or 1813 psi) and I just brought up the hammer spring tension to max it out and then back down a bit and it settled on a speedy 960 - 970 fps with FX 18s. It's hard to know where you are in the HS adjustment range, so here's a pic:
Yeah, this is a bit "hotter" than what's best for accuracy - I think that's more like 930 - 940 fps with this gun, but I was getting really excellent consistency with this stout hammer spring hit. Check this 3-mag (42 shot) string out. I was pretty surprised by the efficiency number here at this power.
You can see it drop off the reg shooting the 4th mag (56 shots):
Here's the trajectory info with this tune shooting FX 18s from 10 to 60 yards in 5 yard increments:
10y = -1.75 inches / + 4.5 md
15y = -1.25 inches / +2 md
20y = - .75 inches / +1 md
25y = - .50 inches / + .25 md
30y = zero
35y = +.50 inches / -.25 md
40y = +.50 inches / -.25 md
45y = zero
50y - -.50 inches / + .25 md
55y = -1 inches / + .50 md
60y = -1.25 inches / + .75 md
The scope is an Immersive Optics 10x24.
And the target used for testing this:
And for reference here is the target when doing the full string crony testing (45 yards, each group is a full clip). Wind was from my left to my right.
All-in-all this was a satisfying afternoon!
