Here is a 25cal Kral Puncher Breaker. With a new power adjuster, biathalon cocking lever, larger ports and new set of hammer springs set up for no hammer bounce. Plus with a bushing to fill the barrel band with the shroud removed, a Donnyfl Tanto makes it light, quiet and powerful.

30 shots at 55fpe (850+fps with 33.95JSB)

Only have to fill to 3000psi so my SCBA bottle lasts longer with more full fills.

Accurate too! Easily does ½"groups at 50 yards. 

Here's (3) 10 shot mags across the chrony.

856, 853, 844, 857, 854, 853, 858, 855, 859, 861

858, 858, 841, 852, 854. 866, 860, 864, 863, 863

864, 858, 861, 853, 861, 853, 856, 853, 857, 846

Barrel is recrowned and the bore is polished with JB Bore paste. I do 200 strokes changing the cotton squares every 50 strokes. A thorough clean both before and after polishing. 
 
Those Kral's have one hell of a valveing system...all the reviews I've been watching on the rebranded Crosman variants are stellar for a non regulated gun!

Accurate barrel's too...I'm thinking on trying out the Cayden in 22! And a few tips from your posts will make it even better...

Pyramyd air has a few Mega models in 22 right now. Slightly larger tube than the Cayden. Can be tuned to over 72 shots a fill at 900fps with 18.13gr JSB with only a few mods. It's the synthetic model with adjustable comb.

the valving stock is ok but if you want to shot 38 grain nelson slugs you have to open up the inside of the vave body in order to get air past the valve stem easier. I also have the same gun in same caliber. i have an fx slug liner on mine so i needed to do a good amount of machine work. The gun was a labor of love , I liked the looks of the gun so much that i had to get it.I then went on the mission to make it shoot as good as my impact and i does just that.A regulator would help you greatly ,you will get tighter groups and many moer shots.on your gun set it to 130 bar and pump the gun up to 4000 psi yuo will get 60 shots. My gun shots 38 grain slugs at 990 fps for 45 shots, the long transfer pot was also an issue i had to open it up to 6 mm . Which meant i also had to make a new power adjuster. like i said a labor of love but well worth it .

You keep filling that gun to 4000psi and it will eventually fail. Watch yourself. Doesn't need a reg at all. 25fps extreme spread on 30 shots and and only 20fps if you drop the highest and lowest of the string. I can get well over 70fpe on the stock valve body. Only needs the exhaust port opened up. I make a new power adjuster and it's at 5.2mm. I can easily stay around 1 MOA and get higher power and more shots than a regged version.
