I read to back off 5% of the max velocity at that given reg setting to be in "harmony". If I don't do that I think I could push those jsb redesigns 25.39gr at 950 at a 140 bar reg. What's the max you would push a redesign 25.39gr too? I only shoot out to 60 yards. No further.

So I maxed out the hammer (small adjuster to right below 5) VA all the way out and set 150 on the reg I was getting 965 fps on 25.39 grain pellets. As per the 95% tune recipe, 5% of 965 was 48 fps. So I lowered the hammer tension until I hit 48fps less than 965 (917fps). Then screwed in the VA...

So I just got the fx impact m4 22 compact (500mm). What's the realistic max speed I can push a 25 grain jsb monster to or similar slug? I want to make this a compact beast without buying a bunch of aftermarket parts. I'm open to suggestions on max reg pressure i should be going to and...

Here are the parts

My m4 has 2 rubber balls in the valve adjuster. However the diagram shows the small ball (pt57) behind the big ball (pt56). Mine was not like that. The small ball (pt57) was inside the spring (pt51). What correct? How is it supposed to be?

In modern digital optics with built-in laser range finders they can calculate your point of impact at different distances when you use the built in lrf (oneleaf nv500). To do so you have to put in all your ballistic info in the menu on the optic. One parameter is scope height. The problem is my...

Going off the air guns of Michigan tuning video listed in the original post, it's this right? *max out the hammer spring *fully back out vavle adjuster *Raise the reg until you hit your desired fps *slowly back off hammer spring until it drops 10 to 15 fps then bump it back up slightly to...

This right? I want to tune my 22 cal fx maverick compact to shoot my hades pellets at around 905. I first check my hammer spring screw and make sure it's at the max 6mm out and set wheel to 7. Set my second reg to 100 bar and 1st reg to 135 bar. Take shoots to see fps. Too high - lower reg...

What's a good standard deviation to shoot for? Over how many shots? Does shooting too fast affect the results?

I have a fx impact (factory power plenum) in 25 cal shooting jsb mk2 33.95 king heavys. I have a 600 mm barrel. What reg setting and hammer adjuster distance should i shoot for? Ive been at it for a week and i can't get good consistent fps spread. Help!

Question. I've been having this problem with my mk2 impact (factroy power plenum) in 25 cal slowly dropping fps over a shot string. Usually drops up to 20 fps over a few mags. The first few shots of my current string are around 977 then goes down to 967 after 40 shots and over a few more mags it...

I had a slug liner in yes, now i have my pellet liner in

I couldn't get my nsa 33.5 slugs to shoot good at any speed. So i went back to the good old pellets

600mm

How fast can i push the 25 cal jsb hades out of my impact while still being accurate?
