I figured I might start posting in here again since I was the one that got this section started. So I bought an FX Maverick .22 Compact (500mm) Barrel. Then I picked up a .30 Cal Barrel change over kit from a friend also 500mm wanted to keep it compact also. I have other airguns that are sniper length barrels in every cal you can think of but this is my fun compact toy.
So .22 was a beast same hole accuracy at 46 meters (50yards) but I was having an issue with power when I switched over to the .30 barrel. Tried 50.15ge and 44.15gr slugs but both seemed to be under powered.
I reached out to FX. These people will email back in 5 min no matter what... You don't get this service with powder burners. I told them what I got and the issues I was having. So they shipped some free parts springs and heaver hammer and emailed me a tune to work with the .22 and .30 and then use the power wheel to change power on the fly.
Tune:
This tune is for a .30 caliber 500mm using 44.8grain JSB pellets. Adjust power wheel down for .22
Regulator 1 - 140 bar
Regulator 2 - 105 bar
Hammer adjustment screw - 5.98mm
Power wheel - 7
Your goal should be around 880fps
Ok got the parts and dumped all the air and started over tuning the two regulators.
My FX M3 .25 Sniper (700mm Barrel) has a three regulator system and a much more complex power wheel quick tune setup. I might post more about that later.
Some pics of what I did this morning.
