Can you or anyone give me the spec on the Poppet outer diameter from the ST kit? I have mine all installed and forgot to measure it. Found a neat spread sheet calc and it needs poppet diameter. Thanks
thanks haj. you rock man. gauntlet is coming along nicely. seems a bit odd that i have to crank my stk in 8+ turns from flush out to get to 888 fps. I know ports need to be opened up. i did do the barrel to 11/64". It there a better or aftermarket valve system that would fit, so i dont have to worry about messing up a hard to get factory unit?
ok. so you count turns in 180 degree increments. i was counting in full turns. i know i started off flush put on one turn checking each shot over my prochrono and stopped once i saw speed no longer increase, backed off one turn and used 1/4 turns to bring back up to my target speed.this is my first time modifying an airgun, but im very technical and detailed. been an automotive tech for 20 years to i know my way around tools of all manner.
Gauntlet .177 and .25. Using a .45l bottle now. If I swap out the lower pressure rupture disc for a PI on the reg. Will it display the output pressure of my reg? Is there an equation to calculate output pressure of regulator? .177 - 10.5gn at 1050 fps I think it should be more but Im having pellet probe oring issues with .177..25 - 28.24gn h&n barracuda hunter extreme at 925 fps.And have you had issues with broken belleville washers( only the black ones)?
