I shot 6 five shot groups, so 30 shots TOTAL, what would cause my POI to rise 3 inches on my last five shots? starting pressure was 210 bar ending was 150 bar. all help is much appreciated.
fx wildcat help
- Thread starter Muskrat.
- Start date
3 inches shift of POI??? Would check my scope/mounts first, if only POI shifted and not the tightness of the group itself.

group size stayed the same, it just landed 3 inches higher then the other groups, scope/mounts are snug not torqued down.

Could it be a clipping issue caused by the shroud being loose or readjusted. My Cricket will shift if I back the shroud off any at all.

What range? Did you use the wrong mil-dot for the last 3? (Silly question but, it happens to all of us.)
Check your shroud end cap to make sure it hasn't come loose. Also, unscrew it and take a look at it for signs of clipping.
Are you using adjustable mounts like the FX no limits? Maybe one/both came loose and moved on you.
With the info provided so far, it sounds like an optics related issue.
How's the scope? Proven to be reliable? Was it ever mounted on a springer?
What did you do between shot 25 and 26 (end of group 5, beginning of group 6)? Did you change anything? Drop the rifle? Bump it? Use a new/different tin of pellets?
What caliber are you shooting? (Shouldn't have anything to do with the shift, just curious)

Nice interrogation Tominco, that should get to the bottom of it.
When I saw Wildcat help I have to admit, I thought oh no here we go I hope it's not a rifle problem.
It sure does sound like the gun is doing it's part.

range was 55 yards, i wasn't using any holdover just the center crosshair
i checked the shroud end cap and its tight. i will remove it and check for possible clipping issues.
mounts and scope are just temporary until christmas, mounts where only $10 and scope is a center point ( who puts a CP scope on a FX rifle ? ) LOL
I didn't change anything during my last 5 shots, rifle is .25 caliber . this rifle has been very consistent so i knew something was off immediately.

Scope could simply have moved a little due to poor fixation (mounts <->dovetail or rings<->scope tube). If thats the case, the distance between your line of sight and the center of barrel *at the muzzle* have changed slightly and so did the POI.
Or, your scope's elevation turret silently went off a few clicks by itself. Has happened with some of my cheap low end, "toy" optics once. Not sure is such could happen to CP, but that could be more simple and more probable cause, as you said the shift of POI was so sudden.

Hope you get it straitened out. Was shooting my 22 wildcat today knocking centers out of clay pigeons at 100 yards. Hawk sidewinder scope. Love mine had a small issue with mag advancing but was able to fix it.

hmmm... 3" at 55yds = there's something really going on here! If you had said 125 or 150 I would have said keep practicing LOL!
There's nothing wrong with a CP on an FX my friend. We all started somewhere.
Good luck with Christmas I hope you get some awesome optics and mounts! Here's where I would start - lock down the scope and mounts as if they were your permanent setup. There's no reason to cut corners (especially if you're having issues) even for a temporary setup. Here's my thread on scope mounting. In there you will find a post about the scope "box test". It shouldn't take too long to re-mount your scope if you feel the need. After you confirm that the rifle, magazine, shroud, and end cap are all functioning properly and showing no signs of damage, I'd clean the barrel and magazine (just for the heck of it) and box test the scope.
Good luck!

tom, and everybody else, thank you for the great information. I will update this thread at a later date with good news. In the meantime I will try everything that was suggested.

Not familiar with your rifle but often, depending on the relationship between the hammer/valve springs and volume of air, when dropping off the reg several shots will be faster. IF that was what happen you might really think about backing off the hammer spring and or lower (?) reg. psi.
