Weird wildcat

My 22 wildcat is just dead on accurate and I couldn't be happier. Thing is it shoots the first shot of the day 2 inches low and to the right at 50 yards. 2nd shot is 1 inch low and to the right. Then it's dead on the rest of the day. It's so predictable I cam adjust for these first two shots and be dead on. I can shoot it in the morning and it will still be dead on that night. Next morning, 2 inch low and right. It's had about 5K rounds through it. Now WHAT would POSSABLY cause this? For all I know it could be the scope. 
 
I've had a couple rifles like that ....Its NOT the scope , I kinda gave up on trying to figure it out because I posted a thread on another forum and got so many replies with ideas anywhere from hammer spring needing to be warmed up , to bad lubes , to regulators , orings, and magnetic forces that the government is responsible for ..
Hopefully Ernest or one of the guys who know a lot more than me will chime in with some help. Just don't waste time swapping scopes for what's a fairly common PCP gremiln :)
 
This was the case with my Impact, until the shroud was replaced with a fixed one! First shot of the string/day (especially after the shroud was extended) would always be a 'flyer'. Chronographed those first day shots as thought maybe the regulator required resetting but it was always fine. Checked magazines for problems and even replaced a few seals but the issue persisted. After replacing the shroud, so far there is no recurrence. 

If this is a regular occurrence, maybe chrono to rule out the regulator. And then next day shoot without the shroud? You've put a fair bit of lead through it, maybe clean the shroud too.
 
Probably regulator creep. I usually take 2 -3 shots before I start shooting. Also a little bit of sticktion like friction in that everything has been sitting under pressure like the valve and springs and regulator if regulated. Move all the parts a couple times and things set back to normal.
Was common back in my paintball days to shoot a couple shots to free up the regulator if it had been sitting it would creep up in pressure. Since the guns operated on low pressure they would have a hard time getting the valve open, couple of low powered shots and it was back in business.
 
MichaelI've had a few rifles that did this. Is it possible that the way the gun is stored has anything to do with it? Then the first shot or two realign or settle everything back in place?


Michael has a point. I've also noticed that resting the rifle on the bottle results in the POI shift.

Another thing to do is to not cock the rifle after the lost shot (to remove mag) before storing for the night. Leave it on the bipod as is, and next day cock and load and shoot. See if that makes a difference. Also only handle the stock, not the bottle/barrel etc.
 
with all the AG that has this issue while in the shop---this is the most comm cause:

1st:
the reg pressure is to high shooting at max speed of 950fps and the HSTA was adjusted to a slower speed of 880fps. for consistency the HSTA is for minor speed adjustment-----> let say under 15fps.

2nd: 
the HSTA is adjusted to over power the reg limitation, that's when the HSTA is tighten down till speed start to slow down.

I fix this issue by adjusting the reg pressure to max out at a set speed--let say the owner whats 890-895fps, when set this way its most consistent ES and 1st shot in the morning being in the ES range.

when the owner whats to shoot from high power 950fps to low power 750fps he has to live with the 1st shot being low in matter of hours idle or next day, I just tell him to shoot air two times then his good to go.

you have to take a lot of time interval testing to find out how much time you have setting idle before it really start to slow down. let say 1 hour is my max idle time--for hunting and pinking its OK I can live with that.

I have had two regulated PCPs and neither one did this. One was an S500 Carbine with a Lane reg that I installed, set to 120BAR. The other is my HW100 (factory regged) set at 130BAR, and more recently 115BAR. Maybe I just got lucky? I'm far from a "pro tuner" for sure..

That's weird man. I couldn't live with that. I hunt with all of mine and I need the first shot to be on the money.

Hell, my home tuned springers are usually within 1/4" of zero on the first shot. So long as I do my part anyways, LOL.

Another thing may be the barrel or pellets. I had tried some waxy type pellet lube in that S500 once, and it would cause the first couple of shots to be funky like that. I scrubbed the bore real good and switched to lubing with an oil type lube (Ballistol). No more issues. Used it ever since in all my PCPs.

If you are shooting them dry, try scrubbing the bore and trying some lubed pellets. Easy and quick, never know it may help.
