Q:

more ACCURACY issues please help!!!

So I was finally able to get to the range again today at 100 and 50 yards.my accuracy with bags is less then I would expect from a 1700 dollar rifle 2300 dollar system. The rifle has over1400 rounds threw it and it has been tuned by me as some of you know. Just yesterday I reconfirmed my fps here is my results. not only is my accuracy not as good as i thought it would be but the shrould changes the poa by 2 1/2 inches at 100 yards it is not hit, i think it is either due to weight or harmonics of the barrel. i free floated the airtube before also so airtube changes should not be and issue. could my accuracy issues be due to the wrong fps for my gun? could i send my rifle back after this long of having it? should i send it back? i am at a loss with this rifle! i spent just about everything i got to own one and it does nothing that people claim they do!!!!! this gun has brought me more stress then three kids have ever, because at least i can spank children! can’t spank the cricket! well it wouldn’t do me any good!

Okay,

The reason for Free Floating or Loosening the stock bolt(s) is to help minimize POI shifting for those that are not familiar with the practice. As the AT depressurizes from shooting down from a top fill the AT shrinks and contorque with the frame that also holds the barrel and scope rail, this can cause POI shifting to some degree.

If you have Free Floated the AT I just tighten the Stock bolt(s) just firmly and not so tight that your knuckle turn white.
My reason is that before I Free Floated the AT I notice that towards the end of tighten it up the stock bolt had a lot of resistance before the stock finally made full contact with the action.
After Free Floating the AT I notice this was no longer the case and the tightening of the bolt was smooth all the way.
So, the stock must have been binding on the AT prior to the Free Floating.

Before loosening the stock screw by 1/8-1/4 turn CCW would relieve any pressure if any on the AT that made contact with the stock.
So backing out the stock bolt would relieve/minimize this effect, but not as well as Free Floating it in my opinion.

But in the same token if you’re already getting good results with the stock bolt de-tensioning you might think of being happy and satisfy with that. :winkn:

Most of the time it’s best to lightly tighten stock screw. Have had good luck so far. Mine are only tight enough to keep screw from coming loose

When I saw the picture there seems to be no POI shifting… If yes so very small…

I agree with Greg would be better to wait for his JSB pellets arrive. If result will be the same them recheck trigger again and work with the trigger. Mainly do not tighten so much stock screw. It must be tighten very light.

So, i thought if I free floated the airtube that I could tighten the stock screws all the way? And my gun has 2 stock screws.

My 25 sometimes gives me problems , I am always fiddling with it, cleaning it adjusting scope up back to an forward, Its dead on most of the time , but sometimes opens up the group a little , just ordered me a level system, Maybe cant is off a hair, even if the 25 is acting up, I can shoot a sparrow at 48 yards, The gun can anyways.
My 22 is always spot on,? I think the 25 just likes a clean barrel….
Have you got anyone else to set down and shoot your gun a few rounds and see what they get?
It would be pretty cheap[ to send it to an expert on the list to look the gun over and shoot it a few hundred times….
You already have a lot of money invested in it, You may look into it if its still a problem….
Just tossing stuff around, I am sure its been said before…

In the mean while Chad you might want to adjust the trigger pull and location.
I’d double check your trigger location/position, it may be needed to be slightly more forward or back.

Both of my Crickets came a bit to heavy for my likening, especially the second stage pull weight and length.
I like to have a little short slide on mines, it’s just my preference everyone has there own.
I would say that some do like a hair trigger with a very short and quick brake.
If you also, cock it and give the gun a thump here and there to test out the trigger sear engagement positive hold.

if it turns out to be the pellets. How do I buy the right ones?

I’d wait up, JSBs usually it depends seem to change as often as 6 months or as longs as a year.
Even getting them from a different vendor has given me a variation on the same pellets.

~ GKU

That sucks.

I might swap my wifes scope over she has swfa rings also.

Hey GKU could rings with that tape on the inside be causing this? Because that is what I have. Should I swap rings? I was thinking about pulling the tape off and glass bedding the to the scope.

Did you toque the rings if so I don’t think it would.
Rings if you must lapped them.

If your wife scope is already equip with the Picatinny/Weaver one I’d leave em.
If not, I’d swap the rings out.

You also can wait for the pellets, it might save you the set up time with the scope swapping ?
Crappy JSBs, as best as there are in my book they have been know from time to time to kick me right in the nutsacks ! 😆

I can’t give any info on comparing the 2014 JSB lots because I haven’t order any as of yet.
My friend here said he will drop some off for me, someday ?

Well, try the scope swap and the Kings when they arrive, still can’t rule out the JSBs. :winkn:

I like to position my trigger finger on and inhale, exhaling slowly while taking up the first stage at the travel at the same rate as.
At about halfway of full lung out without stopping the exhaling, have the trigger break between heart beats.
The best shots came to me when I knew where my lung was fill to the same point every time on the break, and that’s the hardest part for me. 😳

That’s target shooting for me, hunting is another story.

Thank you so much G. Especially for the hst adjuster.

Does anyone live close to me? Virginia/ north Carolina area. Or is anyone willing to sendme a hi-speed camera and scope mount so that I can post slowmo footage of my shooting.

quote GKU:

HI Chad,

There not to much evidence of a POI shifting, only about 3 clicks but that could just be the slight wind getting the best of you or trigger related.

Questions:
What, if anykind, of trigger work have you done ?
Reason is, I’ve notice that your grouping are more horizontally wider assuming the no wind.
The narrower height is due to the good consistent crony results.

Also what kind of breathing technique do you employ before the shot breaks ?
Which came first for you, powder burning or Airgunning ?

~ GKU

no trigger work yet due to the fact of this gun having the best trigger I have used.

I breath calmly and slowly pull the trigger and pause my breath at almost full exhale then complete my trigger pull.

powder burners came first.

I too thought for a while that it was me. But as of now at 55 yards I can literally watch my pellet inflight to the target and I know that it was of no mistake on my part but still the pellet will go an intire inch of course.
