consistancy
I have talon ss in 22 but the first 10 shots are irradic before it settles down to great accuracy. Is there any way around this. also I have to re-zero the scope every time I refill the tank. Is this normal.

Hello
I have seen many talon string shots in the web and many of them show that it trend to decrease from the first shot to final shot.
Nevertheless if you fill at 3000 psi some shots may be are below ( because the high pressure close very hard the valve and the hammer hit can not to overcome the stronh from high pressure)
By example this is a string shot with my TALON in .177 with Crosman Premier Heavy 10,5 grains, fill at 2800 psi, the average is 970 fps, and the final pressure after 55 shot is 1600 psi.

AF may just need a regulator to be consistent.
My .22 TSS likes 2500-2700psi. I shoot the crosman domed premier hollow points. They have always worked well for me. My gun used to have problems opening the valve on the first shot after it had been sitting for a while. WOK suggested that I turn up the power wheel…which I did…to 10. That hammer preload setting has eliminated that problem. I also learned not to hold the little gun to tightly. The frame does flex and “gorilla-gripping” the TSS will produce annoying and significant Point Of Impact changes.
A good chronograph really is a necessity for airguns. Without one, you really don’t know what your gun is doing and you might attribute problems to the wrong source. A chronograph is a great tool for learning how to get the most from your airguns. Of course, I always recommend the ProChrono Digital model from Competition Electronics. 😉
The best advice I have heard was from Tofaz…shoot your gun alot. There is no substitute for trigger time.
These guns are just too much fun once you have got yours dialed in. …and for some guys, the dialing in process is just as much fun as the shooting. Good Luck!
2700psi is my sweet spot for my 22SS.. I also shoot .22 Kodiacs. Tophat at .128. Spring set at 11. Get a chrony and experiment.
I started filling to 2000lb and it solved the problem. Thanks guys
IBarberg,
That is the way of many PCP’s.
One of my 25 LBT’s was like that and I just got a BAM 51 in 25 caliber that is the same way. 2200 to 3000 PSI and is shoots for shit, 2200 for 12 to 15 shot it is pretty consistant at 945 FPS.
A lot depends on your valving, my 25 LBT carbine shot well at 2700 PSI with a RL valve stem and Airarcher valve seal and retainer and spring, but with Dayotat’s super valve ist is very accurate with a 3400 PSI fill.
So as the above had stated, find out the pressure it is shooting well at and only fill to that pressure.

Thanks guys. I will try all suggested
X2 all the above and…..
Many have found a 3000 PSI Fill is to much for some pellets. Try 2700, 2200, even 1900 PSI Fill. Many will just waste the 1st shot off target to get the valve re-seared after it has been pushed out of place by a fill adapter.
Don’t fiddle a lot with the scope until you find a good fill pressure for your pellets. On paper is good enough until the erratic POI problem is resolved.
Fill in the info, what psi are you starting at etc,
for the most part after a fill the first 2 or three shots will vary, for tightest groups, i always fire my gun into a stop in the house after a fill to get that out of the way, then after that it is usually good for tightest groups,
like money said, your gun does not like your fill pressure , after it gets rid of some air it gets more consistent,
all things need to be in sink to be most consistent, your tank psi,top hat gap and power wheel, really the easiest way to find this is by filling to say 2700 and shooting a full string thru the chrony at a target, you will see an area where the guns velocity will tighten up. and usually when your velocity shot deviation tightens your accuracy will also.
but for a quick fix , pull your tank when your gun seems to get consistant while shooting after your fill and check the psi in the tank, then just fill to this psi or 50 psi or so above this point.
that will put you in your point where your gun setttled in and started shooting.
first 2 things id do would be to get a chronograph and fill just to where the accuracy gets good.
tophat gap?
power wheel setting?
scope tight?
sumpin aint right…

my talon operates best with less than 3000 psi fills down to 1100-1500.
i keep the PW on 8 and the PS at 9
avg 934 fps…not bad for the .22 crosman premier HP pellets and accuracy is very good…i use open sights, too so it could be better with a scope.
