I am a rotten shot

Hi guys

Fx Crown .25 green laminate love it. But cannot shoot for toffee.
Any ideas very welcome
today fill 215 bar down to 160 bar
jsb . 25.39 85 yards 
light wind for 3 hours then last hour eased away to nothing
23c -231 ft
chrono readings very avge 890 fps s/d 4.1 e/ s 13. . Over appx 50 shots, sets of 16
me shooting up down left and right no consistency . Same grip front and rear with cheapo bench rest holder. Good scope Mtc 5-;30 viper pro

cleaned barrel yes dirty first 3 to 4 pull throughs dark then pulled clean , balistol 

changed to king Heavy 

Power level Max
816 fps - s/d 3-1 e/s 13 over 27! Shots 
slightly better but high low 2 or 3 touchers left right wind eased right off

shroud in for all this data

do realise I should take stock off and adjust hst fullt in contact then back off as others and Ted have said before. So should be able with heavies to improve the max velocity. 

But must be me . Mustn't it. 
All bolts tight scope and stock. Cheap br touches only edge of woodwork and bottle .
use bubble spirit level adjusted to scope and barrel. 
Trying to blame something else start wondering if scope optically centred. Will read up on that and check.
Honestly my targets look like a 12 bore has been fired.
At 50 metres - 55 yards jsb 25.39 best group ctc 0.71 , mostly all under 1 inch. Poor I know but trying.
don't believe gun at fault, seem to be pretty consistent s/d etc. About 700 shots fired , family weather etc. Since new
reg very steady at 130 

should I take up needlework ,lol

safe shooting
 
Mike hi

Thanks, did try no magazine loading afterwards. Slight improvement. What I did discover was the heavies being slightly longer contact top rotational element on magazine at shot 9 and othes after. Thie pellet is not seating fully and the rear is being shaved on closure. Will carefully check all pellet chambers for incorrect seating. Each pellet needs manual positioning. I will be contacting my dealer . 
Will most certainly investigate those areas.

Many thanks

Anothet Mike

Get fps down to 870 ish. Shoot your group . If its close adjust valve. I shoot impact. Went thru much of the same until i figured it out. You bought an adjustable rifle. Play, Remember speed is not accuracy! I just dont think crown has all the adjustability. trust me. Clean barrel @ 200 rds. please let us know after cleaning,
 
Hi Guys

Thank you for replies

Keyman. Is your impact an x barrel? Only one of those pics loads. The heavies were fired with clean barrel .Weather permittng will shoot again.
re speed. Previous time gun was shooting 25.39's at 890 ish , reduced to power level 4 appx string 870 .Next session same pellet power level unchanged at 4 string dropped to 830 to 840. Put back to 5 again . Only difference I could see was outside temp was 16c and 23c . Bottle stored at appx 16 c. However one thing ar a time.

Sonny. Thanks will try that. 

Hynzie. Will investigate that area too, Michael alluded to that as well. Is your Viper shooting ok?

Having checked cleaning patches from yesterday there are tiny metal flecks apparent. Magazine may be the culprit. Have to wait for a calm day at home range to rezero at 55 yards (50m) single shot loading. As Michael also said will inspect shroud for clipping.

There seems to be different opinions whether to clean every so many rounds or wait for inaccuracy then clean. Some users say they have shot many many rounds with no change . 
Will report back..

Safe shooting
 
Hi
Spent a while testing magazine feed.

Results tested each holder 3 times for each pellet type
Tap= tap magazine lightly
push l = push lightly with pen
push h = push hard with pen
F= will not seat
Kings
Holders
1-6 pass ok
7- pass tap
8 - pass tap
9- push l
10- push l
11-16 pass ok

King Heavy mk1

1-4 pass tap
5 pass push h
6 pass push h
7 Fail jam
8- Fail jam
9- Fail jam
10-16 not tested

KH mk2 batch 2018 year
1-6 pass ok
7- pass l
8- pass l
9- pass h
10 -pass h
11-16 pass

Result Kings be careful loading
". KH mk1 unuesable
". KH mk2 not useable due to bad manufacture of magazine
Magazine discusion with dealer tomorrow who is main importer too.

note. Incorrect seating of pellet causes shaving of base and discharge down barrel of fine material with obvious results.

May not be the only issue of my rotten shooting. More practice more reading and a new brain. Wife showed me where her needle work box was lol.

Yes x barrel. I have magazine loading issues w original mag. Bought new 26 rd. system.

now to hammer adjusting speed. Shoot groups w hammer adjustment. It's almost guaranteed 870ish will deliver best groups. However all guns are different. You will have to work that out. Now adjust valve to custom your shot. When the gun is right you can here the difference. Pffft or light snapinstead of pop. You should get 1/2" @50. I am usally pellet on pellet or @ least touching. Before you worry about long shot make sure you can make the short shot. I spent days @ 50yds to make sure the gun would shoot and then to make sue I, Me could shoot. You're a team! Im shooting reg 130( I th ink you could do less but im shooting well , I'm not changing anything. Don't fix what aint broke) hammer min vale over 4 out. Just turn 1 way or the otheer mark at a time.

Impact is different from Crown,

Hi, yes back to 50 , I agree, yes Ted and others say same thing , harmony .
Will check cliipping too as easy to achieve. 
I shall require another mag , exchanged foc, tested before sending.
You are fortunate that impact has private enterprise alternate mag.
Perchance customer interest will drive a third party better mag, in time.
Sad mag quality inconsistent especially with gun built around the 25.39 , even that doesn't cycle correctly.
