Accuracy again

[bravootome]

hello,
maybe someone dig deeper into accuracy and knows more than i do. Again i got accuracy issues, large issues.
TO 7 m i put the bb in same hole every shoot, but when i shoot to 25 m the bb hit somewhere else . I set the scope there but next shoot again someplace else. I test it all day long.....few hundred shoots........ I tried another scope, i checked the barrel to be streight few times. Changed the power. THe bb enters perfectly into the barrel from the breach loading. The barrel is inside other 2 pips so it is solid. Nothing moves. BBs are umarex steel, barrel is airsoft steel..
I dont know what is wrong cuz some time ago it was shooting very well to 40 m or far.

YOu know the satisfaction to hit where you want by one shoot.

A little more info would be helpful, in particular, the valve mechanism. Shot to shot variance in power would not only produce a difference in elevation between shots, but also in windage due to the way a BB travels down a barrel which isn't perfect and through the air.

1st picture is with a tasco scope.
1nd picture is with a buschnell scope.
Both are cheap scopes........


Edit :
1. fixed inside the scope
2. shorten and recrowning the barrel
3. removing a screw used to fix the barrel on th gun. It was strangling.
leaning the barrel after each 3 shoots.

The shoot is by 28-30 m

wait, you are using steel bbs in an airsoft barrel? are the bbs you're using 6mm?

I strongly suggest a rifled barrel. Brass/aluminium airsoft barrel will worn out quick if you're using steel bbs.

The barrel is made out of steel. I payed 25 euro for it. It is illegal to buy rifled barrels (they aren't for sale in my country) Or even to mount by yourself (or shorten the barrel) on a gun the you own....or to exceed the 220 m/s of the projectile...
.........they dont say anything about airsoft guns ( just to be in 6 mm caliber and not to use metal projectiles )
