Impact .25 Accuracy

Birdslayer25 · Dec 13, 2017

50 yards wind left to right. 5-8 mph gust up to 10 or so.
JSB MK1 Heavies!!!
Group on the left is 16 shots
group on the right is another 16 shots
point of aim is the single pellet hole.
I have a 2 .25 barrels. After the first 16 shots I switched to the second barrel and shot 16 more. Thats why theres two POI'S

Interesting, the difference between the two barrels. But both show good groups. Nice shootin'.

Just curious why did you get two barrels in the same caliber?

Birdslayer25 · Dec 14, 2017

Because I'm a total BADA$$ LOL

Friend of mine offered me it for 100 bucks couldn't pass it up. Now I have two

Did some shooting at 120 yards this morning with some light wind.

Green group was at 860 Fps
Orange groups were at 850 Fps
Purple group was at 840 Fps

Yellow group was at 830 Fps

Each square is 1 inch I didn't have time to measure the group. I couldn't find my calipers will measure tonight for ya though.
I wanna say that group is easily 1.25 inches. Theres one clip and I single loaded a few more into that group. I guess 20 to 25 shots. This gun is fantastic!!

I don't see any picrures.
what settings are you using for reg pressure, VS and PW?

1,

It seems the little box's w/out pictures are links, clicking on them works for me.
It is more fun when the pictures are hosted here as I can only open then at home if linked.

Picture is up. Reg pressure almost 120 bar. I have wika gauges there more precise than stock. VS is backed out don't use it. Power is on 2. Shot count 88 shots.

isaacrm1 · Dec 16, 2017

I have a wika gauge in the reg and have been playing using 120 reg, at PW 5, VS 4 I get 877 fps. So I slow down using VS on 2 3/4 and I'm getting 860 average.
Did you leave the VS all the way open?

isaacrm1 · Dec 16, 2017

I also installed Ernest bronze valve seat and the c3 bumper...

isaacrm1 · Dec 16, 2017

I'll post all the speeds I got when I have more time....

Birdslayer25 · Dec 16, 2017

Yeah don't use VS your not gonna get tight string if your using it. You have to tune that thing for tightest shot string or your not gonna have supreme accuracy. Mine is optimal at 830 Fps. The string is very tight it's perfect.

isaacrm1 · Dec 16, 2017

If your reg pressure is 120 your max velocity at PWmax is like 860fps, in order to get it to shoot at 830 you are dialling to PW3. Aren't you having first shoots with some POI shift?
I tough that the best was to Max out the reg pressure to the speed one is looking for....

Maybe the barrel needs to be cleaned

Birdslayer25 · Dec 16, 2017

I've adjusted the screw for my power so many times there no way mine and yours are the same. You need to get it shooting consistent then fine tune it with the screw. It's 1.5mm allen.

Frank hopefully your gun lasts longer than the previous one LOL. The reg on this one is not an easy to fix even for a professional.

I can change every o ring in the gun. The reg on the impact is actually very easy to work on. Don't be scared of your gun bud.
