Hi , I’ve a question, how to get better
Results with the spreads ? Here are my chronographs results :

 

[Jay308]

Chrono looks good to me, the groups could be better.

Is your string name your settings?

 

[bdzjlz]

If you are referring to the standard deviation, it could be pellets varying in weight and head size.

 

[Vetmx]

Your results have little to do with your spreads. Good numbers don’t determine good accuracy. Chasing good numbers just sells pellets.

 

[Chukar60]

Your standard deviation is not bad. As Vetmx said, closing your SD is not necessarily going to shrink your groups. All of your groups except the bottom left look pretty good. The flyer on the bottom left could be from any number of factors like a punched trigger pull, loss of focus at the shot, damaged pellet skirt, errant breeze etc..
I seriously doubt it was caused by deviation in velocity.

Yes

How ?

 

[Trucker3573]

I wouldn’t be highly displeased with a 10 fps ES or those groups . What range were they shot at ?

I tried to lower the speed but it’s still disappointing…

Compared to others with a genuine impact M3 ..

 

[MongooseV8]

Is your Impact factory stock? What is your valve stop set at?

Btw slugs will not ever be as accurate as pellets in most cases. If you can get 1moa with slugs count yourself lucky.
