What's Your Ideal .177 Velocity?

[Firewalker]

I am facing issues getting my DAR to not spiral .177 wadcutters and open up group sizes at 10m. What is YOUR ideal velocity for average (8gr?) pellets? 

[K.O.]

is very dependent on each barrel/rifle/pellet... but mostly wad cutters tend to like it down below 650-700 fps...

Thanks Kirby, that will help a lot!

I agree with Kirby's assessment in general but just wanted to add the 9.3gr RWS Supermags are the one I've had the most success with at higher velocities.

For example, I assembled a QB79 HPA conversion that puts them in a dime at 30 yards with a 900fps muzzle velocity. 



I have other guns in which they group even better at more modest velocities but that speed makes a pretty brutal pest control pellet.

They do very well at 12fpe (765fps) from a LW-barreled QB:



It may be that I lucked out with a particularly good batch but they group well from most every .177 gun I own.

Thank you Jason, I'll grab a tin off of Amazon

FWIW - I've settled on roughly 650 fps for wadcutters myself.

Joe, can you speak to the reason why 650 works best for you?
