As per my understanding it’s 1040 fps and it’s a 40 grain bullet.
Experienced folks could enlighten more.

I think .22 LR ammo by KF is standard velocity - should be around 1040 fps with 40 grain round nose.
Only a chronograph will give an idea of actual velocity. I used these rounds around 19-20 years back
I found some boxes had the odd couple of rounds go off with a much louder bang; probably inconsistent propellant feed during manufacture.
Also had a few problems with feed - sometimes would not chamber at all, as the case was oversize.
I trust these problems would be sorted out now. Any forum members with similar problems??
