velocity seems low for long range. nice test, but only 50m.

They are subsonic to avoid the bullet passing through the transonic zone. 22lr destabalize when they go transonic greatly reducing accuracy. All the 22lr competitive shooters I know only shoot subsonic ammo and have massively better results using subsonic ammunition.

This is true. High velocity .22LR ammo slows down enough over 100 yards that it goes sub-sonic on its way and undergoes transonic turbulence which is inimical to accuracy .

I think I read at one point it drops to subsonic around 160 yards to be more specific

thanks for the good explanation, subsonic .22 has been done before. so this is for 100m (LR)?

And beyond (like 200-300). Last year or two 22 shooting has become a thin. it is good for learning longer distance shooting skills like reading wind, etc

Shooting 22 at 300 m is like shooting 300 win mag at a mile

Very interested. Very very interested to find out if my 1913 will like SK long range. Now if someone would bring this ammo into our fine country we could get right down to business. RWS R50 or SK long range ???
wow do I look forward to plus temperatures !
