.22lr at 270m

[-Fabien-]

Bonjour guys ;D

Here a video where i shoot my Anshutz 1451 at 270m.
This is kind of shooting i like, don't know how far is the target, don't know the elevation (because this is the first time at this distance), nobody to disturb me...
You can hear the hit at 27sec, 54sec and maybe 1'54.
But i have a question, i use a silencer and subsonic ammo (winchester - 1065fps), WHY do i hear the supersonic crack? "Because the bullet was not subsonic at this time" - pressure and temp...FCUK
Is someone can tell me which ammo is always subsonic? Even with low pressure and high température...

I really had a lot fun shooting this evil stone with my .22lr

If you are hearing the sonic "crack" the round is going supersonic.

Have you chronographed the load?

Any target or std. velocity ammo, "should" be subsonic.

Here another video, .22lr at 350 meters.
I hit the black stone 3 times out of 6 (we can't hear the hit on the video, sorry). Hit at the first, third and fourth shot.
You can see the others impacts in the sand.
The dispersion is not so bad for this little cartridge ;D
Ammunition are RWS HP subsonic.
