the ammo you select should be tested for accuracy after it goes subsonic.
As always each 22 has its favorite and suprizes can occur. Once you have chrono the load go to the JBM web site and determine the drops for your load
It will be shortly obvious that most scopes can't be elevated enough to go much fast 400
Depending on why you are doing all this gives different paths to rifle and scope selection but this may help.
20 moa mounts will help a lot
Subsonic ammo will not work,
CCI standard velocity gives good results across a broad range of guns
You do not need an expensive 22
Stock must fit is as important as a long range precision rifle
It is easier to read wind with lower power scopes,
On the other hand I can see the trace when using a NF 8x32 on 32
For what I do the Savage Tac 22 in barrel works best
Tried SVT Kimber and other high dollar, but bolt throw not quite what I am looking for
Usually shoot at clay targets to 500 yds. Sometimes if the deflection angle is high the bullet will not break target or if 0 angle punches a small hole
Because the windage is the name of the game, the shooters technique must be good, but more importantly do not chase your shots with corrections. If missed its because the wind changed slightly, shoot again.
Shooting groups at these ranges will only give you the statistics of the wind changes at the time you shoot
There you go Fred...
