Guys can you clarify on why SV would be better than HV?
It seems counterintuitive to me, assuming HV packs more bang and works the action stronger (?)
As I said before, I'm keen to learn more about 22LR.
The theory behind it is this:
High/Hyper Velocity ammo is supersonic. Going through the sound barrier makes the bullet wobble a little. Especially when the bullet slows down below the sound barrier. There is also a theory that the shock wave from the bullet hitting the sound barrier catches up to the slowing bullet and also creates some wobble. This wobble can throw accuracy off. Because of this wobble, SV, match and target ammo is loaded subsonic. They don't go through the sound barrier, so don't have the wobble. From this perspective, SV, target and match ammo is more accurate. Also, there are different bullets, lube and powders used between them all. Plus with match ammo the consumer demands a higher level of consistency and reliability. I am sure the tolerances are set a little differently (tighter?) for target/match ammo.
Also, 22s are some of the pickiest guns on the face of the earth. They like (and also don't like) specific kinds of ammo. The only way to find out which is to shoot different brands. Generally speaking you will find that SV, target and match ammo will shoot better (Some significantly better) than any high/hyper velocity ammo does.
Back in the old days (before high and hyper velocity ammo) all .22 was SV. Target loads were made to tighter, more consistent tolerances (however that was done?). But as it turned out, just like today's CCI SV is a bargain target load so was the Remington green box SV ammo. That was the go to target load when you didn't want to spend a fortune on target/match ammo. But watch out if you own a semi auto .22 from the 50's/60's or earlier as they were designed for SV ammo only since HV ammo was not manufactured yet. And a steady diet of HV ammo in a gun only designed for SV can tear a gun apart.
