were is the cheapest place to get some ? any good deals local?
Can someone give me some brands of subsonic and of standard velocity? Like the federal bulk you buy at walmart what is it classified as? The diff between the 2 has me confuse
CCI has Standard Velocity ammo, usually in 100round packs, I haven't seen them in bulk packs.They also have Sub sonic, and a number of brands are sub sonic, I know sportsmans has sub sonic by a couple of different manufactures on the shelf. Yes it costs more.The difference - SV (standard Velocity) usually loaded to around 1100 or so FPS, just under the SOS (speed of sound) which is 1130fps (or 1128fps is more accurate but I have always rounded up for ease of use) at 70 and sea level SV ammo is below the SOS and us subsonic, as the temp drops however, SV can become supersonic... at 32 degrees the SOS is 1088 fps, so a SV will crack.Sub sonic is usually below 1100 fps, so even when it gets cold, they are still sub sonic.Why the big deal about the sound barrier... and we are talking rifles here, because the velocity's don't get up there as much with a shorter barrel pistol... is the transonic zone, the period of time from when the bullet speed drops from supersonic to subsonic. That transition period between the two causes some serious air disturbance around the bullet, causes it to not act areodynamically, and therfore not track along the ballistic path consistently.Also, there the QC (quality control) on standard and sub sonic is higher and more consistent. Try weighing a bunch of bulk pack .22's... you'll get weights all over the place because of light powder, etc... the QC is not there.For a really fun expieriment, take a bulk pack and sort them by weight, shoot the ones that weigh the same in a group, then just grab a handful and shoot a group... want to guess which ones will give you the tighter group?
This is what is confusing me.

That is what has me confused. This is what is confusing me.

-don't let TrooperBrian see it though.
fj why not?
The issue dates back quite a ways. The weak trigger spring breaking under repeated use. The grip safety failing to allow the gun to fire. And the higher sight over bore making rapid sight acquisition take longer than it should. If you don't like my opinion fine, but a quick Google Machine of these issues will turn up hundreds of posts and articles.There's a reason that over 70% of LE agencies choose Glock over others. The insanely steep price difference aside.This sure stirred up a shitstorm. By all means carry, shoot, and trust anything you feel comfortable with and believe in. A petty little comment shouldn't make the lightest difference.

not to complicate things, but also consider the length of the barrel you're shooting out of. for example, would a hypervelocity round stay subsonic if fired from a 4in barrel? as opposed to a 16 inch barrel?
Not to complicate complicated things but but why do high and hypervelocity .22 bullets shoot like poop at 25 yards when they are still super sonic?
My Head just blew up...
