Precisely. This is why Browning's boss system actually did something (to a degree) it altered the way the barrel flexed and vibrated. An action can have a very similar effect on the way a rifle shoots though. However its a bit harder to tune an action than it is the barrel.

To be clear. You can buy it here.

And you can get the right paperwork to build an SBR. Just make sure you get the paperwork, and get approved. BEFORE you buy the part.

Many people have built SBR's, and many more will. I don't think they are particularly useful, and have no desire to build one, but I figured lets be clear about it. Assuming you live in a state that lets you, and you do the paperwork, these can be legal.

What he said. And I agree 100%, not particularly useful, it does not alter the fact that the pistol has a short barrel and a low power cartridge. But could be a bit of fun! I would probably be inclined to build a good FAL or AR carbine in a short barrel configuration...but thats me. Another good use for all the paperwork would be to get a can instead

While not dependent on the action, if a bullet goes transonic, accuracy will also suffer. Dependent on the ballistic coefficient and weight of the bullet, and velocity of course.

I know about that, but we're talking about harmonics causing a bullet to become unstable after 600 yards and not before. No mention of velocity dropping into the sub sonic speed range. He also says it is the action causing it, not the BC or velocity drop or anything else.

It also doesn't equate with an arrow, he's saying the bow, not the arrow, is the cause.

Barrel harmonics don't so much cause the bullet to be unstable per se. It is more along the lines of repeatable consistent accuracy. Like someone said in one post since this started it really is not a concern for most people, your marksmanship has to be of an exceedingly high standard in order for this to be even noticed in the slightest bit.
Come to think of it...my marksmanship today probably wouldn't be affected by it but back in the day...I noticed these things

However the bow and arrow bit is correct. There is a standard you can achieve with the correct practice that will actually allow you to blame your tools rather than your ability to use them. BC and velocity are totally separate animals in this discussion. They are a factor, yes. But they are not anything to do with this particular thing.

The fun part is showing up with the range with a deadpan expression and explaining it's the latest tacticool addon.

I've been there as far as skill with a bow. Not so much anymore. Rifle marksmanship, I'm working on. I'm just have a problem understanding how one rifle will shoot better to 600 and a different one shooting better past that, with the variable being the action rigidity.

Doesn't make any sense to me either. There are a number of high dollar custom benchrest gun manufacturers, and none of them specify that one is designed for maximum accuracy at 1000 meters, but not at 100 meters, or vice versa. All of them are designed to be accurate by making them as rigid as possible.

I agree. I've read accounts or stories about how a certain gun wasn't accurate at 100 yards, but was at, say, 400. What a bunch of I mean, in order to believe that you'd have to accept the premise that a bullet which was off-the-mark at 100 yards somehow realigned itself between there and 400.

When I first got this


I was a little unsure hwo well a device would work to reduce harmonization but on the Erma, it works incredibly well.

A1fa, that stock makes that a illegal weapon without a tax atamp, if you want a stock for the glock, might as well also buy a supressor and share the tax stamp.
