Nice buttplug.

>>31527050
Is that a buttplug?

I was thinking more toilet plunger

BassPro sells them.

It's only 12 bucks, there's only one way to find out

Turd hammer?

They work okay.
Takes a bit of experimentation to find the best posistion and it will vary by load.

Someone, and I'm looking at >>31527738, spent waaaaay to much time in /b/

Sometime, it's about actual firearm accessories. Not your fascination with feminine benis and rectal accessories.

DESU, that was the first thing I thought of too - and I'm a total gun guy.

That's kind of ambiguous.

Did you think it was a butt-plug?
If so, doo you ever question why that's the first thing that came to mind?

To me, it looks like some kind of gimmick "100 MPG carburetor" / "as seen on TV" magic bullcrap.

i-is that a foreskin protector?

>>31527050
i use one on my 700 BDL. it adds a dampening position on the barrel (if you have a long barrel) that after you fire, the barrel will vibrate at a specific frequency. assuming the barrel is free floated and your pressure point at the front removed (say you glass bedded it or have an action block or whatever) this will keep your barrel free floated as well as reduce barrel whip which can throw off repeat shots. it has little to no effect on short barrels, or on thick mountain or bull barrels. use them on the thinner or long barrelled actions.

i should mention that this really only affects factory ammunition that isn't tuned to your barrel - if you are using well developed hand loads then this will have nearly no effect.

The principle works, it goes with laws of physics. There are plenty of evidence on damping down SDOF oscillations of vibrating beams with mass dampers.

Mind you, you are going after S-waves (flexural/bending). You can't do anything with P-waves (compression along the beam/barrel axis).

You need to find the highest resonating region of the barrel (somewhere in the middle) and place it there.

That said, I know guys who take a piece of high-damping dense and stiff material, say Blu-tac, wrap a layer of it around the barrel and then clamp it in place with a sleeve. The dense mass layer is now acting as so called "constrained layer".

Remember though that some of the barrels are profiled as thicker around the chamber, and then thin down towards the muzzle. So the region you want is more near the muzzle than the chamber/trunnion.

Those guys explain it pretty well. It adds an adjustable aspect to the barrel harmonics. If you toy around with it enough with a specific load you can improve accuracy a bit, but if you just throw it on the barrel, it's just as likely to decrease accuracy as increase it, and if you're shooting inconsistent ammo it can't fix that.

Real systems aren't as simple as the schematic in >>31531069 is conveying. You need to do some serious dynamic analysis/FEA to determine it.

>>31534367
Ok, lets see your model.

I don't have access to the >$100K software that people use at my work for similar applications. I was stating that it's a complex 'problem', and to try to describe it in the very simple manners that people here have tried to do isn't going to get you accurate answers.

A few details that make >>31531069 invalid are:
-barrel profiles
-semi-rigid attachment to receiver
-dynamic forces as bullet is going down the barrel

I haven't seen Tiborasaurus' video, but from the diagram images I've seen, he's not correct. I'll go watch it sometime.

>>31536346
He probably is correct though since he actually knows his shit. But yeah instead of believing the guy with countless hours and hours of videos with him hitting at long ranges all day long I'll just believe you, anon.
