As soon as I finish setting up a "trust" you'll be hearing from me Zac. Waiting on that crap to get done rather than wait 9 months for every dick and jane in my county/state to sign off on paperwork to get a suppressor. They definitely made it a huge pain in the ass.

Re: Suppressor superiority?

Just dropped off my barrel at Pitchford Custom Guns of Waller, TX. Heard alot of good things about his work. Threading it for a 5/8-24. Also going to have the crown cut to 11 degrees based on his recommendation. What is the importance of the crown angle? Looking at my barrel now you can see the rifling is slightly recessed, then the nose is perfectly flat.

I do not doubt the mystery of barrel harmonics, but a large shift downwards would lead me to believe the weight of the silencer on the end of the barrel is also to blame.</div></div>

The increased "muzzle droop" is what is causing the harmonic shift, along with the increased weight at the muzzle. Part of the reason that barrels oscillate is because the muzzle droops a bit. When the powder is ignited, the pressure causes the barrel to straighten like a bourdon tube, so the muzzle that was once pointing low straightens, and then points up and then points back down and so on.

There are some good explanations on this site:
http://www.varmintal.com/atune.htm

If velocity alone were the factor driving shift, the shift would always be 12:00. Not so. If the weight of the suppressor led to droop causing the shot to move low, it would always shift 6:00. Not so. The shift varies depending on the suppressor and the barrel it is mounted on. In some cases there is almost no shift. In some cases, there can be a lot and it can be up, down, or sideways.

Show me where I said they don't know shit about suppressors. Show me that and I'll cut my dick off and eat it.

With an attitude like that, you won't last long on this site. Listen and learn should be the priority. Lot's of knowledgeable guys at this site contributing postive information, which apparently eludes you. OBTW, SF is top notch quality, performance and service.

Re: Suppressor superiority?

Not really sure who is happy here and who is not...

Stepping back in on the subject of barrel harmonics in general and the effect of adding a suppressor in specific. Whereas it is very true that any thing added to the end of the barrel changes the harmonics, those results vary enormously... all of it AFTER the bullet leaves the rifle. What DOES change? Below...

Lets start here:

Quick Conclusions " From these FEA dynamic pressure calculations, it appears that the <span style="font-weight: bold">recoil and forced deformations </span>are much more important than the natural vibration modes in determining where a barrel is pointing when the bullet exits the muzzle. Then <span style="font-weight: bold">after the bullet exits the muzzle,</span> the rifle barrel vibrates in its various natural frequencies and mode shapes. Put another way, consider a guitar string being plucked. One pulls the string into a position (forced position - "HERE IT IS FOLKS") then <span style="text-decoration: underline">releases</span> it and the string vibrates at is natural frequency. The recoil and bullet motions "pulls" the rifle barrel to a new shape and once the bullet leaves the barrel, then the barrel vibrates. "

Watch all the models here:

Everything one would ever want to know about barrel harmonics..

You still reading? What the hell is the matter with you!
Ok, next we go here and go 1/2 way down the page to "Dynamic Movies of Deformations Amplified 500X"

I have some truck axle bench barrels that simply do not care when I thread on a titanium can that weighs 12ozs.

Now everybody can be unhappy!

Shovel handle? There it is!

Do you prefer mayo or mustard with that?

I hope you're not very hungry because from the tone of your posts, something tells me that it's gonna be cut off before you have a chance to put it in your mouth.

Wait a second aren't you the guy who said a shift should always go 12 o'clock? I must have a poorly designed or poorly built can. Or you are wrong.

Re: Suppressor superiority?

Carter, it doesn't care about deformation flex, change in frequency, heat stringing over time, etc. etc. etc.

All the POI change is can related. In a perfect world, POI shift from boost should always add velocity (12:00), see earlier comments about our imperfect world.

I have no idea about your can, is it not performing?

But...I am always wrong, just ask my wife.
