Thread: Supressors.

Yes as a matter of fact. Got a fucking wet arse up the hill this arvo so pulled pin before dark, pub for a few then donga

Now did you read it?
Reduce its stiffness********** Hello, anybody home???
And this is just dumb "Reducing the weight of a barrel by fluting makes a stiffer barrel than reducing the weight by decreasing its diameter." Of course it does. It doesn't make it stiffer, it retains some inherent stiffness from the parent diameter, and this is my point. He does NOT say it's stronger than that original diameter.

I see no were in this were it says the barrel will be stronger or stiffer.

Never have I said anywhere stiffness was ADDED to the barrel, its a comparision between equals (weight for eg)

Reducing the weight of a barrel by fluting makes a stiffer barrel than reducing the weight by decreasing its diameter.

I just went back for a read Spanners and worked out were some of the confusion is coming from.

If you have a barrel at 25mm diameter with whatever sized hole up it, that's how strong it is. Fluting that barrel will not make it stronger as such, or so small an amount that it's not worth worrying about.
You are now talking about weight, so for the same weight you would be slightly larger in diameter of that same barrel. If that was the case then yes it will be stronger cause the extra metal has got to go somewhere.

Or have I still missed it?

there you go

ding!!!

Now we'll get into real life. Show me one person that upsizes their barrel then flutes it. Because that is what you would have to do for your method to work.

You drinking still??

Buy a 10lb blank - decide you want it finished ~4lb
2 options - thin contour or larger contour + fluted

This may be more painful than pulling your own wisdom teeth out...

Well it is raining again, but no.

You won't happen to be saying 4lb has to be 4lb to hold the strength Spanners? I really hope you are. But others buy XXXX rifle then get it fluted, they don't start with a 10lb blank all the time.

Right - time for me to start drinking - you've driven me there........

You have no conception of apple and apples

I'm done.

There is some serious miscommunication in this thread.

Fluting.

If you flute a barrel, it will be less stiff than it was to begin with.


If you have 2 otherwise identical (length, calibre, etc) barrels of the same outside diameter, one fluted and one not fluted, the non-fluted one will be stiffer.

If you have 2 otherwise identical (length, calibre, etc) barrels of the same weight, one fluted and one not, they will be different outside diameters and the fluted one will be stiffer.

Is "stiffness" the single most important factor that makes a barrel 'accurate'? Probably not, given that you can get a sporter contour barrel to shoot extremely well with tuned loads.

Is it possibly better to have a slightly thinner contour non-fluted barrel and not risk inducing stress in the barrel? Don't ask me, I'm not an engineer or a person who gives a damn, I prefer the aesthetic of non-fluted and they work for me so that's what I go with. Also someone wanted to charge me $330 to flute parts of a 14" barrel. I'll go lift a weight instead I think. $330 nearly buys you a years gym membership!

Did you get it after 20seconds, or has it taken a week or so to work it out?

All the wank about the 'barrel opening up when fluted' (I've read up to a couple 1/10s thou?) where no consideration has been taken to the fact that every time a round is fired and the bore heats, the barrel expands.
Get the bore to ~100 C on a 20 deg day ( 1 or 2 shots?) and the bores opened up ~ 0.5 thou on a 338 simply due to expansion.

Blah blah blah - it all gets lost in the noise when the lumps going downrange

No I just didn't have time to post a simple summary earlier in the week. Ironically I'm now frantically loading ammo and decided to do it this morning?
