Polygonal rifling! Yay or nay?

Actually I have been thinking of going back to testing it. Its a shame that I haven't because I felt good about the barrel.

Let me ask in a different direction...

To all that have given great information, your input is greatly appreciated...

For all that have used polygonal barrels*.
Would you got back and replace with the same?
 
The "internet says" in summary: polygonal barrels have longer barrel life, less accuracy, and easier to clean than conventional rifled barrels.

Yes I agree".
I read that before posting this..

But I am a human that rather listen to other humans speak or post their own experiences.

Thanks.....

And NO! I am not being stubborn.....
Just want first hand experience on the subject.

I have a BHW 24" 3 groove polygonal barrel on a AR15 chambered in 6x45
Accuracy is great, clean up is a breeze.
Would I put 1 on a competition rifle?
Couldn't say for sure
Hope this helps

I don't compete,..but I do like accuracy and consistency..

Thanks for posting. I see you make wonderful stock's.
May give you call sometime and chew the fat for a while..
I would love a good hand made stock for this build.

I don't make the stocks, I just make them pretty.
I wouldn't hesitate to buy another poly barrel for a hunting plinking rifle

I can not prove nor disprove they clean clean easier, just know it they shot for two of us if that helped

I say my ratchet cleaned easier than the Kreiger on my previous upper.

I also have a polygonal .243 gas gun from Black Hole Weaponry that shoots better than a big gas gun should and also cleans easy.
 
I have/ had two. An HK 300 with the factory polygonal rifled barrel and legendary accuracy shown by that rifle. I had an AR-10T (LW)in .308, 1/11.25. That rifle was one of the most accurate rifles I’ve ever owned. Easy to clean as well. I wouldnt hesitate to buy a Lothar Walther polygon tube for a custom long gun hunting rig. I cant comment on BR use.

Sorry to beat an old horse".
I would like to know personal opinion from actual users of polygonal barrels.
It seemed that it was a rave 10 years or so.
Let me know your thoughts.
Your experiences.

Is it beneficial?.
I am in the search for a new barrel, and would like to try something different.

Thanks in advance.

As others have mentioned here, not all polygons are the same.

Some "ratchet" just means the lands are slanted on one side, but edges are still sharp.

The only true polygon I've owned is BHW's "Caudle". I have Pac-Nors that look to have rounded edges through a bore scope. I consider both of these true polygon, and both will shoot sub. 0.25 moa, better than I can shoot.

There are three other advantages of true polygons that have not been mentioned. The smoother land edges create a better gas seal, which accounts for their higher velocity. There is also less bullet jacket deformation, as they don't "engrave" the jacket like standard rifling. And lastly, they create less friction, reducing both barrel and jacket heating.

Having experienced the many advantages first hand, I personally would never buy anything other than polygon. FYI, Pac Nor said 90% of their sales are polygon.

This is real experience information.
Thank you sir,.. much appreciated!
 
I tried a couple of Shilen DGA polygon barrels, back in the late 70's. They were not great and didn't clean well. One worked quite well as a cast bullet barrel. I chambered an H-K barrel to 22 BR which shot pretty well but the platform wasn't good enough to prove the barrel. I don't know what steel it was, but it was the toughest barrel I ever turned. WH
