Hey all,
So probably because I've finished building my 6br, and don't have anything to add to the rifle but still can't leave enough to alone... anyone use barrel tuners? I've seen a few websites extolling their virtues with 22lr. I don't see them in competitions so I assume that means they aren't useful. Anyone have any experience with them?

There are some serious Center Fire Benchrest shooters in the US that use them. Very experienced shooters... and they 'tweak' them in condition changes... but they shoot so much they know what they are doing...

an average guy would be lost...
 
What Dennis said and there is another thought out there.

The other camp feels that the tuner helps give a wider window of tune. Initial load development is done without the tuner on. The tuner is then installed. Shooting in conditions that are very similar that were when load developing, the tuner is used to bring the rifle back in tune and locked down in place never to be moved. When the rifle appears to be going out of tune, it is brought back into tune with powder charge changes. Some even do so with just a slight seating depth changes.

This is done at the short range BR level.
 
Unless you have a particularly cranky barrel, you can load tune using ammo and get the same result.

They are certainly showing up in F class matches but they are rare and are moved even more rarely. The mass at the end of the barrel is really what the point is... acts to change the vibration of the barrel to make it less cranky.

With a cartridge like the 6BR, I really dont see how you can't keep it in tune with proper loading technique

Tuners cannot change the loss of accuracy due to wear.

They are used. See photo below. In general they should not be necessary on a centerfire gun. In a rimfire your ability to adjust velocity of the bullet is very limited. So you essentially adjust the barrel to the velocity of top quality target ammo. In centerfire load development you adjust the velocity to match your gun. That said, they can make the barrel easier to find a sweet spot and potentially make the sweet spot velocity wider. See this article from Varmint Al. If you plan to use it in competition you may want to check the rules... In a 6BR I have found 68 grain Berger Target bullets at 3400 fps are in excellent tune with my barrel.

Jerry that makes sense that they do the same as developing a load - just another way to skin the cat. That would be why they are used with rimfire, it's pretty hard to tune store bought 22lr ammo.

Ron that varmint al page was what started me looking.

In any event, my 6br shoots better then I do (this summer I shot the .5 moa challenge, did .54 moa at 300m 25 shots). I still am developing loads and hitting gophers further than I can see them with the naked eye.

Just was curious if anyone used them.

Cheers

I got a number of us military surplus Remington 40x 308 stocks with them. It is an interesting addition. Used
them for 40x barrelled actions
 
They are being used in SBR , thinking is they do not make a barrel better but instead give a wider tuning window . We tune to conditions throughout the day as they change . Having a more forgiving window is a big plus.
 
I have one on my f-open rifle seems to help tune out a bit of vertical out of my load went for went from 2" to 1" vertical at 600 yards. Saying that, I think they help more on our long barrels once they get over 30" long. Another thing is its just one more thing to tune and when your barrels are only lasting 12-1600 rounds. It's hard to say its worth wasting the barrel life to tune another thing and the extra smithing cost.
