Well I ordered my tuner last week from Harrells precision and hadnt heard back so I thought I would call today. It shipped on the 26th before they even had payment. They told me to ship a check when I got it. But we decided to do CC payment due to being easier with me being in Canada.

Super great guys to deal with.

TDC, here is a picture of my SUHL 150 with a Harrel's tuner on the barrel. [also a picture of 5 - 5 shot groups at 50 meters, avg size .1996"]
A tuner is to help one tighten his groups...can be adjusted for different ammo.

with a 1" OD bull barrel do you still get all that wave action on the barrel?

would putting a tuner on a semi auto have the same results?

are these tuners threaded the same as comps and brakes?

1/2 28 TPI?
 


This is a Harrell tuner. Just happened to have it off as I have the target sights on my Anschutz.
The barrel is measured at the muzzle and 1" back from the muzzle.
The supplier then drills the tuner to those dimensions.
When installed on the muzzle, there are two set screws that clamp the tuner to the barrel.
There is a scale on the tuner starting at "0" and another scale on the bell from 0 - 25.
Four rotations of the bell would move along the tuner scale to 1 which would equate to 100. The picture shows a setting of about 341.
All ammunition will be different but with 5 different lots you would find the one that performs best without the tuner then with the tuner installed, work towards the setting found to be best.
Everyone uses them slightly different. Our premier shooter in BR 50 at Mission finds the best lot, then installs the tuner and leaves it set at "0".
I start at "0", fire 5 shots, then keep advancing one revolution at a time until a sweet spot appears and then disappears. Then start working backwards until a spot is found with one of the revolutions and honing in within that one revolution.
Then you want to buy a case of that ammo . . .
 
would be interested on putting one of these on my gun i put together last year.
but i have a threaded barrel.
do they make these things to go onto threaded barrels?
 
Well my tuner showed today a week from the time it shipped. Not bad Ive had stuff take longer from across Canada and this had to come over the border.

As far as for a threaded barrel I dont think Harrells make a threaded one but someone else might but the Harrells will still work.

I wont get a chance to try mine until the weather warms up a bit. I still got to get the front screws out for the front sight base on the barrel and they are in there tight.
 
One of our shooters had a gunsmith put an aluminum cap to the dimensions of his old barrel onto his new barrel so the tuner could be attached.
Since a threaded barrel generally has a cap, why not have a tuner fitted to the cap? If the cap was a straight 0.75", then the tuner would fit without being drilled.
In conversation with another shooter who has built a 10-22. He is going to attach the tuner to the 10-22. It still has to be tested.

Where there is a will there is a way . . . or where there is a will there is a lawyer!
 
im thinking i would like to try one of these on the 10/22 i made.
im running a Dlask 18.5" extreem bull on it with his compensator on it.
im guessing it could just fit over the comp?
