Can anyone tell me where I can get one of these? Hoen? Harrell? They seem to be popular. Anybody use one can attest to their effectiveness?

Thanks
 
They have to be fitted to the end of the barrel and then clamped on. They come with a 3/4 inch bore. I simply made a 3/4 inch aluminum sleeve that fit my tapered barrel and Loctited it in place... then clamped the tuner on. Ugly as sin but they do work well. They will not mark a barrel as the tuner is aluminum.

When ordered from Killough, the site asks for the measurements of your barrel at the muzzle and one inch back of the muzzle.
The one from my Anschutz is now on my BSA after guntech made a bushing.
Part of the trick to get the right combination is to try various ammo from as many lots as you can secure.
Once you have found the best combination, then order a case and then adjust the tuner to that ammo.
When ordering 5, 8 or 10 different lots, make certain your supplier will hold the case for a period of time while you are testing.
It will not make bad ammo much better.
Eley shows a velocity on their boxes. Once you have run out of your case, there may be time saved by ordering lots with similar velocities (5 fps of either side).
That said, I ran 2 lots over the Chrony that had velocities of 1063 and 1062. The 1063 averaged about 9 fps slower and had greater variation. The 1062 was statistically bang on.

This explains a bit of how Eley determines the quality or price of their match grades.

Tenex or 10X as I like to write, is the highest grade of Eley ammo and also the costliest. You would think that this means that all of the top rimfire shooter shoot 10X for competitions. Not true. You will probably see more Eley Match (sometimes called Black Box, because it comes in a black box) at a rimfire competition. So what is the difference? Well, in the manufacturing process there is no difference. They manufacture all of their ammo in lots as described above. Once they have created a lot, they have four different fixed test guns fire that lot in a 50 meter tunnel (to minimize wind). These rifles are all different ages (round counts) with different barrel lengths and chamber specs. If all four guns shoot a lot well (some arbitrarily sized group dimension... an Eley secret), then the lot is labeled 10X. If it shoots well in some of the guns and not others, it is labeled Match. If it does not shoot that well in any of the guns, it is declassified to Eley Team.

I should note that not all of the Team ammo are rejects. Some of it is extras from Match and 10X production... for instance if they made a lot with 5045 bullets, the overfill 45 bullets would go to Team otherwise, they would have a partially full box.

You can also order them directly from Harrels precision. Thats where I got mine. They will ask for the barrel diameter 1 inch back from the end.
 
Do they work, yes!!! Put one on an Anschutz 54 Match with a Lilja barrel, tested a bunch of different lot #'s of Eley Match. Found a lot # that grouped about .5", installed the tuner and dialed it in and ended up with this. 10 shot group at 50 metres measuring .106". Ended up buying 2 cases of that lot#.
 
Wow! 22forever that is nice!!!!
I'm actually interested in putting one of these on a semi auto. Obviously I won't be getting 0.10" groups but it will still help right?
 
I've put one on this 10/22 I built this past winter. I have shot the rifle once at 25 metres without the tuner and and I shot 4 groups (5 shot), .078", .118, .155" and .169". The average of the 4 groups was .154". I have just started shooting again after getting over a shoulder injury so I'll be trying to adjust the tuner with a couple of different lot #'s of Center X at 50 metres.

 
Yes Kilhough's or however you spell it, Dan has them in regularly, but like everything right now, runs threw his shipment quiet fast.
Great company to deal with for the crazy rimfire Nutz:)
I got mine a month ago, but waiting for a friend to make a bushing to go on my threaded muzzle, should work great I hope! Another friend machines brass weights to different length and sizing and has great success with that method.

I just read thru that thread, some really good info I hadn't been able to find. I just about choked reading about the guy with a couple of low fliers every box, exactly what I've noticed on mine. 4 shots touching, then one 1 inch low, exactly 6 oclock. Or 4 shots not touching(more normal, lol), and a low flier obviously different. Not wind, either, although it could be any of the other causes mentioned.
