Has anyone played with a Harrell tuner on a 20in .920 barrel?
Will a .920 barrel even benefit from a tuner?

If it would benefit a .920 barrel, I was wondering about how much weight one would need.
 
I used an old style Hoehn that wouldn't except weights on a .920 18in barrel on a 10/22, worked quite well. In my opinion the tuner will almost always help, but the best way to find out is to just try.
 
That's just what I did today.. I called Linwood and ordered one, just to see what, or if it would do anything good. I guess I was just looking to see if anyone else tried it, to see if they where happy with there results.

A tuner will help! No extra weight needed, try 113 out, i find there are several sweet spots. If your ever 400 out and not happy with your groups -add about 50-60 grams and go back to 000 and start clicking out again -25 clicks at time does it for me. you will go from all 5 touching to a 3/4" group then back to all 5 touching.. if it is stacking them vertical roll the tuner out (larger number). I had 90 grams extra and 358 clicks, shot just the same as a stock tuner with 113 clicks.

after a few bricks of ammo you will see a pattern and know when your close. I used Wolf Target to learn with. Wolf got good groups but would kick out a flyer ever group. don't pay attention to the one that jumps out. When you find your sweet spot with the tuner go to your best ammo, point of aim will change but for me set the tuner with Wolf and i was within a couple of clicks with Eley 10x jack c
