Mid Barrel Tuner install...

[Bluto65]

When do you install & tune a barrel tuner;
1] After you determine what ammo the rifle likes to eat?
2] Ammo does not make a difference, works with all ammo?
3] Just start tuning and shooting?

Please help.

yep

Pick one and start - I try to make sure it will repeat 3 times in different sessions.
Only one change at a time though

Find which ammo provides the best groups CONSISTENTLY. A Tuner will then "fine tune" that load or ammo at a particular distance. A Tuner WILL NOT make a poor shooting ammo shoot all that much better or even close to the potential of your particular rifle's barrel/best ammo combination.

Yes, good ammo. I have ELEY Tenex, Lapua MIDAS and RWS R50.
I got my tuner today from Charles Scott. My rifle will not accept muzzle
tuners. Kinda fat at the muzzle for iron sights dovetail. I am not threading
or turning down my Anschutz 2013 1690 27.5 in barrel to fit a Harrel or Hohen.
It is so heavy in the front that a mid barrel may work just fine.

I tried it out this last Sat and it did fair at 50yds. Avg of 5 shot groups, 5 groups,
was 0.230 lowest was 0.095. Outdoors and some wind at my back, little angled.
Verticals were bad, horizontals not bad.

Verticals indicate tuning needed. Try moving the dampner 1" every 5 rounds until you find the sweet spot. Then fine tune it with 1/4" increments.

I have had great results with a Gene Davis mid barrel tuner (mbt) in conjunction with a Malcolm Drennon muzzle tuner (mt) on my Anschutz. Gene told me to start with just the mbt located 1/2" forward of the stock forend lightly tightened. Shooting groups and moving forward one inch until the groups get round. Fine tune the mbt with smaller movements around the sweet spot until the smallest groups are attained. Then mount the mt and tune to varying ammo speeds with it only. In over six years of using this system I have successfully run ammo as slow as 1035 and as fast as 1090.

I am still trying out ammo. Today I shot some Eley tenex, some RWS R50 and some Wolf.
Surprising, the Wolf shot the best. Next come a try with SK. Hmmm...seems my rifle does not like "gourmet" ammo. This is beginning to be more fun than shooting with my 6mmBRX at 600yds and Yep,
it shoots like a laser. I shot some score targets today with the Wolf and got all 10s and Xs except when the wind got me for a 9. Sure seems that is what the rifle likes, we'll see after more shooting.
Maybe the rifle likes to shoot dirty and I have to alternate ammo, shoot one series with one ammo and then alternate with another ammo and so on. Oh well, this is fun though.

;D Not a surprise that your rifle likes the Wolf ammo, lol. Part of the madness of accuracy work with a .22RF is the ammo any particular firearm likes. To say there is no accounting for taste is an understatement, lol. I once had a .22 that was used in matches that finished at 100 yards. That one taught me two things - although good performance at 50 yards is a good indicator of capability, it is not an ironclad guarantee that it will als be good at 100 yards, it is only a good screening test for the final selection, and sometimes there are some real shockers; going against the grain, this little beast loved a specific lot of Winchester/Western Super-X 40gr high velocity!!

Yep I tried mine at 100yds out of the box with Eley tenex, I had no Wolf. Shot great with out any tuning up. Now I have ELEY tenex, Lapua MIDAS, RWS 50R, WOLF and SK [made by Lapua by the way].

I received my Mid Barrel tuner from Charles Scott and went to a tuning session this morning. A couple of days ago Wolf shot the best out of Eley and Lapua Midas. Today RWR 50R beat out everybody. So now that I had a good ammo I started tuning away, 5 shot groups, RWS 50R.
Didnt try SK though, thats next to do.

Had to start shooting at 8AM, range rules, calm no breeze, 87 degrees [Florida is HOT].

3 - 5 shot groups, no tuner, 0.428, 0.419 and 0.622, RWS 50R
2 - 5 shot groups, Tuner at Muzzle, 0.226 and 0.347, RWS 50R, Muzzle mount seemed to SUCK
so I stopped trying, my barrel has a FAT 1.02 inches diam by 4.5 inchl long, end for Iron Sight
dovetals, I figured it is heavy at the end with that much metal hanging out, no use adding
more.
3 -5 shot groups, tuner a mid barrel about 3 in forward of stock, 0.110, 0.136 and 0.149, RWS 50R

AHA! after some rough twiddling the tuner works, thanks Charles, Stay tuned I will twiddle my tuner some more until the ones become zeros. Have to work quick because the wind starts blowing right
at 9 to 9:30 AM. Cant wait till next week.

Only bad part about fooling around with 22LR is obtaining ammo, "buy it while you can".

My F-Class open is nicer because I make my own 6mmBRX ammo, yeah if I dont run out of VARGET!!

Our range is going to start 22 matches. We usually shoot high power/center fire 600yd one day matches and 2 day tournaments and sometimes we do 300, 500 & 600yd matches, anyway we shoot for score and I assume from talking to the guys the 22 matches will be for score at 50 & 100 yds. I have never shot groups before but I assume shooters that do shoot for group try to get bugholes. What are typical group sizes during a match? At 50yds?
