The barrel tuner works, but it is not a stand alone piece but more as a part of a system that you need preparations first. You need to do the initial cleaning = tuning any possible flaws from the system and when you got it to a perfection (you think) and only then you mount it...it will be an eye opener.

Lets assume that you did all your home work with the gun, everything is perfectly tuned to a given projectile that is a closest match to the barrel. And you using a tripod to shoot the 100 = pfuuuufffff everything falls apart. For a real BR or longer ranges precision shooting a bipod is a limiting factor and you need a more precise rest, a one piece or two piece rest. And when you have everything on the pile we can say wooow, this thing works.

I got the barrel tuner integrated into a shroud, it has an internal - backward blowing air stripper as a part of a adjustable flange. I like it, but I didn't got to my 95% yet. Shopping now for a one-piece rest either to buy or to make.

p.s. that integrated air stripper .... :) when I remove the shroud from the barrel, woow to see what the fine lead dust looks like stick to the barrel....like a thick grey (gray) grease.

Over three different sessions I have shot 5-6 shot groups and adjusted between each group. The first two sessions were gross adjustments, turning the dial 1/8th of a rotation each time at major sub-tensions. Those two sessions showed a repeating pattern of tightening and loosening groups. I chose the first major shrinkage as my focal point, as it is closest to the fully extended length and therefore easier to re-set at the base line "zero".

Today I started examined the prior targets, and determined that between 6 and 7 major ticks from zero was the first best area to examine. I shot groups from 5.0 to 8.0 turns and then shot from 8.0.to 5.0 turns, making a minor tick adjustment between each group. There was some wind, even so, there was a repeating and noticable trend in the group size. I will repeat the test again on a different day to normalize the data. Note, I am not a super shooter and I make no claims to be otherwise.

Does the threaded weighted adjuster make a difference in how MY gun shoots?? Yep, it sure does. Does it magically make all my pellets go perfectly where I want them?? Of course not!

I expect the tuner will eventually help my tune to reach a plateau, where most errors can then be traced to the fool on the trigger rather than the tool in his hands. Take out one variable at a time.

With my FX Maverick .22 Compact, I have "discovered" exactly who the fool on the trigger is..............Not many excuses are valid if you miss with the right tune.
