Now that tuners have become common enough,

and been around enough,

and even won some wood.

I'd like to re-open the topic of "size"....... Have any opinions changed regarding just how much mass one needs to throw around? For instance, is anyone playing with just a couple jamnuts threaded onto the barrel?

A 10 oz ahead of the muzzle will tune any centerfire barrel that is tunable.

A Fudd, for example.

I have been using 4 to 5 ounce tuners on LV and HV profiles ever since they were made legal for competition.

I can tune a barrel very affective with those.

The most important aspect of a tuner is that it is firmly secured to the end of the barrel. Since as little as .005 inch or so movement one way or the other can affect a barrel in extreme accuracy applications, any movement from shot to shot can affect the bullets path.
 
I agree with Jackie,

4-5 oz will tune a Lv-HV just fine. Depending on your tune, .005 movement can be alot of difference. I have seen .001 tighten up the group.

For a UL I settled on a 8oz weight. Just two disc like a Beggs tuner.

To a point, weight is a good thing. It does two things. First, it lowers the frequency more than a light tuner. Lower frequency equals slightly wider tune windows, since frequency is simply a measure of time between two points.

Secondly, it will have more authority which makes it easier to see tune. I call it "talking to ya".

Ultimately though, ya gotta make weight and the gun shouldn't be nose heavy. So, there are trade offs to both.

As to attachment...You really can't tighten one enough to stop all movement at high enough frequencies. Every joint in the system moves. My design takes this inevitable movement into consideration. It's not intended to be mounted solid, by design. It has a few world records and national championships supporting the concept, which manages that very inevitable movement. Tuners are about managing vibration. Not stopping it.
