Thank you..
I used to use a tuner. I tried two barrels with one and two without. The net result after shooting all 4 barrels out was that one barrel with a tuner out agged one barrel without and one without a tuner out agged the other one with a tuner. How big were the differences about 42 thou. In other words not much. Consequently I don't bother with tuners any more.
Attaching tuners is just that attached. They are not a part of the barrel. This essentially adds a sub system to a system that already has many components in it. And thus with that its own set of variables. With each set of variables a event in physics known as moment occurs. Moment can be said to be the product of a force multiplied by the distance between the force and its point of application. When a moment occurs a primary and secondary harmonic will result. I'd sooner just adjust the load parameters to suit the conditions.

This brings up a couple more questions. First, when using a tuner, did you use the tuner itself, change load, or both to maintain tune?
Also, it would seem that the force generated would have to be greater than that of the attachment, to "unload", if you will, creating the second "moment". Second, as I understand it, harmonics travel at the speed of sound. Is it possible for this second moment to occur when the bullet is traveling at roughly three times that speed, and the bullet still be in the barrel when it does?
My experience with tuners has not been that they will improve accuracy potential, but that the tune window becomes wider, which will yield better aggs...unless you are capable of equal or better tuning by traditional methods. Myself, and most of us are not capable of adjusting powder charge/etc.,for tune at that high level, consistently. I admire those of you that can and feel that this is a big factor in what separates the best shooters from the rest of us. Tuners keep me from missing the tune badly, and shooting BIG, and can be adjusted at the bench. That's why I use a tuner. As I read it, you are very proficient in keeping your rifle in tune by traditional methods, or possibly not using a tuner to it's full potential. That's the reason for my first question. All in all, if a shooter never misses the tune, they don't need a tuner, but for those of us that do, the ability to find that tune, at the bench, is worth it, IMHO, particularly if the variable of the attachment creating a second moment is so small that you really found no great difference with or without one. That seems to nullify worrying about the second moment...if it happens while the bullet is still in the barrel. That's the reason for my second question.
Thanks for your time answering, Andy. This is good information that may help with tuner design and attachment, or even not using them at all.--Mike
