I am just now getting back in to BR after a 9 year layoff. Bought me a used Grizzly ll LV 6 ppc with a Shilen barrel that Mr. Niblett is re-crowning for me. Mr. Lambert is building me a Shadetree Co-Ax Topped/Witchy Taw hybrid rest. Mr. Harrell is making me a custom F.L. die. So, I am truly happy now, I really thought I was all set. Then tonight I come on here and see this post.

Huh ? Tuners on centerfires ? I understand them somewhat on slow/low pressure rimfires, but CF's ??
.... I am ignorant of most laws of physics so someone explain to me how a centerfire rifle bullet leaves the barrel AFTER all the pressure from the exploding powder has left the barrel ? You know, that pressure that is vibrating the barrel that tuners are supposed to kill at the muzzle....
The same pressure that for the most part will stay behind the bullet shaking the barrel until the bullet is out of the way. The same bullet that once it is out of the way, will not matter to it how much the barrel vibrates behind it...
I am 55 years old and have been shooting guns since I was 8. Somehow I always thought the bullet left the barrel first, with most of the pressure BEHIND it, with some pressure squeezing passed it in the rifling grooves, of course. To me, the bullet should have already left the barrel before any major vibrations resonated the barrel....
It seems that whenever a top grade match barrel is fired, the pressure vibrations will be the same from shot to shot, therefore the neccessity of accurate repetetive hand loads. The top grade barrel will have the same vibrations from shot to shot in theory. ...
Therefore, the barrel should put each round on the paper in the same location because, the internal barrel pressure is the same from shot to shot, making the same vibrations, and the metal in the quality barrel is returning to its same position. To assume that a high pressured centerfire barrel would return to its prior position better, because of a extra weight stuck on the end of it , alludes me. This is my ignorance of physics showing though....
Thinking on this BR shooting now that I am returning to it,whatever happened to watch your flags, tune your loads and let the smoke roll ? With this gadgetry trend in BR going as it is nowadays, the BR firing line is going to look like a science lab rather than a good ole' rifle shooting match. ...
Shooters will be tuning gadgets, reading those wind meters / barometers while at the same time trying to concentrate on getting that last round in the group. While gadget man is doing all of this, the old guy next to him with just a barrel ,scope and action, is concentrating on bucking the one gadget that makes the major difference on the line. Mother Nature's wind. ...
Most top smithed rifles today on the line that are tuned with their sweet load, will shoot in the zeroes all day long in a tunnel. Mother Nature sees to it the shooters on the line with their top equipment, gadgets or not, are all treated equal. Either way, I see that the tenacity of BR shooters to win a match regardless of how much money it requires, is still alive and well. Have fun with all those gadgets
