In a recent thread this was stated as being something you said ........
Quote " ......... If you shoot loads with different velocities, do you know what I mean about different velocities, not different within the same load, and you have to adjust your tuner to get them to group, your tuner has not stopped the muzzle...in other words,. if you shoot groups with loads of 3300 FPS, then shoot loads of 3350 FPS.....if both will group the same, even though at slightly different places on the target, you have stopped your muzzle...if you have to adjust the tuner to get both loads to group, your muzzle is not stopped.......... "
Is that something you said ?
If so it seems that we are going around in circles. My understanding from what has been written is that with the right weight the proper distance ahead of the muzzle one can make two loads of differing velocities impact at the same place. The logical conclusion of that is that when a load is tuned in between those two velocities the rifle should group well with that load and be rather tolerant of small changes in the loads behaviour due to changes in temperature etc. In essence we'd have created a nice wide load window where accuracy will be at a competitive level and stay there reliably.
The above quote, if true, seems to be off on some tangent to the concept/theory on how muzzle forward tuners work that seems to being talked about.
Can you try and explain what you believe is achievable and the theory behind how that is achieved. Terms like "stopped muzzle" and "parallel node" and such seem to just confuse the issue, people have different ideas about what you are saying.
Does the muzzle stop dead so that a slow bullet will hit lower than a fast bullet or does the crown act as a pivot and the barrel behind moves so as to place a slow shot with a fast shot when the tuner is set up properly ?
What is your take on the comments that the natural vibration patterns of the barrel have no bearing on what is happening since the barrel is forced to vibrate in some other way that is hard to predict by the violence that is happening inside it ?
From a personal viewpoint I have a barrel that I'd be happy to have altered and use for tuner testing but I feel I need to better understand just what I ought to be aiming for to be able to make a vaguely educated guess a sto what tuner to start with and how to go about trying to achieve a nice wide accuracy window.
Many thanks
