its not really that hard to understand that if you have weight on a barrel especially a thinner barrel your harmonics will change when the weight is taken off, the barrel cant ring at it's natural frequency which you take advantage of when you are "working up a load"
nobody would expect a barrel to perform the same if it was touching somewhere along the barrel and IMO its the same principle
who says that the magnetospeed is put on perfectly at 6 o'clock every time
or that your barrel was clocked properly when fitted
it make sence to me that there could be changes
the straps l am talking about are the original straps that didn't have the nut ect.. it was just a clamp and they all slipped to the point that some of the guys who had them were sending them back for a refund that why they made the change
IMO a clamp would be better but they would have fun trying to produce one size fits all and it is more weight
since l have been using the satterlee technique l do use a pro chrono for load development before doing OCW testing
but before it was after l did load development with OCW testing that l checked speeds, es ect... this always worked out for me
if l were to use the magnetospeed l would be checking for flat spots then taking it off to do OCW group tests then check speed ect after
just how l would use it
