My old chronograph has gone out. When I started researching new ones I came across this one:

I am going to work up some reloads for a new-to-me Parker GH 28 ga. Apparently this one just velcroes to the barrel and then measures the velocity by the disturbance in the magnetic field it generates (I think).

Thanks!



I am glad to be here.
