Thread: Magneto V3

Iv had all sorts of weird results with MS attached. Have had it alter group sizes and POI on very heavy barrels.
Now I only use it to get velocity data.
I made the mistake of trying to do a whole load development with it installed once..suffice to say next time out with my new load, and no MS attached did not go well at all. (0.2" group with it on to over an inch with it off??)
It left a bit of a bad taste really...was .338LM as well, must have wasted a good few hundred $ on that exercise.
