Strapped my MagnetoSpeed Sporter to the 357 Big Boy X to record some load data.
I was shooting 10 rounds per load and had a little trouble with the bayonet picking up each and every shot.

Re: H012MX 357 Data
I have the Magneto also. What sensitivity setting did you have the unit set to? I usually have mine on H 1 for handgun calibers. However with speeds over 1300 FPS I have to drop down to the Regular or first setting. What Error codes were you getting?
