[QUOTE="VinceMule, post: 2849151, member: 122164"] Wachsmann, your post: " I just need to shoot again without the Chrono attached. Generally in the past, this hasn't made a big difference since the barrel is a bull barrel. " barrel harmonics are changed with very tiny adjustments and weight differences. For instance, when I put a tuner on a rifle barrel that is a 1.25" straight barrel blank, I can advance the tuner or retract the tuner adjustment by as little as .005 and see a tremendous difference in how the barrel groups. So, when you add a magneto speed to your barrel, no matter what dia the barrel is, you change the harmonics, but how much is key. I would just chronograph after you have dialed in your load to get the speed. I am normally trying to achieve 3/8" and less groups in my hunting rifles, to put in perspective. [/QUOTE]
