One question, were both shot at the same speed, or did you take more time, slowed down with the muzzle brake? Just wondering, again hard to believe the gases were high enough to control the tip, but I've seen movement on a 22lr, so there is some. I've got two Jerry Miculek compensators, I will be swapping one over to the M&P 15/22 when it comes in next week. This I have t see myself to believe...
