Magnetospeed Barrel Mounted Chronograph

I guess part of my problem with your response is your attitude that a good group cannot be achieved with the MagnetoSpeed attached. I am not saying that everyone and every rifle can have good groups with it installed but it is possible and it does happen and by many shooters. SG Jennings post #4 includes pictures of his group with it installed and my post #12 gives the measurements of groups with and without it installed. I guess your comment "Forget it" is pretty conclusive of your opinion on whether it can be done.

Well, I use a chrony for my load development mostly, and one thing you don't want, during a load development, is to have anything strapped on the front tip of your barrel.

I suppose the statement that needs to be made is that the affect to one is not always seen on another. If everyone understands that each rifle may be affected differently - then we're good.
