Profit share came in! After shooting my chrono last month oops:less said the better on that) I am in the market for a new one. I have the funds for the Magnetospeed V3 or the Labradar. I would like your opinion one one or the other considering: 1.) I know the Magnetospeed changes POI. I don't intend to do work up with it attached, I just want velocity for the ballistics table and final SD\ES of the load. I realize this would mean 10 or more shots. 2.) I work a lot with .223 and .20 caliber. 3.) I shoot from -20 to 100 degrees - weather doesn't stop me except for blowing snow and pouring rain. 4.) A couple of my rifles (not .223 or .20 ...) have very large muzzle brakes (distance and placement of the chrono). Please give me your thoughts. I am going to pick one up, but I would like to hear about your experience with them - especially if you have used both!
