[QUOTE="entoptics, post: 1894190, member: 104268"] How wide and how long is your barrel? Like a 55 gallon drum? The LabRadar will first pick up the bullet at about 10 yds out, so it should work fine, even if you have to set it off to the side of the barrel. The only issue I could imagine, is if the barrel mutes the blast enough to keep the unit from triggering. As for the down range data, I use it to calculate the B.C. of bullets. You can use the near and far velocity and [URL='http://www.jbmballistics.com/cgi-bin/jbmbcv-5.1.cgi']JBM's Ballistic Calculator[/URL]. You do need to collect relatively precise environmental data (station pressure and temp particularly) for it to be accurate, and you need at least 75 yds of separation between readings. I've confirmed the calculated B.C.s by shooting at distance for a few bullets, and they match up with the real world results pretty well. This is particularly useful for Nosler bullets, which in my experience have significantly inflated B.C. values in the literature. Hornady generally reports very accurate B.C.s, and if anything they tend to come in just a smidge higher than reported. In short, for the setup convenience, the accuracy, and the data, I don't think the LabRadar can be beat. I certainly will never go without one. [/QUOTE]
