[QUOTE="JeffVN, post: 390246, member: 2261"] I disagree with Noel. I am extremely skeptical of anyone's ability to generate any useful data in the absence of an end point velocity, at distance. Granted, some of that BC-related information can be obtained by getting a muzzle velocity and then shooting through a chronograph at 100, 200, 500 yards, for example. However, those distancese do not require a trip to the desert with all of its incumbent hassels and equipment. With due respect to all of our proposed shooters, I do not think anyone is capable of putting 5 rounds through a 18" wide and 18" tall triangle at 2,500 yards and NOT shooting the chrograph that is trying to record the information. I hazzard a guess how many rounds you would have to shoot to get 5 rounds to pass though that chronogrph at 2,000 + yards in the moderate gusty winds that prevail on this desert site. More importantly, give the downward angle of the bullets at that distance, a standard chronograph set up is virtually guaranteed not to work, unless you can set it to the proper angle to capture the bullet passing though the trap. That was the benefit to the proposed equipment...a 6 foot tall x 6 foot wide method of capturing velocity data. If we do not have the velocity at distance (at 1,500, 1,800, 2,200, or 2,500 yards) information from a reliable source, then we are left in exactly the same position that we are in now... discussing anticdotal information about the scope elevation that was required to reach a certain distance. No one reading this thread is satisfied with this method. If people want to gather together to shoot long distances in the desert that is one thing; this was supposed to be a scientific bullet BC data generating trip, not simply a desert "fun" shoot. I am not happy that we do not have the equipment we were counting on. I agreed to help with and participate in a BC data gathering test. Unless someone can explain how we can still generate usefull velocity information at distances, I see this as having degenerated to a desert "fun" shoot. JeffVN [/QUOTE]
