I see that Butch Lambert at shadetree engineering is going to be making/selling a muzzle device to theoretically place the "anti-node" or dead spot or whatever at the muzzle to diminish verticle disbursion due to velocity variances. Bill Calfee describes it as stopping the muzzle. I have been reading about this over on benchrest central with some skepticism, but hey when Bill Calfee, Jim Borden & Jackie Schmidt and others beleive in it enough to start cutting up barrels, there just might be something to it. I am a newbie to precision shooting and sure that there are folks here that fully comprehend the arguments occuring on that site. I think I have a minimal understanding. I dont guess I have to understand how it works as long as it does work. What do you guys think about these new devices? Do these tuners have a place in the LRH's aresenal? I am thinking that maybe the muzzle could be "stopped" (as described by Calfee) for a known specific distance, but that it would probably be a detriment to accuracy over a broad range of distances. I made the body for one last night and will try and make the weights tonight. If I dont lose a finger on the lathe I should be able to test it next weekend. Most everyone testing them are going to be doing the testing at specific distances. I want to know how they effect POI over a broad range of distances.
