[QUOTE="abinok, post: 65016, member: 16"] Matt27, I do not know if JLK uses a 43 or not, I would speculate no. They too are a small firm that cannot test all of their bullets. I do know that their BCs are generated with a chronograph, and that their BCs are quite close. Many bullet mfgs are close on their BCs, some are badly over rated.... barnes comes to mind, but anytime that people in the know, people who are respected in the firearms industry are sceptical, it pays to be as well. We could talk for pages and pages over why a given mfg publishes the BCs they do, and all of the variances-gun to gun that can chnge BC, but it all comes down to one thing, the BCs published by firms like Berger, JLK, Lapua, Hornady and especially Sierra have been tested (whether by the company or by independant sources) and can be replicated, within a small degree of variation from gun-to-gun differances by anybody. This testing is done either by radar, or chronograph, not by measuring drop with a tape measure. I have "measured" the BC of the 220SMK at .655, sierra says .629. Their 240gr is published at .711, my "measurment" was exactly that. These were determined by a friends Oehler 35 chronograph, at my home range. The BC quoted to me for the 225gr Wildcat I have ordered is " about .740 or a little better". Published BCs on the 210VLDs from Berger and JLK are .640, and .665 What should be obvious from those numbers is that if Richards numbers are accurate, they will outperform everything on the market. A bullet with BC that rivals the Sierra 240, that can be driven as fast as the Sierra 220 will be nothing short of a miracle, come to think of it, there is another post about these bullets that uses that exact word. All im saying, is there needs to be actual scientific testing done on the BC of these bullets before they are touted as the greatest thing since the stainless steel barrel. [/QUOTE]
