[QUOTE="Lightvarmint, post: 200824"] During the last week, I have been testing some prototype .338 265gr hunting bullets. I am down here at virtual sea level (92' elevation) and our calculated BC using velocity over our Oehler 35P at 600 feet and wound up at a very solid .770......... Similar weighted and shaped bullets indicated .776 with the Oehler at 1204 feet downrange. My question is what would the BC be at 2500, 5000, 7500 and 10000 feet using the same initial velocity and bullet? Or, a better way to ask the question is: What would be the calcualted BC at the above altitudes. Thanks in advance. James [/QUOTE]
