Simply speaking, the BC refers to how well a bullet navigates gravity, air density, and wind. C. . Spitzer, which means pointed, is a more efficient shape than a round nose or a flat point. The reason the BC for the JLK is. Sep 20, 2006 · Select the type and style of the bullet with the radio buttons and then Carefully measure and enter the values required in the appropriate windows. . . VIDEO TUTORIAL Step 2 Complete the Information Card supplied with your scope and then use this information to fill out the. 404 0. G1 is the old system for measuring BC and is suitable for flat based bullets, but many bullet manufacturers use this coefficient for boat tail bullets as well, so we include the G1 information so that you can directly compare our bullets to their bullets. The G7 is a more consistent system that stays the same over the life of the flight. (the "G7" system uses a reference bullet that is very similar to a modern long range rifle bullet). . If requested, the program will go on to calculate a table of bullet drops, wind drifts, terminal velocities and terminal energies every 50 yards up to 1000 yards, (and. Sep 20, 2006 · Go to the Estimator Select the type and style of the bullet with the radio buttons and then Carefully measure and enter the values required in the appropriate windows. 20101013-Quickstart3 - Environment Tab - G7 Handheld Ballistic. gives us a very small window of the projectile/bullet’s ability to overcome external factors such as wind and gravity. Labels G1, G2, G3, G4, G7 and G18 on the GST Calculation worksheet each have a worksheet attached. For example, if a bullet has a G1 BC of. . This clause confirms facilities for personal hygiene are provided to safeguard from illness caused by infection or contamination. . Only show this user. I used shooters calculator. The G7 Long Range Ballistics Calculator is a FREE online ballistic calculator that will help you understand your external ballistics. . . 271 0. 's for "normal" velocities. The G1 vs G7 value is ultimately dependent on validity and use. C. The G1 standard is an older standard that is not necessarily as accurate of a BC measure for today’s bullets because it does not take into consideration the complete trajectory of the bullet overtime. 000) [0. . . Choose a point D on BA and a point E on CA such that BD = CE = BC. New to me, so I started reading. . The B. . Ballistic Coefficient (B. They provide an excellent introduction to advanced ballistics topics, but without all the tortuous math. . 5 degree boat-tails, with 10 caliber tangent ogive, and are very popular with manufacturers for extremely low-drag bullets.
