[QUOTE="J E Custom, post: 390886, member: 2736"] I went back through my records and found some BCs of other 30 caliber bullets under nearly the same conditions. These are all G1 BCs and I have not calculated the G7 models. 208gr Hornady A max = .594 BC 200gr Accubond = .574 BC 210gr Berger = .614 BC Game king = .509 BC 210gr Match king = .607 BC 200gr Barns xxx = .531 BC These are based on actual range test with similar velocities. (Some were 3200ft/sec+). In order to call it an apples to apples comparison I would have to test them under the same conditions and velocities but these are close. I'm not sure why the Sherman bullets are better but it may have something to do with the rebated boat tail (Less drag). This may not be the most scientific method to find BCs but it is the most reliable to build drop charts. After shooting 3 to5 shots at each distance I measure from the center of each group to the center of the next group for the drop. Being fair to other bullets the performance on game is still out for these bullets. He bonds them and that should make them better for controlled expansion. J E CUSTOM [/QUOTE]
