The Sierra 7755 is a modern low drag .308 155 grain bullet with an acetal resin tip added in an effort to further reduce drag and increase consistency from bullet to bullet. This bullet represents Sierra’s newest 155 grain .308 High Ballistic Coefficient bullet for long range precision shooting. Through independent testing, the Sierra 7755 has been found to have an identical BC to the Sierra 2156, but has a slightly softer tangential ogive shape (hybrid) that may produce good results in your rifle(s) at long range.
Sierra claim G1 Ballistic Coefficients of 0.519 @ 1900 fps and above 0.490 between 1900 fps and 1600 fps 0.420 @ 1600 fps and below.
Independent testing by Brian Litz shows a G7 Ballistic Coefficient of 0.237
