Lots of people ask lots of questions about bullets and their BC. A picture is worth a lot of words (sometimes more than 1,000). Here are some pictures I took of the bullets that I have or will be shooting out of my various .308s and my 6.5x284. Sorry some of the images are not the best.
First are the darts that come from the 6.5x284.
In order from left to right
Sierra 142 gr., Sierra 140, JLK 140, 140 AMAX, 139 Lapua & 123 Lapua.
Next we have the.308 155 class - its easy to see why the Lapua kills teh SMK in BC
In order from left to right 142 SMK from 6.5 to show length difference, 155 Lapua, 155 Carteruccio, 155 SMK
the 175 class
In order from right to left 142 SMK from 6.5 to show length difference, then 175 JLK, 175 SMK,
the 190s
In order from left to right 142 SMK from 6.5 to show length difference, then 190 JLK, 190 SMK,
