[QUOTE="Kiwi Greg, post: 1050471, member: 13456"] Mr Schultz :) Your BC data here for the 375 414 SP clearly says BC 1.247, max 3400fps, 1.109 - 2300fps, 0.819 - 1200 fps [URL="http://www.gsgroup.co.za/375414SP256.html"]GS CUSTOM BULLETS - 375414SP256 Technical Data[/URL] This was the reason I got some of your 414SPs to try, which wasn't an easy thing to do. Using the 414 GSC my muzzle velocity was 3140 fps, calculated impact speed for POI at 2065 yards was 1330 fps which works out to an average G1 BC of 0.83 This is a fair way away from the advertised BCs This is why in the video, I was surprised I couldn't see the strikes, I was looking above the 425 CEB impacts when I needed to look 8-9 moa below them. Using the 425 CEB my muzzle velocity was 3140 fps calculated impact speed for POI at 2065 yards was 1590fps which works out to an average G1 BC of 1.03 Incidentally the G1 BC of 1.03 is what CEB advertise their BC as for the 425. CEBs BCs might not be absolutely right/perfect but clearly they are more accurately represented than yours. At a closer range I may have achieved closer results than I did at 2065 yards, but considering the high BC 375 projectiles are for shooting ELR comparing them at 1000-1500 yards is pointless.
