[QUOTE="Lou270, post: 2466712, member: 5352"] I suspect it is because the low velocity they tested (around 2k). If you look at the new 140 6.5 it is same. For rounds where they have higher velocity you see a jump above 2600 fps is published bc. FWIW Browning lists .617 for this same bullets and their ammo is at 2835 fps [/QUOTE]
