[QUOTE="TRexF16, post: 2466748, member: 108912"] Thanks Lou. Am I reading you right that the "they" in your post is Sierra? If so where did you find the information about testing at 2000 FPS? Was it the following from Sierra's site where they list out the BC and velocity ranges? .560 @ 1900 fps and above .530 between 1570 and 1900 fps .485 @ 1570 fps and below I'd say Browning's .617 number looks a little closer to what my eyeball suggests, just comparing the 175 TGK to other bullets. I'm shooting these a little over 2850 FPS in my 8" twist 270 WSM, which is pretty mild but accurate. Thanks again, Rex [/QUOTE]
