[QUOTE="nralifer, post: 2677437, member: 94556"] we calculate the G1 at 0.680 or so. Have to apologize to you. I grabbed the wrong bullet since both look almost the same. The new 150 gr .277 SBD2 prototype is 1.635” long with the tips on both the same 0.250”. Stability for the 150 is 1.43 from a 1:8 and 1.63 from a 1:5 twist barrel at sea level and 59 F assuming a 3000 fps muzzle velocity. [/QUOTE]
