g1 is listed .679 and g7 is listed .347 I am coming up with .542 bearing surface using a comparitor bushing that I matched to my throatWhat is the G-1 & G-7 B.C. and length, bearing surface of this long awaited bullet ?
G7 BC is .347, OAL 1.512", BL .536".What is the G-1 & G-7 B.C. and length, bearing surface of this long awaited bullet ?
Compared to the 140 elite hunters, they are long, I was somewhat concerned as well. But then I compare the bearing surface to the 147 eldm, and it seems rather short ha ha!! Also, it seems to take up slightly less powder capacity seated at the same cbto compared to the 147 eld-m, and from what I have seen in one gun, is only loosing 50ish fps to the 147.Quite a long bearing surface, everything else looks great. I wouldn't expect top velocity out this particular bullet though. It would be a great bullet for a 6.5 SST case with it's long 1.512" length and certainly should perform well.
That is encouraging. I don't know how it flies, (accuracy and wind) I will patiently await. Can't shoot 'em in an AR gas gun for performance, but bolt gun accuracy would be interesting.Long bearing surface or not, the reports I've read so far are promising in accuracy and velocity. .260AI hitting 2975 with a 28" barrel at pressure. 6.5 PRC's running up to 3015 in 24" barrels below pressures.
