Hey Team,
Can anyone tell me what the G7 BC is for the Sierra .308 155gr tipped match king projectiles. I've seen conflicting information online at both 0.229 & 0.237 G7. Does anyone perhaps have the Litz book that could confirm which is correct?

My 308 shoots these at 2865 and I've found the G7 in Strelok at .238 to be spot on, but I've only had them out to 600Y.
My Litz book Ballistic Performance Of Rifle Bullets lists Sierra 155 Tipped Matchking at .238 G7 average from 3000 to 1500FPS.
It also lists a G1 BC of .464 for that bullet.
Neither is probably quite correct, and it would be almost totally impossible to tell the difference as there's about 3cm difference in drop at 600m between the 2 values - pick either or a value halfway in between! Or see if AB has a CDM for it
