Errrr..... now I'm confused! There is both a lapua 123gr at .547 BC and also a 108gr with a BC of .478. Are you saying the 123gr is really not 123gr??Jeffvn said:Remember that the Lapua 123 is actually only a 108 grain bullet (the name is confusing - at least it was to me early on), so you can push it significantly faster than the 120-130 grain projectiles at far less pressure. Depending upon the cartridge used (.260 versus teh 6.5x284 vs the 6.5x55) there is a point where the Lapua 123s speed overtakes the higher BC of the heavier bullets (except in the wind).
