Before you sort hundreds of bullets by base to Ogive, test the DIAMETER of your bullet lots. Not all 6mm bullets are exactly 0.243“ in diameter.
Bullet “girth” is something few shooters even think about. However, all my best barrels showed preferences. One barrel really preferred skinny 6mm bullets that were measuring 0.2427-28. Another barrel shot best with some fatties that were running 0.2435. The diameter can vary based on the age/wear of the bullet manufacturing tools, or by design.
