This is a shot in the dark, but google turned up nothing so thought maybe the experts here knew something I didn't.. I'm having a really hard time being consistent with my calipers measuring case length and bullet OAL. Between not always holding the case perfectly straight, and not always perfectly aligning the projectile tip to the caliper arm, I'm finding myself measuring multiple times and coming up with measurements as much as 0.0050 apart.
With my headspace gauge, that measurement is always dead-on, because the cartridge is always consistently held. Is there a simliar "holder" out there that clamps onto caliper arms for empty brass and assembled ammo? Even just something that makes the caliper arms wider, giving me more space to hold the bottom of my cartridge flat against them would do.
