[QUOTE="Vettepilot, post: 1965491, member: 114372"] OP--> the tips of the bullets almost always vary a bit, even with quality bullets. The important measurement is "Cartridge Base to Ogive", (CBTO), which is from the base of the cartridge to the point on the curve of the bullet that has just achieved bore size. There's tools made to measure this. As mentioned, the COAL, or Cartridge Overall Length is important for magazine fitment, but other than that is not critical as long as it is in the "ball park". Others have also provided very valid points here. Vettepilot [/QUOTE]
