[QUOTE="Barrelnut, post: 2904942, member: 74902"] The cartridge base to ogive (CBTO) of 2.019 does seem short. With my barrels the CBTO with ELdx or Berger bullets is 2.2xx something. So 2.019 is way short. Couple things about the Hornady tools though: 1) The brass case they use for the guage is a piece of unfired brass and it tends to be shorter than SAAMI spec. 2) The part of the tool that measures the actual ogive is not made to very tight tolerances. This means that the diameter of the hole in the aluminum insert can vary greatly and cannot be used to measure against other tools. When using these tools the measurements are only relevant to that specific tool. This means your 2.019 could be someone else's 2.120 or something! A more precise way to get a measurement for your barrel is to use a case that has been fired in that barrel, with a bullet and some blue (or red) Loctite. Put some Loctite inside the neck and barely insert the bullet. Remove the bolt and put the head of the case against the bolt head and slowly insert back into the rifle and let the Loctite setup for 30~60 minutes then extract the case. You will then have a very accurate dummy round and accurate CBOT measurement. It is best to do this by carefully inserting the lip of the cartridge behind the extractor and guiding the bolt and cartridge carefully back into the rifle. It also works easier if you remove the ejector, but not totally necessary. [/QUOTE]
