Folks, I am hoping for clarification regarding establishing OAL for my Savage model 12 .22-250.
Using a Hornady comparator, I have determined the length of the cartridge to the ogive of a Hornaday 55 grain V-max. I then subtracted .025 from that length to establish "jump". A loaded round chambers easily.
The question I have, is that after doing that, the OAL of my round, when measured from the base of the case to the tip of the projectile is quite a bit longer than the OAL listed in my reloading books. Also, I have measured OAL on some factory rounds, and they are quite a bit shorter than the one I have reloaded.
Are factory rounds that much shorter than a round loaded for a specific chamber dimension?
I await the collective wisdom of the reloading gurus to point me in the right direction, or perhaps tell me where to go...
