Regarding COL. [snip] What is the maximum on 10MM? I did not see it in SAAMI info either.
• Many pages of load data simply
report what OAL (aka COL) they used for the test. They are not
recommending, merely making a statement. If you'll read Load Data as if it was a Test Report (this is what we did, and this is what happened), then it will make a lot more sense.
• As with all auto pistols, the maximum OAL is that which the
barrel allows. SAAMI may have a number in mind, but that is usually what the
magazine will accept. The realities of bullet-to-barrel fit are what truly determine
YOUR Max OAL. If you have 2 pistols of the same caliber, then one may be more restrictive than the other. In that case you'd want to use the more restrictive of the 2 chambers as the Max for both.
• As with any new caliber or cartridge, you'll want to record this information you generate in your reloading notebook.
Being the most pressing need, CZ's 9mm chamber is what the "How to find Max OAL" article is based upon,
but everything in it applies to auto pistol cartridges of ALL calibers.Hope this helps.
