Just loaded some 9mm using the Lyman guide. As a general practice, I load to just under the C.O.L (maximum overall length in the diagram), which is 1.169. My overall length for the loaded cartridge is about 1.166.
However, looking at the data panel for 147 TRN bullets, the O.A.L is show as 1.115-a big difference.
I've been reloading for about 1.5yrs now and adapted the practice of loading to just under C.O.L when I found my 45ACP rounds fed extremely well in a finicky 1911 Gold Cup (ie. no jams or misfeeds in 200 rounds).
Part of my reloading method includes the test that uses a dummy round dropped into the barrel of the gun I'm using to make sure it falls in/out smoothly-in the case of the 9mm it does. I then do an additional test by using a couple of dummy rounds in the magazine of the gun to make sure they chamber smoothly and fully-they do. (Gun is a Beretta 92FS).
My question is related to safety. Should I be following the OAL shown in the Lyman data panel for a particular round religiously, or is my technique of loading to just under the C.O.L and running the dummy round tests a safe practice.
Assume that all rounds are loaded within the Lyman guidelines for the powder used.
Thanks for the help guys.
