OAL vs. COL
Confused by OAL vs COL
Page 340 Lyman Reloading Book 49th Edition has a picture of a 9x19 cartridge with total length of 1.169".
On page 341 for 115gr Jacketed HP OAL at 1.090"
Hodgdon Reloading Data Center for 115gr JHP COL at 1.169"
My research on the terms:
OAL overall cartridge length
COL cartridge overall length
Are they not the same?
Assuming those two terms are the same, why the difference between Lyman vs Hodgdon for total length for 115gr JHP?
