9mm OAL question

[Heshin]

I am new to reloading for pistol so I apologize if this has been covered. I have been loading 9mm with 3.8 Titegroup, rainier 124gr HP and a OAL of 1.125. My question is that I have just purchased some rainier 124gr RN, the length of the HP's are .555 and the RN are .595, so do I adjust my OAL or still use 1.125? By the way I am using a Dillon 550 with the Lee deluxe die set. Thanks for your help.

there are several factors that determine cartridge overall length, the length of the bullet's nose being one of the most important. for a discussion of some of these features check out the links below.
