Can't find COL on Remington 115gr FMJ RN

I can't find the COL on remington 115gr FMJ RN bullets.

Using Alliant Bullseye powder and Remington casings.

Any help would be appreciated.

The maximum COAL for 9mm Luger is 1.169"

I usually load 115gr FMJ around 1.140"

Yep, 1.135 to 1.150 works well in most guns with 115 grain FMJ/RN bullets.

This is the frustrating thing about my Lyman manual. The only 115gr bullet it shows is a JHP, 1.09oal with 3.5-4.8 Bullseye.

COL or COaL

One of the first things one should learn when reloading is the the COL is gun/barrel/magazine dependent. I pull the barrel and drop a dummy round in. If loading for multiple guns, pull their barrels and check the dummy round in each one. Just as max load is gun/barrel dependent, so it COL. The only "rule" I have is to keep the COL as long as possible and still have firm seating of the bullet and a finished round that feeds and chambers freely.
As Ramshot states in their loading manual:
It is important to note that the SAAMI “COL” values are for the firearms and ammunition manufacturers industry and must
be seen as a guideline only.
The individual reloader is free to adjust this dimension to suit their particular firearm-component-weapon combination.
This parameter is determined by various dimensions such as 1) magazine length (space), 2) freebore-lead dimensions of
the barrel, 3) ogive or profile of the projectile and 4) position of cannelure or crimp groove.
