9mm OAL for accuracy?

I have a Springfield XDm that I hope to use for CMP matches. Experimenting with some dummy rounds, I found that my max oal is about 1.110" with XTP/HAP and Zero conical JHP before the shoulder hits the lands.  Thought I would try 1.095-1.100" to start, but I'd rather not reinvent the wheel if anyone has the "ideal" oal for this gun. Or is there an ideal distance from the lands that the bullet should be?

1.079 is what fits in my xdm magazines.

I have no issue with the magazines. 1.165" fits in my magazines.

Well, 1.079 is what I use.

Just checked, that's for my 1911
And that's Atlanta Arms dimension on their match 115 ammo.

Ok, thanks Jim

My most accurate load after working up almost a dozen bullets in four different powders was a Hornady 115 grain xtp, 6.0 grains of power pistol, coal of 1.075, and remington primers.
