With quickload, and a little more info, you can get some good estimates.

Needed info:
col.
Brass length.
Weight of water in a filled fired case. Zero on empty case.
Barrel length.

If you have chrono data, pressure can be more accuratly estimated.

If the quickload software does not have dimensions for that bullet, one can be entered with measurments from a caliper and scale.

Someone might even run the numbers for you if you post enough information.
