    Need 30-06 Ack Imp data

    Looking for some load data for a 30-06 AI using 180gr bullets. I will be using Speer 180 RN and Sierra 180 Spitzer flat based bullets. I have both commercial and military brass. I have AA2520, IMR 4320, IMR 4350, RL-19, IMR 4831 and H-870 powders on the shelf. Any data would sure be helpful...
