PO Ackley said the hottest safe load in the 150grn. 30-06AI was 3150FPS against 3043FPS with conventional loads from the Hodgdon book. He says the advantage with the Ackley is with the larger bullets. With the 180grn bullets the conventional 30-06 with 56 grns of 4350 is 2733 and the Ackley with 4 more grains of powder is 2920. Throat erosion is from heat and blasting the throart with unburned powder.
I reread my thread and can't find where I mentioned any ultra mags.
