Agree on the seating depth / Usable case capacity. The 3.4'ish magazines with the longer bullets, I use 3.37 to 3.38" COAL. Some of the shorter and dependent on nose projection, I am at 3.225". Some of the lighter / shorter ones the rear shank diameter and length limits me from seating longer.
In the 458 Winchester, the 325 grain CEB Safari Solid is my shallowest seated bullet. I have not done the math subtraction. I am guessing there about a 1/4" of bullet in the brass. This is seated about 1/2 way on the 2nd band, allowing 2 full bands inside the brass. This bullet seems very secure without crimping. Though I do a light crimp the a Lee factory crimp die.
