1.175 " OAL, 3.5 gn of alliant bullsey.

My Hornady manual shows a COL of 1.230" for #45100 185gr HP/XTP with a start charge of 4.1gr of Bullseye and a max charge of 5.4gr for the 1.230" COL.
As for crimping, I use the taper crimp to remove the case mouth flare, the cartridge head spaces on the case mouth to much crimp will screw that up. The case mouth of the finished round should measure .469-.471" depending on the bullet diameter and case wall thickness.
