[QUOTE="RockyMtnMT, post: 353320, member: 7999"] The ultra mag has free bore. You will not be able to get to the lands. Use the oal that Kirby used. Back off Kirby's load 10% and work your way up. In big cartridges like the rum I work up in 1g increments. Some guys will load 3 or more at each charge weight and shoot for group. I load one at each charge and shoot all at the same target over the chrono watching each one carefully for pressure signs, and the desired velocity. Mean while watching the target to see if there is a grouping with in the load increments. Once I reach the desired velocity or pressure occurs I stop. In the case of pressure, back off a couple grains. Take this info and load several for a group. If it groups well your done. If not tweak the seating depth to improve the group. Hope that was not confusing. Steve PS I know you are close to Kirby, I'm sure he will tell you his methods. [/QUOTE]
