Thanks for the info Armednfree.. I've measured base-to-ogive and I'm aiming for about .02 of jump to the lands. Those long 75 grain bullets at that seating depth don't come close to fitting in the magazine. One of the drawbacks of using a model 788. I don't mind loading one at a time though. I don't think I want to try seating with the rifle, although it's an interesting idea. It's going to be a coyote and prairie dog rifle (prairie dogs it will be accompanied by a .223 and be used more sparingly for longer range shots).
