Good Plan..... I've got loads for Peregrine 140 Gn that are good, so I'll try something based on that. Start slow and work up. There is no information on optimal seating depths on the Lehigh site, so I'll go with the monolithic 'standard' starting jump at 100 thou off the lands and see what that gives. I'm not optimistic given the paucity of manufacturers data but..... worth a try.
