So I'm just wondering - do cast boolit loads work-harden brass any less than full-power jacketed loads? For comparison, think .260 Remington, 130 gr. cast GC with 15 gr. 2400 vs. 129 gr. Hornady Interlock SP with 44 gr. IMR 4350 behind it - same gun. I've been shooting a lot of cast loads in my .260 Rem and .30-40 Krag and I wonder if I should be annealing every third or fourth loading of cast like I do with jacketed? Thoughts? I'm sure I'm not the first to wonder...
