If you read about those 'methods', you will see that they require very good case prep, powder trickling, chrony (good one), etc. I use Lee die for the BO. This is 145gr cast plain base, 2100 fps @ 100 yds., load of H110 from RCBS powder dropper, near max load. BO carbine. Converted 223 brass (range pick-up). NO load development, just below max a bit. Friend wanted to see what my AR10 308W would do @ 200. 165gr cast GCd, NO load development (2400 fps). MOA on steel!
