I have been shooting cast bullets from 90 gr upwards of 210 gr in a myrid of 30-06 rifles for many years. Back in the day when we still had 5V targets (I still have a few) we would shoot the NMC with '03s using cast. Found the 311299 would just barely hold sonic to 600 yards. Used a lot of IMR4895 with a dacron filler. Still shoot a lot of cast through my M70 Winchester hunting rifle for practice but mostly shoot cast through my M1903A1 NM Type II. Have been using the NOE 310-165-FN 30 XCB over 20 gr Alliant 2400 (no filler) for 100, 200 and 300 yard shooting. It does very well.
100 yards prone unsupported w/sling. Two sighters w/sight adjustment then 10 for record.
