Varget, IMR 4064, IMR 4895 or RL15 will get you what you want. Don't work up a load with your cup and core Match Bullet and then just sub that Barns bullet or you could get super high pressure. Barns bullets need to jump a good ways to the lands and use less powder to reach the same velocity and pressure as cup and core bullets. If memory serves me I think Barns states that their bullets should not be seated any closer than 30 thousands to the lands.
