Thread: 223 69gr TMK / 77gr TMK damage to projectiles while seating

Once I got to compacting/crushing the ADI 2208 powder near max load I find that the projectiles get ringed/damaged by the seater. I have tried the hornady with amax (secant ogive?) and its not as bad as the Lee die but its still noticable and I need to go hotter still. Looking at the chrono, accuracy and load data chart for both the above projectiles I am going to need a denser powder than 2208 to avoid this damage as I need to be at or around max velocity so what powder is suggested? BM2?
