[QUOTE="shinbone, post: 2535745, member: 15248"] Good suggestion. Thanks. This is the graph of powder vs velocity & group for the 124gn HH and N550. I got a good 5-shot group at 67.7gn (about 0.7") , but couldn't get it to repeat. Bullet jump was .027", neck tension was .0017". I'll next probably find max pressure, then go back and play with bullet jump (i.e. seating depth) at whatever showed the most potential.
