There is another factor regarding accuracy that I seemed to have missed here and that is how far off the lands are you seating these bullets. I have found it made a lot of difference in my Tika, with each load change I changed the bullet seating .005 and the group would change. I could give a rip how FAST the bullet is going, I just want it to go the same place as the last one.
