Crusty Wrote:...Something I'm still scratching my head over is that I also reset the bullets in a box of Hornady Black ELD-M factory ammo with the seating depth on my die unchanged, and the rounds all came out .010" shorter (OAL and to the ogive) than the rounds I had just loaded with the exact same bullets. I'd be surprised if there was that much variation between runs of these bullets but I'm coming to believe that must be the case.
Morbid curiosity go to me, and I did something like this with American Gunner 123 HPBT ammo, and did them at .005" increments. They were a touch close to my lands so I wanted to see if pushing them back would help.
The 2.242 COAL from factory got slower the shorter I went (stopped at 2.220). Lost about 10 fps for each depth.
