Interesting., I just did a series starting with 38 grains of IMR 4064 with groups of about 3", expanding to 6" at 40 gr, and back down to 1.5" at 42 grains.
Bullet, NOE 285 grain gas check sized 0.368" with gas check
When I got the 6" group I was about to give up and pull the rest of the loads as I though the lead bullet was failing, apparently not.
