I normally get bullets weighing in the 178 gr. range from my Lee 170 gr mold. Recently I have been getting equal amounts of bullets weighing 177 gr. range.
I loaded up some test rounds using both the 178 and the 177 weight bullets. on firing them, i found no noticeable difference in the POI on the target. I seperated both weights by 1/2 grains. I.E. 178.0 gr - 178.4 gr. and 178.5 gr -178.9 gr. Did the same for the 177 grain bullets. Saves a lot of remelting the culls.

even 3 or 4 whole grains won't make much of a difference at 100 yards...

unless you are a benchrest shooter, you are over thinking it.
that's a lot of time wasted re-melting bullets over 1 grain of difference.
