I’ll load some up in .2 increments. 3 rounds at a time then load up 4 or 5 more of the best load at the range to see if it repeats and shoot it in the same hole.
I weigh out charges with my sartorius and then put them in vials to bring to the range.Curious... how do you measure powder at the range ?
It all depends on the size of the case.
Example....
300winmag - 0.4 or 0.5 gr increments will hit a node, then I find tune in 0.2 or 0.3 increments.
308 win I start with 0.4 gr, then narrow it down with 0.2
223 - start with 0.3 gr and finish with 0.1 gr
