I've started by getting some OK groups at 100m at different charges, and am now considering fiddling with seating depth.

A good micrometer seating die is a help. I use Redding Competition seaters which adjust to 1 thou. Also good to set your die so that the press cams over a touch, which gives consistent seating depth. Measure the first couple then the odd one as you go.

And measure from the ogive, not the tip, as mentioned above. Much less variation there.

Cheers
