I use Lee Euber's method ...
described in The Benchrest Shooting Primer under the title "Scanning" For The Right Load on pages 197 to 198 which I summarized for my use. I call it:
Working Up a Load …. by Lee Euber
1. Polish bullet with steel wool. Initial seating depth achieved when bullet is marked by all lands. Tony Boyer likes to see a square.
POWDER
2. Load 3 cases in a low grain load. Increase each 3 case load by .5 of a grain, and then shoot. Increase loads until primers show pressure.
3. Identify shots that grouped well, not so good, and then good again.
4. Pick load that shot the best. Load 3 cases with .1 grain less, and 3 with .1 grain more, for another comparison.
5. After picking charge for use, load 30 cases with the same powder charge.
SEATING DEPTH
6. Load the 30 cases in groups of 3, increasing the seating depth from touching the lands to jumping about .040 of an inch, in increments of .005 of an inch.
7. Shoot all 30 rounds without cleaning or clean after each 10.
8. Use ONE fouling shot after each cleaning.
9. Select load that shot best. Load 5 cases with that powder charge and seating depth.
10. Load 10 cases, 5 with seating depth .005 less than benchmark figure and 5 with .005 more.
11. Can compare more than once or change seating depth by .001 or .002.
12. Once you’ve picked the best seating depth, load 15 cases at that depth.
POWDER
13. Check first test by varying charge by .1 grain, for each 5 shot group.
14. Shoot in a medium wind condition, letting the gun do the work.
SEATING DEPTH
15. After picking the best load jumping the lands, compare it with the load that touches. Compare these loads again and again, on different days, in varying conditions, deciding which one is best.
16. If it doesn’t shoot to your satisfaction, restart with a different powder.
NECK TENSION
17. If you decide on the load that puts the bullet in the lands, be sure neck tension is tight enough to hold the bullet uniformly.
18. Its hard work if you want to go to matches and be in contention.
I don't know what others use. I read it. It sounded good so I adopted it. Art

Tune
Get a Tuner, learn how to use it.
I think I sometimes baffle my friends when I tell them I never change neck tension, seating depth, or the load. I have an ideal, or 'pet" combination that seems to work reasonably well in a .237 4-groove Krieger, and I fine tune the set-up with my tuner. You do not know me from Adam, but I have been known to make two bullets touch, on occasion. For the life of me, I don't know why more shooters don't use tuners.
You could try what a VERY well known shooter did for years, with much success. He would shoot only barrels that would shoot his pet load. (He might still be doing this).
I hear shooters say, "I changed my seating depth .005, and the Rifle started shooting. Well, guess what. It the thing is that finiky, it probably won't stay there.
Tuning a Rifle to shoot competitivly, and keeping it there, is one of the Holy Grails of Benchrest. It is something you have to learn, just like reading conditions. On match day, it is usually what separates the shooters at the top of the page, from those at the bottom........jackie
