Seating depth.

[NF1E]

Working on tuning the seating depth of my 73 gn Berger bullets and precision bolt loads. After finding the powder load, now even more fun. Loading 6 each .010 jamb, touching, .030 off,.070 off and .110 off per the Berger reloading manual. Looking for that .030 - .040 wide sweet spot and then more refining. This is one of the most enjoyable parts of hand loading for me. Nice part of all this is once you change any variable, it back to the beginning. Whatta Hobby!

Hope to get out on the range with my latest seating ladder today. As simple as shooting a couple 3 rnd groups in each seating length might seem, I have always been able to find improvements using this method. Good enough for this old guy anyway. Going from a .010 jamb to a .110 jump usually gives a good indication of a place to start. Whatta Hobby!

you can save yourself a ton of components by just firing 3 of each and make your groups smaller start at 10 off jam then go to 30 then 60 that is three shots each 9 rds total you will know from that where to refine and if you shoot two rounds and you see they are now ging to group don't fire the third round save it  for a fouler or barrel warmer.

Thanks for the suggestion.  I have tried all sorts of different solutions over the last 50 plus years, just thought I would use Berger's idea of two separate 3 shot groups for each depth. No problem using lots of components anyway.  I can always use the trigger exercise. Whatta Hobby!
