"Tweaking" a load

[chaneylake]

hear ya go Lumpy Grits, sorry for the bad picture quality

same load except .001 +/- neck tension
2 damp patches down the barrel between each shot

3.8 inch outside measurement

200 yards

[Lumpy Grits]

Your on the right track.
Try next .001-.002 NT.
Have you annealed the cases yet? That should be your next step.
Try a "lite" full lenght sizing also.

by "lite" do you mean probably 1/4, 1/2, 3/4 of the case?

I only have 1 expander, it measures .407, every bullet from the PJ mould that I measure is .408

yes, my brass is annealed

[Lumpy Grits]

By "lite", I mean reduce the OD at the cases middle about .002-.003 at most.
Back off the FL die 5-6 full turns off the shell holder and go from there.
FWIW: I use to NS only in both my .45-70 and .45-90. Got talked into trying FL "lite" and have been doing that after the target said it helped.
If you want to try different expander dia. look at Buffallo Arms.

LG, I did a "lite FL" with same load, 2 damp patches, group opened up 1 inch from yesterday, coulda been the finger but I was feeling good about each shot

[Lumpy Grits]

WOW sorry about that.
How different was the weather today that when you fired that group you photo'od
In my .45's, Lite F/L sizing tightened things up.
Try varing the powder load up & down.

Weather was basically the same, my thoughts also in powder change, Cheers

LG, I did another 10 shot group today at 200 yds, 4.08 inches, I did just a hair more on the lite sizing, down another full turn, will probably go up 1.0 gr powder on next 10

Remember. Just do 1 change at a time.
Have you played with different primers?

Going to work with powder first before I make a primer change
