243 ladder test h4350 help

[rockytop65]

Help me understand what's going on here. I've read we're people says not to shoot paper with a ladder test. But if not an I went by the velocity of the 2 different ones that was close I wouldn't be grouping. So help me understand. It was in the 90s when I shot this. I'm not a seasoned reloader but have been doing it a few years.

if I'm understanding your target ; it looks like shots #2 ,7 , 8 are in the same hole . I'd be looking at # 7 &8 . they are good vertical spread , and good velocity spread . looks like a node to explore .


did you previously shoot a seating depth test ? what distance is this shot from ?

 

[L.Sherm]

To me it looks like you have a lower and upper node. #5 on the lower because it's a flat spot on the velocity and in the middle of a grouping with 4,5 and 6.
Same thing with 10,11 and12 I like #11.
What distance was this shot?

Some more information would be helpful. What range was this shot at? I'm guessing 100 yards. Also what bullet and chronograph are you using?

I wouldn't use paper unless your at 300-600 yds. (600 being optimal). Then I'd shoot the ladder test in pairs: 1,1 2,2 etc; with this method, you have a "second chance" if you pooch one. You'll have a much better idea of your flat spots. good luck.
just my 2c.

I read it as potential node at 1&2, 4&5, 7&8.

I would test 3-5 shot groups in the 7-8 load range to see if ES shrinks and groups hold together. If not, I would search for the seating depth that does both.

I did shoot this test in pairs. I do have a 300 yard range at my house but have to drive little over an hour to the 1000 yard range. I move out to 300 on my seating test.

Oh sorry. I only seen 1-12. a little confused that's all. I didn't see the other shots printed on paper. If your not shooting on the same paper then it's a different method then what I do. All good. Different strokes for different folks. FWIW I'd say 9-10 is your money maker.

1,2,7,8. Nice tight group. But makes zero sense
to me.

Sorry, just looked at this again. First time I had just woke up from my nap. . ES on 7&8 is badass. I'd say pick one of those and enjoy.

If 7&8 are badass, what is 9&10, super badass
