New Ladder test

[Preda8or]

Ok guys here is another ladder test, 8 twist 22-250 this time with 80gr A-max's bullets H-4350 powder and each test was shot on different days, all three days 1 to 3mph wind mostly calm at 300yds and again no chronograph available. Tell me what my load is?

36.8 grains

I'd say retest the low end of the 36 bracket. I noticed that on one test you test from 35.8 to 37 and on the other one you test from 36 to 37.4 gr.

I think from the targets your nodes are around the low 36.2-4 range. This is where the testing gets harder... do a couple test with .1 grain differences. The smaller cases will show the difference with .1gr changes.

I agree with the above accessement of the right target. Unfortunantly, that isn't confirmed by the left target! Including your first targets, I see no indication of any "sweet spot" or node in your tests thus far.

Perhaps your limited range of charges isn't wide enough to find a node. Or, just as likely, that powder and bullet combo simply isn't working in your rifle.

I doubt that load increments of .1 gr. will help until you get a better grasp on what works.

Hmmmmmm,

Well here goes. First I'd say you're another one who missed the dime;)

Second I"d say your target was at 300 yrds? If it was closer than that I'd say that powder/bullet/seating depth/primer combination isn't the best of matches.

I really couldn't "see" a correlation/repeatability between the two targets to be able to pick the powder weight that would be best.

Just my thoughts.

Good to hear from you again.

Yes 300yrd. Going to try to run another test in the morning

I thought the best way to find seating depth was after you find powder charge?
