First ladder test

Went out this morning and got these for results. Forgot the LabRadar so didn't get any velocity readings. Was at 544 yards again. 2,3,4 look good to me. Now just load some at those charges to see how they group?

1. 70.8
2. 71
3. 71.2
4. 71.4
5. 71.6

I personally would do three at -010, -020, -030, -040. After you find the most accurate of those you can do .005 either side.

I'm currently at 0.005, so should I start there and go to 0.015, etc.?

Still do this at 500+ or should I come back like 300 yards?

I prefer to do seating depth testing at 100 yards because conditions will effect horizontal. I would still do .010 .020 etc but the way you mentioned would work.
 
Finally got out to do some more testing on this today. Used 71.2gr powder.

1. 0.005"
3292
3318
3340
2. 0.015"
Error
3290
3337
3. 0.025"
3347
3347
3305
4. 0.035"
Error
3339
Error



How small of jumps do you do between 0.030"-0.020"?
