Question about twist rates & bullets

[L.Sherm]

First I would anneal my brass. Then I would do a ladder test .3 on both sides of your powder charge. Once your settled on the powder charge do a ladder test with seating depth with the 230's and 215's. Forget about 100 yds do your test at 400

Load develop with fireformed brass at 200yds, including full seating testing as recommended by Berger.
