Did a search and didn't find anything I could use. What Redding bushing sizes are you using for best results. Will be starting with the 123's L. With Lapua brass.
I use a .289 bushing for my 260 Rem with Rem brass. The Lapua brass should be about the same thickness. The .289 should get you anywhere from .003"-.005" neck tension. Mine is right at .004" tension.
.288-.287 with ligth turned necks (Lapua brasses)
.290-.289 with no turned necks.
My load by OCW in a CIP chamber print :
- Scenar 123gr Moly and 2,41g of Vihtavuori N540.
- 51,20mm-51,22 from base to tangente (or 69,94mm-69,98mm OAL)
very light tension neck (.001)
bipod and rear bag : 1/2 MOA @ 300m
