I've done it. Rifle 280AI,27" lilja,1/9 twist, barrel,160gr AB,Fed 215,IMR-7828. I used Nosler data and their start load was
57.5gr/IMR-7828,Fed 210,2836 fps and max was 61.5gr/IMR-7828,3043fps.
I used F-210 to start with 57.5gr /IMR-7827 @2916fps, When I switch to Fed 215 Primer same load...
Finally got around to chono few loads. Rifle, Rem action, 27" Lilja 1/9 twist barrel, Peterson brass, R-26, long throated. I used Nosler data for 175grABLR. My start load was 55.5/R-26 @2715fps, book load was 2697fps and I worked up to max 59.5/R-26 @2941fps. Its hunting rifle so 3 shot...
As I said I just shot few test loads. I don't chrono those loads and also give me chance adjust seating and decide if I want to use Nosler or Peterson brass. Same with Fed 210m or Fed 215. I load at range so doesn't take much to get good test loads to start with.
Finally got some R-26. I loaded up few test loads for 280AI using 175gr ABLR and was about 1" from existing load @ 100yds. Glad Nolser had some loading data.
Hornady X and Sierra Vl Manual have loading data for 308 Norma mag. I think you can get data on line may have to pay for it. Just looking, Hornady has better selection of powder, both use Norma case.
I have 270Wby and on Rem action with Rock Creek 26" barrel. I've had good luck with 150gr ABLR,IMR-7828. I've got couple boxes 165gr ABLR and need some loading data using IMR-7828, maybe QL.
Thanks
This is target we shoot at 100yds The enlarged the target 200,300yds.
