I have been shooting both the 7mm/08 and and 308Winchester here are my suggestions:
7mm/08, LR primers, 120 Barnes Triple shocks, Beginning load 43.gr Varget seated 2.808 COAL I am shooting 46.gr Varget
7mm/08, LR primers 120 Barnes Tripple Shocks beginning load 44.gr IMR-4350 seated 2.808" COAL. I am shooting 45.gr IMR-4350
7mm/08, LR primers, 140 Barnes Tripple shocks beginning load 40.5gr Varget seated 2.808" COAL. I am shooting 40.5gr of Varget
308 Winchester, LR Primers, 140 Barnes Tripple Shocks, beginning load 43.0gr Varget, 2.808"COAL. I am shooting 46.5gr of Varget.
308 Winchester, LR Primers, 140 Barnes Tripple Shocks, beginning load 42.0 gr H-4895, 2.808"COAL. I am shooting 45.5 gr of H-4895.
308 Winchester, LR Primers, 150 Barnes Tripple Shocks, beginning load 42.gr H-4895, 2.808" COAL. I am shooting 45.0gr of H-4895. (Max load in Barnes book it shoots within 20 fps of what is posted velocity and shoots sub .5moa in my gun) I harvested twenty whitetails with this load last year. Complete pass thru on all but one. That bullet went from end to end and mushroomed perfectly. It weighed 127gr when recovered. I shot several deer with this bullet at over 400 yards.
308 Winchester, LR Primers, 150 Barnes Tripple Shocks, Beginning load 44.0gr W-748. 2.808"COAL. I am shooting 46.0gr. Out of 26" AMU Contour, Muller Works 1:10, flat lands, 5R, I am getting sub .3moa, and 3012fps with 6fps ES, and 10 SD. Built this rifle after the deer season but will try it out this fall.
I have found H-4895, RE-15, Tac, H-414, and W-748 all to work well in the 7mm/08 and 308 Win.
Hope this will help you. I just got two pounds of H-414 which is listed in the Barnes load data. Will be testing it this week. It physically looks very similar to W-748.
