I was out today with my 7MM Saum & 300 Saum here are the results. These are with Ruger rifles and 22 inch barrels
7MM Saum 160 Sierra Game King Federal 215 Primer
54.5 Grain 2955 & 2920 FPS
55.5 Grain 2955, 2965, & 2957 FPS
56.5 Grain 3oo5, 3011 & 3008 these grouped right at a inch.
300 Saum 180 Hornady SPire Pt Federal 215 Primer
61.5 Gain 2960, 2955 & 2952 thee shot into .78 inch
62.o Grain 2984, 2977, & 2968
62.5 Grain 2984, 2977, & 2988
63.0 Grain 3022, 3014, & 3017
The 61.5 grain load shot the best group in the 300 and exceeds the 2900 fps that I was looking for. If this will shoot the 180 grand slams anywhere near this it will be my elk load if not I may go with the Hornadys.
The 7MM Saum load of 56.5 grains matches a load I had with H1000 but without compressing the powder.
Nice numbers, your results are pretty consistant with mine. I seamed to gain more with the .300 Saum than I did with the 7mm Saum. Did you notice this with your rifles?
