My 7mm SAUM results *large pics*

[bcsteve]

I bought a stainless Remington 700 bdl in 7mm SAUM last winter from a fellow CGNer, I've got a habit of liking odd or less popular cartridges. I load my
.260 Rem with 120gr TTSX for deer and my .35 Whelen with 225gr TSX for moose so I figure my 7 SAUM will be my "in between, do it all" rifle. My plan is to load it with 150gr TTSX.

I have a bunch of 154gr Hornady IL on hand so I used those to give me an idea of which powder to use with the 150gr TTSX. So here are my results using RL19, RL22, H414, H4350 and H4831sc.

I think RL22 is going to be the winner.

RL19
60gr.......2964fps
60.5gr....2994fps
61gr.......3046fps
61.5gr....3052fps
62gr.......3073fps

RL22

61gr.......3010fps
61.5gr....3059fps
62gr.......3071fps
62.5gr....Could not chamber!?!
63gr......3096fps

H414

55.5gr.......2982fps
56gr..........2956fps
56.5gr.......2967fps
57gr..........2994fps
57.5gr.......2996fps

H4350

54.5gr.......2809fps
55gr..........2828fps
55.5gr.......2858fps
56gr.........2902fps
56.5gr.......2943fps

H4831sc

60.5gr.......2908fps
61gr.........2943fps
61.5gr......2961fps *pressure signs*
62gr.........2966fps *pressure signs*
62.5gr...... Not fired

Well after plugging all your data into my database and tabulating then reading the results I'd say you might want to pursue some RL22 loads. But the computer can be wrong! Good shooting comparison. I compliment you because that's exactly what I do.

great cartridge. I shoot 160gr Accubonds over 66 grs RL25 for 2980 fps (26" Sendero), .........might also be shooting 110gr TTSX @ 3500 fps for closer shots
