Shot the M700 LSS 7mm RUM loaded up with the 160 gr AB and Retumbo.
COL was set to fit the magazine, 3.360".
91.0 grs went 3193 fps
92.0 grs went 3215 fps ES 32 SD 16
4 shot group went 1.325" (center diamond)
93.0 grs went 3278 fps ES 39 SD 19
3 shot group went 1.256" (upper right diamond)
94.0 grs went 3319 fps ES 76 SD 31
4 shot group was 1.144", 3 shots are .789" (Lower right diamond, hitting 5 o'clock of the center diamond)
This load has me wondering. I had one low reading, 3281 fps and one flier.
After I shot these groups, I made a few adjustments to get a 100 yd zero and Trevor shot off the remaining loads. He had a nice 1.5" group with all the left over loads.
I am going to reshoot 94.0 grs and also try seating a little deeper to see if I can get the group a little tighter.
This is an impressive round. I shot this rifle last year at 400 yds with the Remington factory 175 gr Swift A-Frames and was hitting a dinner plate size rock. Once I get the 160 gr AB zeroed in at 300 yds, I will see what she will do at 300 yds.
