Re: 7WSM Performance
Mine are SAAMI 7 wsm. My load with RL 25 was 60.0 grains, but it has pressure problems in my guns. 66.0 grains of retumbo worked grat in my guns with a vel around 3000 fps. The case will hold 74.0 grains of powder, just touching the bottom of the neck. With 5010 my cases bon't stretch,shoots good, and you can use your brass forever. With 7 wsm you be gaing long enery and the 180's are around .7 B.C.. Shooting paper with .7 BC and 2900 to 3000 fps is nothing to laugh about. it is an accurate well balanced cartidge it is well suited for long range bench rest.
