From the left, 25 WSSM empty, formed 358 WSSM, 308 Win and 300 WSM

The 358 WSSM is formed by necking 243 or 25 WSSM up to 35 caliber. The load I use is a 200gr TTSX on top of 48gr of H4895 lit by a WLR primer. It clocks 2575fps out of the 22" barrel. I can get them to go faster but the above load averages under .75MOA out to 250yds.

The rifle is a Mark Penrod built Model 70 WSSM action with a Lilja No 5, 1-12 twist sitting in a B&C Coyote Lite stock. The scope is a Leupold VX-6 2-12X42 sitting in Talleys.
