Speer no longer makes the 400 gr .475 Deep Curls. To be 100 percent honest, the 480 Ruger and 475 Linebaugh really don't produce enough velocity to get the 400 gr Speers to expand. You need at least 1,600 fps to get decent expansion. My 475/350 Mag Competitor can make those bullets expand to catalog quality perfection. The 475 Maximum, 475 JDJ, and 475/500 JDJ should produce similar results.
