I believe over 1000 fps but under 1100 out of my 4" barrel. I'll have to check my records later for sure. No pressure at all. For the Sjhp rem bullets I trimmed the cases back a little short of book so they'd cycle through the marlin. But with the cast performances it's all book. Gentle recoil, less muzzle blast, penetrates like a mofo and accurate to boot. I'm a big big fan. But not out of a jframe. That was less than fun.
