[QUOTE="Daryl Licht, post: 1933213, member: 3330"] This round isn't that hard to reload. Since it's bottlenecked it has to be lubed before resizing. I usually lube and resize, then tumble to clean them up. After that, just load them like any other round. There are some things I've found in loading the .357 Sig. 1. Use a suitable bullet. There are a lot out there now that are made for .357 Sig use. Remington makes a 124gr JHP that is available in bulk and works out just fine. 2. Use minimal flare on the case, just enough to get the bullet to start and no more. The short neck needs all the help it can get. I set up the flare by adjusting it in very slowly, and sitting a bullet on top. When the chamfer on the bullet base will just enter the neck that is enough. The "flare" may not even be visible, but this helps with getting all the grip you can with the short neck. Seat the bullets carefully. You may find a short round of brass now and then. 3. Use a powder that fills the case. I like compressed loads because they help prevent bullet setback. Accurate #9 and #7 have been good. Be aware that these will be pretty much full power .357 Sig rounds, but hey, if you're going to load them down you might as well just shoot 9mm. 4. Use a light taper crimp. The Lee dies will do this. Be careful to avoid collapsing the shoulder. Set the crimp to just push that minimal flare back in against the bullet. That sounds like a lot, but it really isn't tough. The .357 Sig round just takes a little getting used to when reloading. My apologies for being long winded. [/QUOTE]
