I am relatively new to reloading. So far I have tried 9mm and .38 special and have had good success (fairly accurate, functioned fine, and I still have all my fingers ;-) My next venture in this sport will be .40S&W, as I have a Glock 23 on my shopping list. After reading a bit about the .357sig cartidge, I am intrigued. I might just buy a Lone Wolf conversion barrel and try it out. I hear lot of complaints about the cost of .357sig ammo so I will plan to reload it too. Having never reloaded any non-straight walled cases before, and not having dealt with .357sig at all, is it difficult to reload? Any precautions (outside of ordinary) that I need to heed? Is it hard to find new or once-fired brass? Suggested powders? Any other suggestions / tips / feedback wlecome. Thanks! --- GB!
