    Hello everyone. New to this site, I hope to stay to give and learn as much as possible.

    Either way I recently bought a set of lee dies for .357 Sig. I was having a little trouble prepping the casings. I got about 50 or so casings deprimed and re-sized using a single stage press then it stopped depriming. I noticed more pressure then usual while pulling on the lever. Then it stopped depriming all together. I Then looked closely at the the casings I already did and noticed they were a little scratched. I then tried running a couple of casings through a .40 die and it seemed to take the primers out but I am unsure of the resizing.

    If anyone has any tips or advice please let me know.


    Thanks in advance.

    The pin on top should be flush with the top of the of the die, if not tap it down and tighten the top nut a little. Also make sure the depriming pin itself is not broken, if so it will need replaced. Hope this helps.

    Yep, the pin may have slid up. I have a set of Hornady dies for the 9mm and if I get a stubborn primer the pin will slide up instead of snap off. Nice, but a pain sometimes if I happens close together. Glad it usually only happens very infrequently.....1 in 250. Usually some type of oddball brass that I got from range pickup. It then gets thrown in the scrap bucket.

    Since we are talking .357 Sig I will throw out a question since The Joker is learning stuff about this caliber and I am trying also. I have heard that you can use .40 S&W brass and just resize them & I have heard they are too short to use. Which is it anyone? I have tons of .40 and someday might use them if possible.

    Using the 40 brass WILL result in the case neck being to short. Do not use 40 cal brass.

    Okay, thanks for the answer. Odd that it is out there that you can use .40 brass, but maybe there are people doing this. Wouldn't be the first time people do something stupid in this world.
