    ambidexterous1 rather than type it all in again please read my prev. post in this forum title 380 brass thanks jim
     
  4. Sorry, Jim, I didn't see your other post.

    I just went through some of my recently-fired reloads, and found a significant number of cases marked 'FC I assume those are Federal. No sign of Blazer cases.

    It's important to note that all of my .380 cases are more than 15 years old; they're remnants of a long-gone GF who shot a lot of .380. I haven't had any problems or noticed different force required for reloading the FC cases.

    It's possible that Federal has changed their case metallurgy since I got the specimens I've been reloading. These cases measure 0.010 inch wall thickness near the mouth.

    Incidentally, I'm using carbide dies in a Dillon 650.

    If you'd like, I'll send you a dozen or so 'vintage' FC cases, to see if they're easier to load than your cases from (likely) more recent production. To cover all bases, perhaps you'll send me a few of yours to try out. PM me if you want to do this.

    ambidextrous1 I'm going to experiment with annealing a few of these cases just to see they mic. right at 10 thous. at the case mouth as well and they only buckle when you try to flare them the belling itself doe's no damage thanks for the reply I live in big spring about 320 miles east of you jim

    The majority of difference in needed force may be related to the chamber dimensions of the gun they were fired through. Many .380 pistols have generous chamber dimensions that cause excess case swelling.

    I am in the process of resizing a batch of .40 brass. Head stamp does not seem to make a difference. The gun it was fired in does. Glock fired cases are considerably more difficult to resize than S&W or Sig fired cases. The generous dimensions of Glock chambers and the unsupported area at the feed ramp make a difference that is clearly visible to the naked eye.

    If you do not know how to tell the difference between Glock fired brass and others, drop me a PM. Its really pretty easy.

    robocop sizing the brass is not the problem it resizes the same as all the other brands I have on hand the problem comes in when I try to bell the case and flare the mouth a little the expander plug expands it ok but when I push the case into the die a thous. or two to flair the mouth thats when the cases buckle jim and so far it has happened only when using case marked federal 380 auto and the few cases I had of blazer brass allother cases flair fust fine jim

    I have not had any such problems with the assorted range brass (including Federal and Blazer Brass). I am a cheap a$$ and use the expander/funnel that came with the 9mm cartridge conversion for my Dillon. My only problem is occasionally the shell plate does not hold the case perfectly in line with the expander and the opening will catch a case mouth, collapsing the case on one side. Is this what you are seeing?

    Anealing such a small case will be a real PITA.
