    Question about 9mm (luger)bullet seating.

    I'm new to reloading. I'm setting up my dies, and everything seems to be accurate. Although the finished product has me curious (visually). On the outside of the case, I can see where the brass is beveled out from the bottom of the bullet. In other words, I can see a line around the circumference of the case indicating the depth that the bullet has been set. I would post a pic, but not even sure how to on this forum. Anyway, I was looking at some of my factory ammo and am not seeing anything like this. Is it safe? Is the brass that I have some how too thin? (This is brass (ammo) that I bought, and fired. Never been reloaded. Is it not being resized properly? Or is it completely normal? Like said, I'm new to reloading. Any info would be appreciated. Thx in advance.

    Question about 9mm (luger)bullet seating.

    Not that it's a common thing, there have been times that I've bought ammo and seen what your talking about. I wouldn't say that it's unsafe but if your worried about it I'd take it to my local gun shop and see what they say

    Without seeing it's tough to be sure but it sounds like maybe a sizing issue. If seating the bullet is causing the brass to bulge around the bullet, I'd check your sizing setup because I don't believe that's normal (at least it's not for any of my pistol rounds). If they are too tightly seated it might cause pressure problems.

    If you want to post a picture, upload it to Flickr or Imageshack or any other image hosting website and then just paste the URL into the message with the little button that says "image" in the toolbox above your text window.

    Sounds like you're oversizing your brass (i.e. too much sizing). Back it off a bit and see if it still exists. Good luck.

    That's actually pretty common. I wouldnt worry about it as long as it chambers and feeds like its supposed to.

    HotGuns is right. The bullet will slightly bulge the case where it goes in. Completely normal.
    darbo and BamaT like this.

    Your sizer is sizing the brass smaller than the commercial rounds (not a problem) and then the bullet base expands it case outward as it seats. Not an issue and will help assure a good case/bullet grip.
