    Anyone seen this before?

    Has anyone seen this before? 95gr sst for my 243. Everytime I go to seat the bullet the die takes a chunk of the copper jacket and leaves a ring. Tried another die and it did the same to the bullet.

    Any help would be appreciated

    Cheers

    yip...its where die contacts projectile,only get it with soft projectiles...try champhering cases a little bit more so they slip in like a well greased prcik up a slack fnany....it does make a difference to ease of loading...and the ring WONT EFFECT PROJECTILES PREFORMANCE.

    Virgin brass is quite often in need of trimming and chamfering.

    Greetings All,
    My standard prep for new brass is to lightly lubricate the inside of the neck with a strip of Chux cloth wrapped around an old bore brush and run the expander button in and out of the case mouth. There is no need to neck size and new cases should definitely not be full length sized unless they won't chamber. A chamfer inside and out completes the process. Cases are full length sized as part of their final forming process and the necks are not expanded so the necks usually are concentric with the case body. Full length resizing unfired cases can do more damage than good.
    Regards Grandpamac.

    I always got that mark on projectile when loading SSTs for both .308 and .270.

    And if it's not fully relaxed (annealed) it needs lubed

    You could just throw the SSt's away and get some good bullets

    The ring is caused by the seating stem inside the die. The shape of the vld bullets with long noses don't conform to the standard (old) angle in the stem and if using hornady dies you can get a new vld stem for all those nice new pointy bullets! Another cure is to take the stem out, coat a bullet in grinding paste in a drill then use it to grind out the sharp edge it the stem.
