    Guys, I acquired a bag of once fired 270 brass from a guy I know. Upon examining them I think his rifle has head space issues. The primers are flattened out, and the firing pin indents are cratered. You can actually feel that "stretch" mark right above the case head. It is more prominent on one side than the other. There is some funny looking pitting on the shoulder to neck taper that looks like rust in the chamber to me. I have found two split necks so far after going through about 50 rounds.

    I have since voiced my concerns to him, and asked if it was a new rifle, and he said it was older. I have purchased a 270 field gauge, but have not got back with him yet. These are all once fired Winchester and Federal factory rounds. There are about 200 cases in the bag.

    My wife and I tried to take pictures of these issues, but some of them really didn't show up well. I would like to find somebody knowledgeable to mail a couple cases to, and have them render a professional opinion. I have done such in the past with forum member Zink, but he has not posted in several years. I sent him an email a couple weeks ago, but received no response.

    Any help is greatly appreciated, TIA

    Horse Plains Drifter,

    One of the most difficult trials for a gunsmith is trying to diagnose a problem by remote control whether over the phone, by e-mail or a post on a forum. Far too many problems need an actual hands on look or better hands on with tools and gauges to assess the problem correctly.

    I understand you will send some cases for examination but the best method would be a local gunsmith who could look at both the chamber and the brass while using gauges and a borescope to look at the chamber. This way you get a thorough assessment of the problem(s).

    By your description:
    You can actually feel that "stretch" mark right above the case head.

    Headspace issues would be a good guess.
    You can actually feel that "stretch" mark right above the case head. It is more prominent on one side than the other.

    This is an indication that the chamber is out of round and slightly oversized.
    The primers are flattened out, and the firing pin indents are cratered.

    Aside from a high pressure excursion, headspace could again be the problem. The cratering in general is simply the firing pin hole being too large and allowing the primer to flow into the hole around the firing pin. This is also a potential sign of a headspace problem as the firing pin pushes the case forward in the chamber then the ignition pushes it back against the bolt face.
    These are all once fired Winchester and Federal factory rounds.

    Federal brass is known to be softer than what if generally acceptable for reloadable brass. Winchester is known to have had problems with their brass formulation for both cartridge brass and shotgun shells. I've personally experienced both. Split necks doesn't surprise me on Winchester brass.

    I sincerely suggest a local or reasonably local gunsmith who is qualified to do a hands on examination of the rifle and the brass together.

    Best.
