hello guys, this is my first time on snipers hide and i put this same question on another spot on this site from finding on google then relized i replied to an old topic. anyway i have had my 110 ba 338 LM for about a month now and have realy enjoyed it. been reloading and getting a good load worked up. but i have noticed a little nipple mark on the shoulder of my brass. at first i thought it was just the brass maby, hoping not considering it is nosler brass and they make a good product. put 50 rounds through it and the same mark was on all 50 of them in the same spot. i came out yesterday and was shooting again now that brass is fire formed and used rcbs gold metel bushing die to size neck and bump shoulder back. getting a good group and im happy but now there is another nipple on shoulder of brass in a differant spot horisontaly but same verticaly on brass. i knew it had to be forming to the chamber. called savage and asked if there is soppost to be a small 1mm size indention in chamber, they say look at and call back. anyway there is a little perfectly round indention in chamber that i can see with a flash light. it is exactly at 3 O-clock if you are looking into chamber. it does not seem to be affecting anything other than brass and may mess up my headspace. i have not made up any crazy loads at all. going by the book on my loads other than my over all length b/c the chamber is 3.7295 with sierra 300gr MK and i have my C.O.L. at 3.7200. and retumbo powder under 94gr. do any of you guys know about this and im guessing it is not soppost to be there but if someone with same rifle can look at there camber or there shot brass for me that would be awsome. sorry for the lengthy post. thanks alot
