Petrov Posted November 27, 2017 Share Posted November 27, 2017 I was loading some 9mm on my SDB today and took some measurments. My bras was sized a bit oblong 0.371" on the narrow side and 0.374" on the wide side. Is it normal for brass to be a bit oblong like that after sizing. I did this to several different makes of brass with similar results. Link to comment Share on other sites More sharing options...
9x45 Posted November 27, 2017 Share Posted November 27, 2017 Been running a SD since 2001, about 15,000 to 20,000 rounds a year, and all the rounds look like this. It only matters what the finished product is, nothing in-between matters. Never an issue, they all case gage. 125 grain Black and Blue TC HiTek coated over 3.4 grains of TiteGroup at 1.100", goes about 1,050 fps out of a G17 with a BarSto, makes Minor floor.

Hi-Power Jack Posted November 27, 2017 Share Posted November 27, 2017 I've loaded tens of thousands of 9mm (minor and major) loads with my SDB - all fine. You know that the 9mm is a tapered case - not same dimensions all the way up and down? Link to comment Share on other sites More sharing options...
