Can't post pics, the digital camera is at the cottage but I'll give you the dimensions. This brass is a mix of Federal, Win, and some Rem. The Federal brass when reloaded will case gauge easily but the rest only about half will. Going by my Lyman book, I'm meeting the .473" at the crimp, and the .476" at the base but I get a small increase in between. You can't see it with your eyes but the calipers are measuring .477-.479" just above the base. My overall length is 1.245, under the 1.275 max.
I'm using Excel 200 grn LSWC (.451-.452).
I did increase the belling and it helped with some of them but not all. Should I seat them less, would that help with a bulge, or is it possible I'm not resizing them far enough in the first stage? I have the sizer die touching the shell plate as per the Dillon instructions.
Thanks, Terry
