[QUOTE="milanuk, post: 570430, member: 376"] Well, the gun is still off at the gunsmith's, and he's off hunting in Montana, the lucky dog :D Got the brass in today... picked 50 out and weighed 'em as they came out of the box. Scale used is a [URL="http://bulletin.accurateshooter.com/2011/09/sartorius-gd503-analytical-scale-measures-to-0005-of-grain/"]Sartorius GD-503 analytical balance[/URL], with readability to 0.005gn After that I ran them over a K&M expander mandrel as per my usual with virgin Lapua brass, as in my experience the necks are too tight plus with the new blue box stuff the necks are a little dinged up and need rounded out. Next step was to measure OAL so I now what minimum OAL to trim to. Measuring was done with a Mitutuoyo Digimatic 6" digital caliper, reads to 0.0005". Over the next few days I will be doing the trim/chamfer/deburr stuff, and checking the case wall runout and neck thickness runout - not necessarily germane to this particular test, but information I want for other reasons. Currently inputting the data into a spreadsheet on Google Docs (which should be available from this link [URL="https://docs.google.com/spreadsheet/ccc?key=0Ar-pKIld5bpCdHoxVXBVMm1RbllNdG9ZVnVsRFp0OXc"]here[/URL]) so that others can see the raw numbers and download the data for themselves. What other measurements do we want done on the virgin cases? Speak now or forever hold yer peace... :rolleyes: [/QUOTE]
