I don't know about Dashers, but recently bought some Peterson brass for my second 6BR. It's substantially heavier (thicker) than Lapua brass. I don't remember checking overall length on it. Seems quite well made though (at this point I've only got 3 firings on the 200 pieces in use.)From the other posts I take it most 6 dashers are chambered off the Lapua standard. The gunsmith I plan on using also mentioned liking Peterson brass.
