I have used several brands, both LRP and SRP, with good success. I recently retired a batch of 50 Norma brass that all had 15 firings on them with a fairly stout charge. They could have gone a few more loadings, but I could see the shiny ring starting to show above the web. Even the "cheap" brands will shoot well in Creedmoor if you sort them by weight, although primer pocket life will be shorter. My vote for "best bang for the buck" brass in Creedmoor would be Starline.
