Should try some ADG brass just as good of quality as lapua just not the price tagReloder 26 is a pretty impressive powder in the Creed. The problem now, is getting ahold of some. It is pretty unobtanium. I use nothing but Hornady brass in my Creeds and also in my .260s. I have not had a problem getting pretty speedy loads from it. I have never used Lapua brass. I am too cheap, or uh, frugal.
