Mine is a Krieger #10 which is .940 at muzzle and specifically for the 1,000 yard light gun class. Many people still use the Winchester
brass but the latest stuff from Norma is very good and what I shoot. If you get the Norma, make sure you get it from lot #4, this is very good brass but the older stuff is not. The best way to tell if it is from lot#4 is to weigh it, if it is around 202-205 grains, it is the good stuff. If it's up around 220, it's from the previous lots and you may as well throw it away. The winchester works but you have to sort through it more. I don't know anything about the Lapua or Hornady.
