Norma brass is probably the best brass out there. I mean there may be better or comparable stuff out there but it is not Winchester,Remington,Federal or Hornady lets just get that out of the way right now. Any company that goes thru the trouble of CNC machining a primer pocket makes an excellent product. The brass lasts much longer than comparable US brass and is dimensioned correctly and not sloppy one bit like most US brass is. Their loaded ammunition is expensive but so is any US manufacturers loaded premium ammo just look at the prices at the local gun store and then tell me. I have used Norma brass for my 280 as well as that from Remington and there is no comparism the only problem I see is that the Norma is 2x the price but worth every penny.
