I've used most brands mentioned. I have had excellent results with LC and RP in my 30/06. I have used Winchester in my .243, but have since switched to Hornady. I use Hornady in my 300 win. mag as well as Nickel plated Win. I don't think there is a perfect brass. Everyone has different results and preferences. Use what you have access to and buy something different if you choose and decide for yourself. CJ
