I've always used Remington brass and it has worked well for me. However as of late it's getting very hard to find. I was running low on 25.06 rem brass and resized rem 30.06 brass and that's what i'm currently using. I also use rem brass in my daughters .260 but recently picked up some Lapua for a great price from a guy who sold his .260. When I run out of rem brass i'll give the lapua a try in her rifle.
I've never used Winchester brass but I have several friends who do and love it. It's my understanding that Black Hills uses Winchester brass in their factory ammo so it must be good brass because they produce some darn good stuff.
