Go here to Noslers direct site and get the blem 300 win mag brass for $22/50----that's a good deal.
Then go back to the home page and get some blem ballistic tips...partitions....accubonds to round out the order and save some big $$$$. Also check out other calibers.
I buy alot of stuff here and have had really good luck and think it's an excellent value.
Or if you want another good deal go to natchez.com...they sell federal primed 300 win mag brass for about $17/50. I've used it and it lasts as long as win/rem for me. Probably not in the class of Lapua but no where near the price either.
