I am about to start testing the 25 Creed. I have done a little research and can buy brass form Peterson and Alpha. This is where all opinions are welcome. Peterson bulk runs about 91 cents a case. Alpha runs about 1.15 a case. I think I may better served necking up Lapua 6 creed or necking down 6.5 Creed brass. I have never in the past done either of these. Any help or advice would be greatly appreciated. The Lapua brass run about a buck a case and is readily available. Would it be worth the extra time?
