I just picked up a set of 6.5x57 RCBS dies and am toying with the idea of one but 2 of my favorite rounds are the 6.5x55 and the 7x57 mauser and somthing tells me when you have these 2 rifles well whats the point as it would just be another batch of brass and ammo to keep track of,oh well I guess we will flip a coin......
