I currently have both a 7 SS and a 300 Sherman mag. The brass is expensive or takes some time to prep from parent cartridges but they are well thought out cartridges. The 7 SS I had built to shoot the 175 and 195 Berger Elites, the 300 Sherman will be used with 215 berger hybrid and hopefully the 245 EOL if it ever comes to market. The next new cartridge I'm looking at is the 6.5 SST, It looks great for the new 150 smks
