Was shopping for some bullets at midwayusa.com
http://www.midwayusa.com/viewProduct...tnumber=915881 and this caught my eye: "Awesome bullet for the 300 Whisper. This bullet will cycle flawlessly (shooting subsonic loads) when RL7 is used. When seated to 2.200this bullet aligns perfectly in all magazines (bullet ogive contacts front magazine indention correctly, thus preventing magazine bulges, etc...). Under 1MOA is a common occurrence when loaded subsonic. This bullet simply cannot be beat, especially when comparing prices with other heavy weight match bullets." I have never seen load data for RL7 is this the same as Alliant Reloader 7? I know this powder is used for the .221 fireball, don't know where this falls in the burn chart. Anyone else out there use this bullet/powder combo or powder for other bullets?
