For the record i'm not suggesting that you can get 3000fps out of a blaser mag with a 300g pill - i'm suggesting that its an irrelavent and arbitary figure (and one that you have presumably pulled out of your bum anyway till the pin hits a primer) and that figure can be exceeded or near met by other more efficient (logical?) rifle systems i.e long action or "no action".
Hope you enjoy your build and it kicks ass.
