How far can a 300 savage shoot?

I have a fine remington model 721 in 300 savage caliber,and I handload the speer 150gr grand slam bullet in it.I have never been afraid to shoot out to 200yards with it on deer size game.This fine cartridge has been killing deer and black bear since 1926,and doing a fine job! I believe that if more people discover this fine old cartridge it would be in more use today than ever.Enjoy yours because I would never sell mine.
