What kind of Vanguard is it? Sporter? Deluxe? Synthetic?
The .223 Rem. is a pretty specialized cartridge. Cheap to shoot, but not really good for hunting medium game. I know that's debatable. But we're all grown up here, so we can admit that there are better choices for deer sized game.
I wouldn't mind having the .223 in a Weatherby. Well made rifles.
