While the Hornady Basic Brass works well, you might want to find some 8mm Rem. Mag. brass to use instead.

Since it's inception, the 8mm Rem. Mag. has not been too successful a round (in marketing only). Because of this, you can usually find that dealers want to get rid of the brass at low prices.

True, you won't have the correct headstamp info, but you will find that this brass loads even easier than the Hornady Basic stuff.
