Only 7mm magnum ammo made by a reputable ammunition maker provided the rifle is in working order.
your browning bar which was made in 1990 is selling for between 400-600 dollars depending on the overall condition of your rifle.
350-650 dollars,depending on overall condition and a good bore.
1966.
DO NOT DO THIS!!!! The OAL on the 7mm Mag is 2.5 inches and the 7mm Weatherby is 2.55 inches. SInce they headspace on the belt, and due to the freebore in the Weatherby, the 7mm Mag may chamber in the Weatherby. SAAMI lists the 7mm Mag/7mm Weatherby as an unsafe combination one will probably chamber in the other. DO NOT SHOOT UNLESS YOU ARE SURE YOU HAVE THE RIGHT AMMUNITION!!!!
500 USD or so.
The 7mm Ultra Mag is a Remington cartridge. THE model 70 is a Winchester rifle. Winchester does not chamber the Model 70 For the 7mm Rem. Ultra Mag cartridge.
Browning does not make a M70 semi auto 7mm nag
