It should be marked on the barrel. There are other 7mm rounds besides the 7mm Mag.
Depends on what game you are hunting and how good a marksman you are.
One is longer, one is shorter.
Depends which 7mm your talking about. The only 7mm I know of that has a larger case capacity than the 300 wby mag is the 7mm Remington ultra mag or 7mm rum
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!!!!
The value of a Harrington and Richardson 7mm Remington mag serial number 52897 depends on its condition. This gun in excellent condition is valued between 125.00 and 200.00 as of 2014.
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.

100-400 or so.
NO!!! 7mm-08 ammo like ALL ammo should only be used in guns specifically marked for that type of ammo. it is unsafe to use any ammo whose markings don't match the gun you are using. even a small difference like +p or mag can cause serious injury or death<, even if the ammo looks like it is the same or "fits"in the gun. if unsure of any ammo/gun please take to a local gun shop for professional opinion
no!!!!!!!
