There are several different calibers that can be called "7mm". They are not interchangable. If you have any doubts about the right cartridge for your gun, take it to a gun store so they can show you the right ammo. Using the wrong ammo can KILL you. Please be safe. Now that the obligatory safety warning is out of the way, let's talk about some of the cartridges. Remington, Winchester and Weatherby all have 7mm magnums. Remington also has a non magnum 7 mm, also known as the .280 Remington. There are many others, including the 7X57 (also known as the 7mm Mauser), 7X30 Waters, 7 TCU and my personal favorite, the 7mm-08 Remington. Hope this helps!
Basically the case is all. Same caliber bullet, but the case is shorter in the ultra mag. Its basically just a smaller round, bigger punch.
It should be marked on the barrel. There are other 7mm rounds besides the 7mm Mag.
30/06 is one
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 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.
The 7mm mag has mare pressure that a 270 win.
no!!!!!!!
Out to 1000m or so
284
that would depend on which 7mm cartridge you are referring too. ie 7mm-08, 7mm Rem mag, etc
