7mm Remington Magnum History and General Information:
The 7mm Remington Magnum was developed by remington and introduced to the public in 1962. The 7mm Rem. Mag. has enough power, using 140 grain bullets it will drop deer at 500 yards. Using 160 grain bullets it will take elk at 500 yards as well. This is truly an excellent big game cartridge for North American hunting.
The 7mm Rem. Mag. offers one of the best compromises of power, recoil and bullet selections of all high power class of rifles. For big game hunting in North America it is highly rated as their is nothing walking in the woods that this 7mm Magnum can't handle quickly with proper bullet weight, loading and shot placement. Its no wonder this cartridge in five decades has become so popular world-wide and especially in North America.
The 7mm Rem. Mag. has been chambered by most major high power rifle manufacturers for quite some time and they have offered these rifles with rifling twist rates from 1 in 9" - 1 in 10". If you handload for this cartridge,
the 1 in 9 1/2" twist rate will give excellent bullet performance from the 139 grain offering by hornady to the 160 grain boattail of speer and it will shoot the remington 150 grain core-lokt bullets with incredible accuracy.
The 7mm Rem. Mag. when loaded with 139 grain bullets recoil is quite minimal and controllable when loaded with 160 grain bullets the recoil increases quite a bit, a good recoil pad fitted to the rifle will tame the recoil before it gets to your shoulder.
I have owned more than a few 7mm Rem. Mag. rifles over the years, the first was a Winchester model 70 with 24", 1 in 9 1/2" twist barrel purchased in 1974, out of the box performance was 1 hole groups at 200 yards shooting factory remington 150 grain core-lokt bullets.
Performance was well above board for that 7mm Rem. Mag. rifle, several years later, after several thousand rounds, throat erosion was affecting its accuracy and I began experimenting with bullet and powder combinations to regain its accuracy. Using 160 grain speer flat based bullets, slightly lengthening the cartridge overall length, backed with a charge of IMR 4831 powder and ignited with a remington 9 1/2 large rifle primer (Not Magnum), superb accuracy returned.
(Accuracy: 1 hole, 5 shot groups at 200 yards).
Note: The above 7mm Rem. Mag. load is extremely effective on elk, moose and bear and definately not recommended for deer hunting as the destruction on a deer shot with that loading is to high if shoulder shot.

7mm Remington Magnum Barrel Specifications:
Because of the velocity range, quirky nature of .284 diameter bullets in that velocity range and the 7mm Rem. Mag. barrel concerning bullet performance with various twist rates by various rifle manufacturers, here is a barrel and bullet guide:
 1 in 9" Twist Rate: 160 - 175 grain bullets, barrel length 26" for maximum performance on large game such as moose and big bears.

The Bolt Action is the most popular rifle action type used in North America chambered in the 7mm Rem Mag cartridge, of which the Remington Model 700, Ruger M77 and Winchester Model 70 brands and models are by far the most popular bought and sold rifles.
Important Note: Winchester Model 70 rifle accuracy is guaranteed by the manufacturer to group shots at 100 yards at or under 1 inch.

7mm Remington Magnum Rifle Accuracy:
 Most 7mm Rem. Mag. rifles are more than capable of excellent accuracy when set up properly and shot from a benchrest. Usually the trigger on most factory produced rifles will need some adjustment to aid in rifle accuracy, of these the Winchester Model 70's are the easiest to adjust. To achieve maximum accuracy from your 7mm Rem. Mag. Autoloading or Bolt Action rifle there are several other things you need to do that will increase your rifles overall accuracy capabilities.
1. Properly mount your rifle scope.
2. Properly break-in your rifle barrel.
3. Properly sight-in your rifle.
4. Use this free target designed for accurate sight-ins, follow the instructions.
Note: If you follow all of the directions in the above guides that I have written, you will achieve the maximum accuracy that your 7mm Rem. Mag. rifle pocesses. If you encounter a rifle that just doesn't group well despite your best efforts, try swapping out the scope as this is the most common fault of rifle accuracy issues.
