Only a small handful of other cartridges have served dual roles as well as Remington's Big Seven. It has established an enviable record as a big game cartridge and as an accuracy cartridge for 1000 yard competition. Sierra, Hornady, and Speeroffer superbly accurate match grade bullets in 7mm caliber, and those firms as well as Nosler and Remington make excellent big game bullets for the handloader. When loaded with a 140 grain spitzer, the 7mm Remington Magnum is a powerful and flat shooting cartridge, but for all use on game up to the size of elk and moose the cartridge is seen at its best with a 160 grain bullet loaded to about 3000 fps. For big game loads, the single best powder for use with all bullets weights is H4831. When loading the heavier bullets, H1000also does a fine job. In target rifles, faster burning powders such as H4350 and IMR-4350often produce the best accuracy with match grade bullets.
