The 270 Weatherby Magnum is an excellent, accurate, and flat shooting cartridge that is capable of taking any big game in the lower 48 states and is one of the more powerful 27 caliber cartridges, when loaded with 130 grain bullets at 3300 feet per second it is a very adequate round for deer at 500 yards and when loaded with 150 grain bullets at 3200 feet per second it is a very adequate round for elk at 400 yards.

 The 270 Weatherby Magnum will recoil considerably with 150 grain bullets but if loaded down with 110 grain varmint bullets to a velocity of around 3,400 feet per second the recoil is quite tolerable.
