7mm Remington Magnum....does it all in my humblest of opinions.. will work from 5 yards to as far as you'd care to shoot at one.. the only limit would be you and the quality of your equipment.... I've dropped them out to 700 yards with no problem whatsoever.. I know of individuals who've done it much further than that... I use 140 grain nosler partitions and noting else, neverhad a bullet fail and never had to fire a second shot to killany animal. Fueled by 62 grain of H-4350 and a Remington 9 1/2 magnum primer.... also the bullets are seated with a Wilson Straight line seater... HARD cartridge to beat, for multiple distance and all types of conditions..
