For my favorite sport, long range deer, antelope , and coyote hunting
, the most accurate cartridge I have used out to 1000 yards would have to be the 6.5x284. The rifle that impresses me most is an original Remington 1903 A3 made in 1944. i have owned it for many years, bone stock with original trigger and a peep sight, Shoots a little over an inch at 200 yards, 5 shots, with a Hornady Spire Point 150 gr bullet and 52 gr.of IMR 4350. I have a warm spot for this rifle and it would definitely be the last to go. Makes me sometimes wonder about all the time and money I have spent on playing with bedding, barrels, triggers, etc.
