I'm looking to purchase a new Semi-long range rifle. Out to 500-700 yards on paper. I mainly want to know of a good cal to start looking at, as i really like the Remington 700 Action (But im open to other options). I do reload so ammo cost is no problem. I started looking at the standard stuff 7mm mag, 280 rem, and 300 win. I like the 6.5 creedmoor so that might be an option. What is yalls thoughts?
