OK, i'm thinking of building a long range rifle 0-3000 yards, just for sh1ts. I am debating on the caliber to choose. I like the .300 win mag because the ammo isn't overly expensive and easy to find. Also how much money can I save on reloading it? I also looked into the 7mm Remington ultra mag, but it seems pretty pricey for ammo. Yes I can handle the .300 win mag, I shot one without a break and the recoil wasn't too bad. My ideal set up would be a savage 111 in .300 win mag with a bushnell elite 6500 4.5-30x50. Let me know what you guys think.
