Want to learn the basics of long range shooting. I'm not a hunter, (although my daughter and son in law are AND both want to learn more long range basics), I don't plan on spending a ton of money, (modifying the gun is part of the plan and desire), looking at 700 Remington, Ruger American Predator, etc. My first though on caliber in .308, it's a well established round, relatively inexpensive and AVAILABLE! Not much luck locating a gun to buy right now, (duhhh, it's hunting season!), a local pawn shop has a Ruger Predator in 223. Not sure if this MIGHT be a way to go if for nothing else, it will allow me to find out if this something I'll want to do more of. I already load 223 so cost of ammo is the cheapest way to go. From want I've learned, 223 will work out to approx 600 yards. I've read of people shooting farther with 223, but sounds like more effort than I'd be able to coax out of an inexpensive gun. Should I wait on a .308, no big rush to get a gun...but y'all know how that is! Thoughts?
