a 223 will last you forever, 243's more expensive ammo, shorter barrel life but a great hunting rifle. 308 plentiful ammo ,barrel last forever, recoil is manageable, excellent hunting round and the best all round cartridge of the 3
If your prime motivation is to play sniper go with a .204 Ruger. Tikka and Howa make some very nice ones. The accuracy of that round has to be seen to be believed. I have a Kreiger barrel on my match AR and it can't come close to the groups I get with my .204 sniper rifle. Cheap to shoot at about 20 bucks for 20 Hornady Vmax, just not as wide a variety of it as you have in a 223. Low muzzle blast and almost zero recoil also
