243 or 308?

I am going to buy a Mossberg 100atr from bass pro, but I can't decide if I want a 243 or 308 for decently long range shooting, probably max of 600-800 yards. I don't hand load and don't like to spend a lot on high end ammo, but I just want to know which round is best for shooting at least 2" groups beyond 100yards for a budget shooter.

Definitely 308. It's an inherently accurate cartridge with (like everyone says) many many more "off the shelf" options as far as ammo. Hornady makes a 168gr BTHP load that shoots sub moa out of the box from my Tikka T3 and for hunting the Winchester Silver tips 168gr (Molly coated BT) shoot almost as accurately but awesome on deer! Not sure where you are at but, if in the land of bigger deer that bullet knocks the bigger deer down in their tracks. I have several deer run a long ways on 1,2, even rounds through the lungs but, have never had one go more than 20 yards with 1 rounds in the lungs on the 168 Silver tips from my 308 and usually drop in their tracks! At the same those 168HPBT have served me well out to 600.Have been able to stay within a 6" painted circle at 6

Don't want to take way from the 243 because they are great - Good ballistics very flat shooter (Flatter than the 308) but, I quit using them on deer unless maybe the deer in your area are pretty small.
