Hi Softpoint. There is no ammo that is perfact for your gun right off the shelf! Factory ammo is just good all around ammo made for those who don't reload, it's not the perfact ammo for "your gun". You can take two brand new guns and one of them may come close to liking the factory ammo better then the other, but thats about it. You should think about doing some reloading, this will help you in getting and staying under 4'' groups. I own 3 308's and it's a good round, but none of them or anyother gun i own shoot great with factory loaded ammo. I dorped a deer at 165 yards with an old Enfield #1 mark 3-2A1, bone stock gun sitting in Ram-Line stocks without a scope! But the gun had the right ammo "made for it" in it. I could care less how much money you spent on your gun, the scope or your SUV to get you to the hunt! It's all in shot placement and that takes the right ammo setup for your gun. Now if you are going to use factory made ammo, the your going to have to play around with it. You should be able to get down to 2" groups with the factory loads. Now something you do need to remember about ammo for the 308's is this (here we go on this one again! I know-I know, iam going to hear about this!) Softpoint, don't shoot military surplus ammo in that gun! The gun was made for "308 Winchester ammo" and not for 7.62 x 51 military ammo! There not the same ammo, don't be fooled into thinking that there the same, there not! My Enfield #1 mark 3-2A1 is 7.62 x 51, my Howa model 1500 is a 308. Now my Kimber M96 is stated as a 308 Winchester, but!!!!!! It's a small chambered 308. Each of these guns has there own set of reloading die's. About the only real way to find a good factory load for your gun is to go out and buy yourself 3 to 5 boxs of factory ammo and start playing! This is something that is best done "without" all of your buddys sitting around making jokes and cutting up. Just remember, most any factory made rifle with the right factory made load, will or should be able do 2'' groups at 100 yards. Well, so long as you have the sights or the scope dailed in! If you havn't had the scope line bore sighted, you should if your useing a scope? Now with open sights, a 4'' group isn't bad for a start with factory ammo, it isn't perfact! But it could get you a deer? I've been hunting with a 308 for over 20 years now, it's a great all around round. She will drop most anything you point her at with the right ammo in her, here in the states! Paw
