My fav cartridge is the .260A.I. However, you stated you want minimal brass prep. To me that would include NO fireforming. With that said, either a 6.5 x 47 Lapua or the 6.5 Creedmoor is about as good as it gets for 600 yards. Even with "blustery" wind conditions, a good score should be forthcoming. Both are easy to tune, very, very accurate and almost no recoil..

As close to plug and play as can be had.
Lots of 600 yard matches won and plenty of “cleans” shot with a BR.
Except, don’t hesitate to shoot those 108’s jammed.

Technically, wouldn't that need to be necked down to a 33-70 to stay within the rules?45-70 or whatever you have on hand. Go shoot, see if you like it.
