Stay frosty, my friend.
Having shot the 6.5-06 a lot I would recommend 260 Rem with Lapua brass. What ever you shoot go with Lapua brass. I love the 6.5X47L case, I'm going to build the 6mm-6.5X47L but not for 1000 yds. I feel the 6.5X47L is too small for good 1000 yd shooting. The 6.5 Creedmore uses Hornady brass. You do not hear good things about Hornady brass.
The 6.5X47 currently holds 3 IBS 1000 Yd. records. 260 holds 1 1000 Yd. GBA record. Lapua brass on both.
