1000 Yard Gun - .260 vs 6.5 Creedmoor
I'm new to long distance shooting, so I wanted to lean on the expertise of this forum's membership in evaluating two cartridges. I'd like to build a good gun for hunting deer or shooting targets out to 1000 yards. At the higher end, really only targets, since I'm not confident I could kill an animal at range. I think I've narrowed it down to a Savage model 12 LRP, but it comes in .260 and 6.5 Creedmoor. Lapua just announced they would be selling brass in .260, so I believe quality reloading costs would be better on that round as opposed to the 6.5 Creedmoor. I think the ballistics are almost identical, so I'm wondering if there's a reason not to do the .260 and, instead, go with the 6.5 Creedmoor?
Like I said, I'm new to this, and I was hoping some of the experienced shooters out there could point me in the right direction.
Thanks in advance.
