Hey guys, looking at purchasing a new long range rifle & love the looks of the Lithgow Woomera which comes in 6.5 or .308. I had my mind made up on getting one in 6.5 Creedmoor until I realised how savage it is on barrel life compared to .308. The range I use is only 550 yards long & from what I can gather both calibers are very similar out to around 500-600 yards however I would be roughly doubling the life of the barrel if I chose the .308 . Is is there any reason going with the .308 would be a bad move for my intended purpose? Thanks.
