I'm going to have a T/C Encore Pro Hunter built up for an all purpose long range hunting rifle. First off, I know there are accuracy issues associated with these rifles but I'm hoping with a hangar bar and professional trigger job I can have good, reliable accuracy. I'm on the fence in regards to the caliber. The two I'm looking at are the 6.5 Creedmoor and the .260 Remington. I'm not a handloader, so I will be purchasing factory new ammunition. The two calibers seem to be pretty close in terms of ballistics. Are there significant advantages of one over the other? Thanks for your help.
