If I were buying rounds instead of reloading I would definitely go 6.5 because the 260 factory rounds are like gold! The cheapest on gunbot is 1.55 a round and that isnt match ammo! I buy the factory stuff for 1.10 each in 6.5 and then I reload them several times. I have six reloads on the last forty so far (7 shots) and I have lost 2 pieces of brass due to my negligence. I emulate the factory round for my reloads and all is good. Thats all I need!
