Thread: Which 6.5

If trying to decide between 6.5x55, 6.5 Creedmoor and .260 I would just look for what calibers are available in the rifle you want.
Tikka and Sako seem to be sticking with .260 whereas Ruger and Savage have jumped on the Creedmoor band wagon.
6.5x55 will come in a medium/ long action whereas the other two are short action, but if you get a Tikka or go custom you may just go long action anyway.

6.5x55 has the best selection of factory ammo, but it's not loaded very hot. Reloading for the 6.5x55 should get you the highest velocity.
6.5x55 and .260 both have Lapua brass along with many other brands, Creedmoor has Hornady and Norma but not Lapua.

I've got a .260 and am happy with it, I would consider 6.5x55 for my next purchase though, no reason other than a tiny bit faster.
6.5 Creedmoor has jumped to stardom pretty quickly for good reason, but the main selling point is the availability of good well priced match ammo in the states, which isn't major factor here in NZ. 6.5-284 is certainly the best balistically, but burns barrels a lot quicker and doesn't come in a huge amount of factory rifles.

A Sako or Tikka in .260 would be a good lightweight rifle.
