[QUOTE="Mikecr, post: 1229625, member: 1521"] 22" barrel is too short for either cartridge. You'll have very high muzzle pressures, as a good bit of the powder will not be burned until releasing at the muzzle(big fireball). The 6.5x55 is by far the better capacity for 140gr bullets. While the plain 260 is under capacity for 140s and slightly over capacity for 130s. IMO, accuracy is the most powerful of all ballistic attributes. If I were set on a short 26cal, I'd go 6.5x47L, 130gr bullets, and ~24" barrel. It's faster powder and more accuracy in a short barrel. [/QUOTE]
