[QUOTE="woodcr24, post: 1211530, member: 84411"] I don't have QL at present; it's on my list of "necessities" for purchase over the next month or so, so can't run the numbers for you at present. Loads that I have seen published online for the .260 Rem AI tend to reflect the use of a longer barrel than you are considering; generally, it seems that 26" is the shortest with data published. It's possible that there's a reason for this, meaning that either someone has determined that the gains are noticeable only in barrels that are ≥26", or that people running the AI cartridge in shorter barrels haven't been as vocal (or, I simply haven't found it). Something to consider is that you might very well be using different projectiles for hunting and target shooting. Consider what your desired energy is at the POI and whether the projectile that you plan to use will deliver that energy at the range that you are looking to achieve, as well as whether or not the remaining velocity at that range permits adequate expansion. In the .264 category, the 120-grain TTSX is a very capable projectile for all of the game that you mentioned, but the optimal velocity for terminal performance seems to be >1,800 fps. You ought to be able to send that from a standard .260 at close to 3K fps from the 23" barrel. It might be enough for your requirements without the AI. [/QUOTE]
