I use both reloader 23 and 26 in my 6.5 x 2 84 Norma both have good velocities but I do get a higher velocity with 26 and better case fill although 23 is more accurateI'd like go see the 23 and the 26 in a side by side test. I don't have either but may have to get some. My buddy stepped up to RL26 in his .243. Woo Hoo, speed and accuracy with a 105 bullet.
