Tried RL26 with the Hornady 105gr HPBT Match, loaded up to 49.5grs of RL26, accuracy was good if not alittle better than RL19, but we're talking groups in the 2's so no use worrying about accuracy and go for the horse power since the groups were the same. Couldn't get the velocity that I do with RL19, with RL26 I got 3252fps and with RL19 I got 3387fps. This was out of a 26" Shilen Select Match barrel.
