Yes it is! But have to wonder what pressures really are at that speed. Looking at the QL FOTIS just did makes me wonder even more.
But just went to Alliant site and they state with 105gr Amax 3078fps in 24" tube at 46.7gr so guessing RL26 is REALLY making good use of the longer barrel, interesting for sure.

Is rl23 in the new update? I wonder how it compares. Or maybe even that new imr powder- 7977?? Isn't it supposed to be double based? Might produce so pretty good velocities on certain applications as well...

ReLoder 23 is in the update (as is ReLoder 26). However, the new Enduron powders from IMR are not included in this update. I notice a number of European powders that I haven't seen before. As I work through the list, I am looking for matches between the two new Alliant powders and some of these European powders, as was true with ReLoder 17 and Elcho 17.

Sounds good!..I like the big bores as you know pal, but I'm kind of hooked on my Tikka .243, it's great to shoot, and great for medium skinned game. I have a black bear hunt booked for September, taking both the .375 and .243 with 100gr PT's, might just use the .243 pal
