I am working on 7mm Mag and bought some 150 TTSX and cant find any load info for RL26. I wanted to see if any one had load data for it. I called Alliant and they were not much help. they gave me the same 140 data on the Alliant powder site and said I could reduce it a little. I was hoping for a little more precise starting point.

I have RL22 and RL26 I have been using with 160 Accubonds with the best results coming from the RL26.

Thanks

I havent tried RL-26 on my Accubond LR 150’s
I have only used IMR 4350 & RL-22

RL22 charges are from 66.0 to 68.0
The load I settled on 67.6 flying at 3250 fps avg with single digit SD’s out if a Savage 116 25” barrel about 20 thou jump.

IMR4350
Started at 60.3 to 62.7
Settled on 61.7 at 3100 fps
The SD’s were high teens but the 1.8” groups I get at 300 yards has me loving it.
