Monashee,
N-165 works pretty well in my rifle. There have been several guys post loads using that powder that have been real good especially with 140's. Looking at the powder rate burn chart I cannot help but think that RE22 would be as good but I haven't tried it.
Hopefully I can get out to try the 120's this week. As soon as I do the results will be here. If my NULA likes them and performs like HillBillyBears rifle she'll go Pronghorn hunting this fall with H4350 shoving 120TTSX's.
