Had another quick range day to confirm the 120 gr NBT load and try a new 139 gr Scenar load. I have to say, this little rifle is a shooter, better than me.
As you can see, the load that went 0.69, went 0.81 with the nut behind the butt.
I fired 3 -120 NBT on the L hand dot first, 2 to 400 on steel, waited 5 min then back to 100 for 5 of each 139 gr scenar load 5 min in between, then to 400 with 3 more. I realized I had one more 120 gr NBT load and fired it at the same target and for a gun that had just fired 18 rounds with little cooling and was very hot, it placed it right back near the original group. Also, the vertical between both loads is very close for two bullet weights almost 20 gr apart from each other. Excellent performance in my book for a light #1 barrel in a lightweight rifle. There is a technique to shooting these ultralights and they show flaws real quickly in a shooters form, humbled me for sure. but then again just my .02.
