Im running 50.5 grains BG with 120 TTSX and have gone as high as 52.0 without issue. I have not used 120 BTs yet with BG powder.
I had great luck with Varget and 120 BT. Im using a custom action as well. This load is safe only in my rifle! Any use of this info is at your own risk! You need to reduce and work up as usual!
