I tried LeverEvolution with 130 TSX's in a 24" barreled Model 64 Winchester. 38.5 grains(Hodgdon's max for 150's) gave 2660 fps with ES=10fps for three shots. I then tried 39.5 grains and things got a little erratic. Velocity jumped to 2790 fps and ES=63fps for three rounds. The lever was a little sticky opening on the fastest round of the three.
The rifle really needs to be recrowned so groups open quickly as velocities increase. I am going to recrown the rifle and try 39 grains one of these days.
That doesn't make sense. I got 2400 across my chrony out of my 336 at 35.5 with 150s
