My old marlin 336 likes 36.0 grains of leverevolution. Put first 3 into half inch at 100 yards. Fourth shot opened it up to just under an inch and was getting 2300fps on my chronograph. I set up water jugs at 100 yards to see how well they expanded and did pretty good. Brobee has an elk hunting video on YouTube and he tests different 30-30 bullets, including the tsx, that’s worth watching
I've actually obtained over 2300 FPS with my 1941 Winchester 94 with a 170 grain bullet using 37 grains of LeveRevolution, with no excessive pressure signs.
From what I understand, Barnes bullets need to be flying fast to open up properly, if you are only expecting those velocities with a 150 grain bullet, I'd look for another load.
p.s. I checked the data for the 150 TSX and it maxes out at 28 grs, 2,020 fps. The all-copper bullet must raise pressures significantly.
According to their online data published on their website, the max is 36gr LVR for 2300 FPS from a 24" barrel. The second fastest is 2187 or so, and they descend from there.
