Bought my first .30 Herrett barrel in about 1976. For some years the biggest problem was finding bullets that expanded well at the 10" velocities but still shot flat. Milek used the Speer 110 RN and that expanded well, but its trajectory suffered. 125/130-grain bullets of the time were too hard. A number of us in Alaska who hunted with the cartridge used to have a loose network to exchange experiences on bullet performance.
By the mid-80s we had a lot of better choices with pistol-designed pointed bullets. My favorite became the 125 BTip, although today I prefer the 110 V-Max. At 2350 fps it is not explosive and always expands well, especially on our rather small Texas deer. For larger game the 125 BTip would perform better. I found velocities too low with 150s to insure good expansion past 100 yards.
