My target velocity for the 300 grain Deep Curl was 1800-1900 fps. I have not shot through a chrono. yet with my load. But I believe I am achieving that velocity with 120 grains of BH. I wanted to stay above 1600 fps which is the approx. velocity of 90-100 grains of powder.
I realize 1600 fps is more than enough velocity. But I was looking fora bit more down range performance from the bullet. And those extra 200 fps help out a good bit at distances past 150. Tom.
