Your lot is probably different,

1200-1250 with mine is on the bottom end of the usefulness of the powder. My ES was over 100. A mag primer and more powder brought that number into the 40s, but velocity is well above what you are looking for.

Ignition can be sporadic if you go too low. I stuck a bullet in my .500 Linebaugh 27.0 gr and a 450gr bullet. Velocity was about 1075 but one shot left the bullet in the forcing cone with a glob of charred powder behind it.

I like it in the smaller calibers like .327, .30 Carbine .357 it works great.
