Picked up a box of the Speer 70gr #1053 to try with Alliant 2000mr powder.
I've had excellent results with this powder in other heavy bullet for caliber applications, where I see little pressure signs, strong velocity, consistent speed, and great accuracy.
Alliant lists this particular bullet in their suggested data for the caliber and powder.

First impression is good so far. I'll get it over the chronograph later in the week.
