I've had a bit of time with the 70gr Speer bullet.

I'm currently into a Varget load that is showing good promise.
I shot a group yesterday in the wind that printed a horizontal line of impacts, less than .100 vertical dispersion.

Tonight at dusk I sent one of those on to a 1" target marker, printing dead on vertically, less than 1/4" off the center of the marker.
Good cold barrel zero. This load has the brass growing about .001" after going through the sizing die.

More to follow, but very good so far.
