I’m a bit surprised that the 175 Partition doesn’t get more love.
I used the 175 Partition a lot. Loaded over H870 mostly or R22 & H4831, they ran about 2,950 fps with my 23" barreled Dakota. One deer hunting trip I grabbed the 175 elk loads by mistake and found out how good they worked on deer and hogs too. I still have a couple of boxes of the old screw machine semi spitzers with the relief groove around, the ones Warren Page used in Old Betsy. I switched to 160s because of Bob Hagel's writing and then later switched to Barnes as the grass is greener theory rather than any short comings of the Partitions.
