Load cheapo plated bullets like lead. And to the low end of the scale, it doesn't take much to peel the plating off. Do not crimp them but just enough to see, too much crimp will cut through the plating.
Do not try for full power magnum loads with Win 231, it is a target load powder and will peak to high pressures if you push it too far.
With that combination I would not go beyond the starting load.
If that is one of Lee's oddballs where the starting and maximum loads are the same, deduct at least 10%, better 15%.
