Which is kinda moot since its .357 data.

The speer load really shouldn't be hard to recreate. Its pretty mild. The trick will be finding the bullets you want to use.

It might be easier to just get 158gr bullets and see how close they are to the speers. Just adjust the velocity to raise or lower to poi.
