Hi Mike, there is no expander button on the bushing die. It is the bushing alone that sizes- without pushing the case back and forth.

Thanks Paul for helping out with this thread, all good advice that needs to be followed. It really does make such a big difference.

Retumbo / 2225 or H1000 / 2217 will be ideal. Start load 100 grains with either. Make sure you use a chrony and start looking for sweet spots at 3050fps up, though you may also want to take note of low nodes.
