Hey Kevin. Welcome to the forum. Boy, you really dug around to find that old thread.
It sounds like you have a load that's working for you. There are a couple of guys here that have used the White Hots. Some were happy, some not. Hang around here long enough and you will see a lot of options. The general opinion (though not universal by any means) is that magnum loads are not necessary and not always the most accurate.
