As I read this, the lead pot is heating right now. It's time to get ready for the springtime pistol matches. I need to cast a bunch of bullets today while the weather is cool.
My go-to load for .38 special is a 158 grain semiwadcutter over 4.3 grains of Unique. I see that Kraig says 4.5 grains, and I don't know why I settled on the 4.3 grain load, but it's been one of my standard loads for many, many years. I suspect that it doesn't make a bit of difference between 4.3 and 4.5, but my load gives me 780 fps from my 4" revolvers and is gives fine accuracy.
