I'm thinking you will like that 358477. I've been using one for several years and it is still my favorite general purpose bullet for 38 and 357. I use 1 to 16 tin to lead usually. This is hard enough for the moderate loads I use. Your wheel weight metal will work fine as is for light to moderate loads, but a small amount of tin may make it pour a little easier. Hopefully, your sizing die will be 358 or 359, that usually works out well.
It sounds like you are off and running, best of luck. Ken
