As already said, he loaded it to Bullseye specs and it is down on velocity. Bullseye is one of the fastest powders there is. So while he may have took a chance to start with, I see no problem with using it up.
This comes up all the time. The term "handloader" is somewhat of a misnomer these days. You can buy some equipment, buy materials, buy a book and do step for step what the book says. Yep, you are handloading some ammo........but that does NOT make you what the real definition of a "handloader" is.
Now I have no idea of the skill level of the OP, but he has already established a baseline of sorts. So throw it out, or use it up, either one
