This is old stuff.
I've got to go with a 148 gr. HBWC. You can pick the powder. I've shot a ton of Unique but there are so many new, cleaner powders out there, you be the judge.
Another good thing about the HBWC is you can turn them around and make an awesome home defense load. They won't penetrate a wall like JHP or a solid LC bullet, but they will expand to 50 cal at 700 fps.
