Ok, I have had great success with a several jar sizes....I wanted to try a 16oz size. I have the 16oz straight sided from Fillmore, it is 3" in diam.....I use 4633 and tried the 60-44-18. It had great throw, no hang up but an UGLY black jar when it was done. Then I used the WSP low smoke zinc19. It left no hang up, the jar was so clean when done, but the throw wasn't great...which one next? I can't stand looking at the black jar, but the throw was good...............suggestions please.......
