Now, that's where I'd suggest a different path...
I had a bunch of 6-1/2s I used up first, saving the 7-1/2s for later, not knowing their characteristics. If I had, I could have used some of the harder primers sooner and kept the softer ones for guns that needed them. Another thing that bit me was the bricks of Fiocchi LRPs I had kept in reserve and when I finally broke those out I found the anvils protruded just enough to give trouble feeding through my progressive press. Also the 8# can of 4895 that turned out to have been damaged and rusted inside. All that is to say I recommend using a small portion of anything you think you have in stock to make sure it works well for your purpose rather than saving the unknown materials for last.
Just my experience.
