Is my PRC slow?

Just to follow up on this post, I finally got around to running these over a chrono again. Up to 2865. Idk why, but my barrel didn’t speed up until I had over 300 rounds down it. Kinda interesting.

Take ambient temp into account when making comparisons like that. If it was exactly the same and the average grew 60fps, so be it. But if your first test was in 50° weather and the second was in 80°, it's likely just temp factor. Honestly you need to test in opposing conditions to get those numbers for a solver if you really want dialed in solutions.
