Thank you, RiverRider, for doing that. Now, I don't have any experience interpreting Quickload calculations, so please check my interpretations:
1. Any of the four powders I asked about appear prudent choices for this pressure limitation and my bullet choice.
2. 2520 appears to be the most likely to produce the highest velocity within the pressure limitation.
3. Any of the four might produce the best accuracy, but since H322 produces the lowest muzzle pressure it has the better chance to be the most accurate.
4. Should I consider the calculated charge weights for each powder as "Do not exceed" charges?
By the way, I didn't state it but my velocity goal was 2250fps, and I'm happy to see that it looks attainable.
