I am confused,
I'm looking at reloading data from different manuals. Same weight bullets have totally different min and max loads.
For instance with a Speer cast bullet, 45 L-SWC with Alliant Unique powder, min load 8.6 grains and max load is 9.5 grains. Muzzle velocity 891-941 fps. With a Hornandy bullet 45200 HP-XTP min is 6.2 and max is 7.1. Velocity 600-800 fps. Also with the Unique powder. Both bullets are 250 grains.
How can the min/max loads be so different?
Thanks for any info!
