Page 973 of Speer #14 has the following data:
.45 TMJ RN
230 grain
COAL 1.260"
H. Universal: Start charge: 5.5 (730 fps), max charge: 6.3 (841 fps)
231: Start charge 5.6 (789 fps), max charge: 6.2 (858 fps)
But Hogdon's website lists:
230 GR. HDY FMJ FP
COAL 1.200"
Universal: Start charge: 5.1 (716 fps), max charge: 5.6 (844 fps)
HP-38: Start charge: 4.3 (699 fps), max charge: 5.3 (834 fps)
I always like to cross-check loading data. Winchester's loading center website redirects to Hogdon's. There's no overlap between Speer's start and Hogdon's max for 231/HP-38, and there is only .1 gr difference between the max and minimum for Universal. I'm scratching my head.
Note that COAL: 0.060" is the difference between a flat point (Remington factory round) and a round nose, so that should account for the 0.060" difference rather than how deeply the bullet is in the case.
Can someone please cross-check these powders against one of their manuals?
