Friends,
I refer often to the 1967 Lymans #44 in my reloading. Something there puzzles me, though. In loads for .38 Special, using Unique powder, as you go from heavy bullets to light, there is a sudden jump in the amount of Unique listed as max. For 150 grain bullets, the max is 5.5 grains, which is what you would expect. Then for 141 grain it is 6.8 grains; then for 121 grains it is 6.9 grains. That's alot of Unique for .38 Special. And that 6.8 grain charge is under the 358495 wadcutter! The velocity they list is 1295 fps. I don't doubt that 6.8 grains Unique under that wadcutter would produce 1295 in a 6" barrel, but wouldn't the pressure be through the roof? Why the sudden jump from 5.5 grains to 6.8 grains, and is it safe like that?
Thanks, LBS
