I'm trying to reload some low pressure 38 Long Colt to keep under <12,000 PSI for and original 1892 revolver.
I was using 3.8-4.0 gr of unique with a 125 gr .358" bullet, in order to use a slower powder to keep pressures low. Quickload tells me 3.8gr should give around 10,000 PSI, and 4.0 gr gets around 11,000 PSI (maximum)
As it turns out, even with 4.0 gr of Unique I'm getting >100 fps ES, which I discovered to be because of position sensitvity.
If the barrel is tipped down before each shot, I get velocities around 570-625 fps.
If the barrel is tipped up before each shot, I get velocities around 800-900 fps.
Any tips on a powder that is LESS position sensitive than Unique?
I'm thinking of going something faster like bullseye or red dot, and aiming for around ~750-800 fps
