Is 9 grains of Unique pushing a Lee TL 452-230 TC a safe load to shoot in Uberti 1866 and 1873 Levers? The boolit weighs 238 grains after lube. What pressure and velocity am I looking at with this load. Accuracy wasn't great with 8 grains so I figured I may need to speed it up a bit.
Thanks in Advance,
