I'm looking to load 200 LSW for plinking in my .45 ACP, but the manuals I have are very contradictory.
Using Unique, Alliant's guide says 5.1 grains max load for 810 fps @ 9600 psi.
Lyman's manual says 7.5 grains of Unique for a max load with 913 fps @17,400 cup and a starting charge of 6.0 grains for 717 fps @ 11,400 cup.
Being new to reloading, I loaded 5 rounds with 4.9 grains of Unique with an oal of 1.235, which I figured would be a safe starting load, going by Alliant's numbers. When I shot them, they shot extremely low, 4 inches at 10 yards. I don't have a chronograph, so I can't say for sure, but I would think they are very slow.
Is a lower POI consistent with 200 LSWs, or is my load to light? I have been loading 230 FMJs with good results, but want to switch to lead for the cost savings.
Thanks.
