I received my copy of quickload yesterday, so I am very new to the program.
I entered in everything for my 250 grain missouri bullets cowboy #1 45 colt load using 7.1 grains of Unique.
Quickload estimates a velocity of 842fps out of my 5.5" barrel. My shooting chrony shows a mean of 655 for 5 shots. Lowest was 622, highest was 686. My Dillon powder measure was throwing anywhere from 7.1 to 7.3 grains which would account for the spread in velocity.
Any idea what might be causing this?
