In another thread the topic of QL and is it worth the money was raised. To me it was worth every penny.
Here is an example of how I like to use the software. This is a generic load. For accurate data you need to measure your brass and bullets including actual case capacity in gr of water.
This shows what is predicted when powder charge is varied over a range. This is useful because it lets you have an idea of a good start point for a load.
Cartridge : .30-30 Win. (SAAMI)
Bullet : ?? .311,166,N.O.E. Bullet SC311-165-RF GC AH4
Useable Case Capaci: 37.300 grain H2O = 2.422 cm³
Cartridge O.A.L. L6: 2.550 inch = 64.77 mm
Barrel Length : 20.0 inch = 508.0 mm
Powder : Alliant 2400
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
