It uses default parameters, and may not be very accurate for your gun without some additional information and tuning, so use it with proper discretion.

I see that it differs from the calculation provided by "mrawesome22" using the same program. A quick look at his output screen in the previous post showes that he used an over-all cartridge length of 1.100", while I used the default (maximum) COL of 1.135". YOu can see the lower pressure and velocity for the 5.5 grain load in my output table.

So, pay attention to YOUR COL and remember that this is just a computer SIMULATION, not actual pressure-tested load data.

Cartridge : .40 S&W (SAAMI)
Bullet : .400, 150, Nosler JHP 44860
Useable Case Capaci: 12.216 grain H2O = 0.793 cm³
Cartridge O.A.L. L6: 1.135 inch = 28.83 mm
Barrel Length : 4.0 inch = 101.6 mm
Powder : Alliant UNIQUE

Predicted data by increasing and decreasing the given charge,
incremented in steps of 3.077% of nominal charge.
