40 S&W Load: Is mine safe?
I want to use a different bullet in a load than what my load manual "Lyman 49th" lists. The bullets I have are 150 grain Nosler JHP #44860. However, the load manual uses 150 grain Sierra JHP #8430. Will I be okay if I substitute the Nosler bullets for the Sierras, given that I use the same load data as far as COAL, powder type and amount?
Thanks! |

If you start at the starting load and work up you'll be fine.
Got a chronograph? |

To be safe, you MUST re-work the load to be sure.

I do not have a chronograph, and the powder I'm using is Unique. My manual lists an OAL of 1.100", and starting/max grains of 5.5 to 6.6 (Unique) for the Sierra bullet.. If I do use the Nosler bullets I will only use 5.5 grains of Unique.
Maybe a better question would have been, "Does anyone know of a published load using a 150 grain Nosler JHP with Unique powder?" I'm not really looking for accuracy, just a fun load that I can use to shoot cans, paper, etc. |

There is a ton of loading information for cast bullets for anything from cat sneeze loads to hot hunting (or defense-type if you choose to carry home loads for defense) loads, plus virtually any style or weight (within reason) for loading. |

I realize there are more economical loads for what I want to do, but I want to make use of what I have available to me at the moment which are the Nosler JHPs, not FMJs or cast/plated bullets. Note: I do not carry hand loads for self defense. To each, their own, but I prefer premium factory SD loads for that purpose. So, again I just want to create a SAFE plinking load with what I have on hand. Any help is greatly appreciated.

Unique is not in Nosler's #6 Manual for this bullet & cartridge.
It should be a satisfactory powder; it just wasn't one that they tested for that manual.
Someone could help you with a QuickLOAD calculation, but I don't have the time to do that right now. SL1 |

Here's a load table from QuickLOAD
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.
