| I just picked up 2 boxes of Nosler Custom Competition 185 grain JHP bullets and also Hodgdon Titegroup powder. Does anyone have any good loads using this combo in a USP Tactical 45? |

The Hodgdon site lists:
Bullet Weight (Gr.) Manufacturer Powder Bullet Diam. C.O.L. Grs. Vel. (ft/s) Pressure Grs. Vel. (ft/s) Pressure 185 GR. HDY JSWC Hodgdon Titegroup .451" 1.195" 5.0 892 14,600 CUP 5.5 956 17,000 CUP And the bullet listed is JSWC while I have JHP. I looked at Lee Precision Modern Reloading 2nd Edition and it lists the same information under jacketed bullets. So I'm guessing that if the weight matches and it is jacketed, the load data can be used. Both of the above references lists 5.5 grains as the max, however, Hornady's 7th Edition lists 6.6 grains as the maximum load using their XTP or SWC ENC bullets of the same weight. So does bullet type matter when referring load data? |
| I've got 2... Lee and Hornady. I also cross reference with data from reputable websites like those of powder/bullet manufacturers. Since the Hornady HP/XTP is similar to the Nosler JHP in that they are both jacketed hollow points, I guess I'll use Hornady's load info... |

Yeah it does, you generally don't want to use JHP data for FMJ or SWC bullets. What is your reasoning for not using JHP data for FMJs? The only thing that you need to consider is that bullet may seat alittle deeper in the case on a JHP of the same weight FMJ unless the JHP has a thin jacket. Obviously loading a LSWC is a different story. |

Different bullets although they may be the same in weight will create pressure according to how long the bearing surface is. So to be safe you can not always just go by the weight from one to the next.
I have an old 45 acp. load map from midway that lists loads according to bullet type, weight, and manufacurer. Takes a lot of the guess work out, but I still begin at the suggested starting load. |

I understand about the differing bearing surfaces but there is no way the starting load for a FMJ will be even close to max for the same weight JHP bullet or vis versa. |
