I'm getting ready to load some 140gr Hornady FTX in 357mag. As I was checking the Hodgdon load data I was surprised how different the data was between the XTP and the FTX bullets. The starting loads for the FTX is 12gr where the XTP starts at 17.1gr. The velocity is different between the loads as well. Is the primary difference between the two loads how deep they are seated? I'm just curious if anyone has had experience loading both bullets and which shot better

Yes the case trim length for FTX bulltet loading is shorter. For the 140 FTX in 357 magnum cases the trim length is 1.240". Hornady 8th only tested N 105, HS7, AA#7 and AA#9, and Enforcer powders. ONLeY use data specifically for the FTX bullets. Thanks for that information. It wasn't detailed on the hodgdon site. Why would a different case length be necessary? I think i'll work up a load with standard trim lengths. |

I have not used the Hornady FTX/XTP, but maybe phone call to Hornady is in order, they have 800 number so the dime's on them, for the official explanation, because rolling your own ammo is inherently dangerous, it is best to question the "why" part before preceding.

I think I'll work up a load with standard trim lengths. Bullet is so much longer with the pointed nose, something has to give. In this case, Hornady recommends that the case be trimmed shorter. Try seating a bullet and chamber in your revolver. Cylinder won't close........now you know why. |

I didn't have any problems loading these with standard cases and they functioned fine in my 686. The Hornady web site states that you need to trim the cartridges to 1.24" for clearance reasons. The load work-up started at 12.5gr of H110 and ended at 15.5gr. The final chrono results were 1250fps from a 5" barrel. It was really windy so I didn't get a feel for the accuracy yet. I'll load up some more and get better data.
For those of you who use H110 - what is your opinion on standard vs mag primers? I'm using standard small pistol primers for now but would be willing to try the Mag primers if it makes a difference. |
