Do you  use same specs for Hornady 185 gr JHP?
If so what powder & and charge would be a soft
shooting load? I have Bullseye,TG,WST,#231&Clays.
Just one month less than a year of open heart
surgery DR said I could start 45 with light loads
two handed at 50'&75"
One 0ther question do you push on nose or use a seater
that pushes on the side?
I do have a soft load for my lead 185 Stars just wanted
to The Hornady as I have never shot JHP
Sorry for long post
Thanks

Hi Lamar, I load the XTP after getting bad batches of zero and nosler in the peak of covid.

These cycle my Pardini GT 6" with an ultradot2 on top

185gr Hornady XTP
1.225" COAL
4.25gr VV N310 for short line, 4.5 for long (there are many threads that compare proper BE vs N310 weight - it's pretty close IIRC)
0.469" taper crimp
Winchester Large Pistol Primer

I have also played with the 200gr and 230gr XTP. I like the 200gr XTP at 25 yards and I have a B16 center shot in a match with 3 Xs and 3 solid 10s so I think it's still as accurate as the gun and more accurate than I am

200gr Hornady XTP
1.235" COAL
4.05gr VV N310 for short line
0.469" taper crimp
Winchester large pistol primer

The 185 load I measured with labradar at around 770fps btw, the slowest I could get the gun to run reliably with the dot on the slide, sometimes with the case seeminglyrolling down my trigger finger onto the table. With my iron sight slide it throws the brass much further.

The Hornady 185 jhp is an excellent bullet!
You have to load it slightly longer because the bearing surface is shorter.
About 1.230 as I recall. To shallow and the crimp will force the bullet into the case.

Thanks again

4.2 - 4.6 gr WST is a good load in my guns when using the ZERO 185 JHP-C or the Nosler 185 JHP. Note that ZERO makes two 185 JHP bullets. I think the JHP-C is the catalog 187 and the JHP is catalog 185. I get best results with the 185 JHP-C bullets #187. They are most similar to the shape of the Nosler 185 JHP. I think these are points worth clarifying.

Again, Dave Salyer and Al Doorman developed the "Marine Load" using the Nosler 185 gr. JHP. Dave told me that the COAL was found not to be critical in regards to accuracy. Of course, it must be short enough to function in your magazines. I don't remember exactly, but I think they settled on 1.25 COAL for the Nosler 185 gr. JHP in the 45 ACP cartridge.

According to the SSUSA article, the Dorman/Lawless load was:

The Dorman load was put together on a Dillon progressive press using: New Winchester primed brass, trimmed to a consistent length; the relatively new Nosler 185 grain JHP; 4.1 grains of Vihtavuori N310 to a loaded cartridge overall length of 1.20”.

The article does say that the Marines got the same accuracy with once fired Winchester brass. Dave Salyer told me about the VV N310 powder, but said that they found the Alliant Bullseye load was close to the accuracy obtained with VV in their machine rest tests.

I thought I was the only one just removing the flare (at .471-.472). I also go 1.215” with the Zero JHP, but I have to plunk test. One of my match guns is tight and will not accept that little of crimp (about 1 in 30). Those end up being fed through my mil spec range gun.

They should drop into the chamber with a “ plunk” and land flush to the end f the hood extension. I say that because guns can be throated differently; you don’t want to jam into the leade or rifling. In 556 rifle they say don’t dare load too long..that short bullet jump kills a nasty pressure spike and allows the shell to center up properly instead of being slightly canted in the chamber.
