load for 185 grain XTP

I was hoping that someone could help me out. I found some bullets that I had purchased some time ago and misplaced during a move. I have recently located them and would like to use them. I have 2 boxes of 185 grain hornady
XTP bullets in .45 Caliber and want to load them with 231 my #4 hornady manual list the load for them at a starting 5.4 grains with 6.3 being max. I would like to find out from someone with a newer manual if this is still a good
recipe or has it changed. I only have the 2 boxes so I do not want to buy a new load guide.

It might save you a finger or two if you'd let us know what your loading, .45acp, .45Colt, .45AR?

What are you shooting them through? Specifically, what barrel length?

Nice bullets - good find.

231 is great powder. I use it a lot for 45ACP. And it will definitely work for your application. I don't have my Hornady book with me, but when I get home, I'll re-post. Hornady tends to be "slow powder centric," so I'd be surprised it if lists 231 at all with a 185. We'll see.

Speer #14 has it from 6.6g to 7.4g's.

But if you have a 1911 or barrel length (5") equivalent, you'd be better served by going with a slightly slower powder.

If you don't mind flash, Power Pistol will really send them suckers flying. I'm still in the process of building a P'P'stl load for 185's; but right now, I'm at 8.8g's, yielding an average velocity of 1066fps. I'm not done with this load recipe. Speer tops out at 9.5g's. (COL 1.210"; but I'm not using Hornady's)

Sorry, my only 185g/231 loading is a target JSWC round - a really good one, I might add - but it's only 5.6g's and yields 843fps. There's head room to go quite a bit higher, but there's no point because it's an accurate target round.

If your gun is a short barrel compact, stick with the 231. It pops hard and quick - great for short barrels. If not, consider a slower powder.

Since the 185 gr. XTP was designed for .45 ACP and you're quoting .45 ACP data, I'll take it on faith that you're in fact loading for a .45 ACP: or if it walks like a duck and quacks like duck, it's probably a duck! LOL.

Lyman uses a lower Max Charge at 6.1 grs. of 231 and the pressure rating is a pretty low 15,700 CUP. Don't ask me why, and I just checked my old Lyman 46th edition and they used the same charge with Hornady's older 185 gr. JHP and got the same exact amount of pressure and both were loaded short at 1.175". My SPEER #11 lists 6.3 grs. as the Max. for their old 200 gr. "Flying Ashtray" JHP.

Personally, I'd load it at 1.210" and make about 5 test rounds at various lower charges working up to the data in the Hornady #4. Can't see anything that's changed. W231 is still the same powder and the .45 ACP's pressure rating is still 19,900 CUP/21,000 PSI.

If you want a real ZINGER, look at Ramshot's data for that bullet with Silhouette. A Max Charge of 9.9 grs. will spit the 185 gr. XTP out at 1152 FPS and does it at standard pressure, not +P.

(Oops - I had 230g data posted here. I have since corrected for Hornady 185's)

Hornady #9 has their 185g XTP between 6.5g to 6.9g - narrow window. It's also listed as "HP-38," which is the same powder as W231. COL = 1.213" Max velocity 900fps.

I will be shooting them out of a 5" 1911 either a Gold cup or a PT1911. I forgot to mention that the info request was for .45 ACP . I was quite pleased to find components that I thought were gone and lost forever. I found 100 new primed .45 ACP cases,800 .45 caliber bullets of various weights,200 .44 bullets and 200 .38 bullets. I had given up on finding them a long time ago and figured it was a offering to the moving gods as it seems that I always lose something.

That being the case, might you have any powder slower than W231?

Unique; AA5; HS-6; Power Pistol; or 57K's beloved Silhouette would be better choices.

That 185 XTP is a high performance bullet. You'll want to push it to high performance velocities

In my Hornady #8 book, for the 185 gr. HP-XTP (#45100) and Win 231 powder, it shows 6.4 gr. - 7.2 gr. (max), with COL of 1.225".

Hodgdon's website has the following for a 185 XTP and Win 231 powder:

Min: 5.0 grains, 762 FPS, 12,000 CUP
Max: 5.9 grains, 906 FPS, 15,800 CUP
OAL: 1.135"

The Hodgdon website has the OAL listed at 1.135 for the "Semi-Jacketed Wad Cutter" profile bullet. The XTP's are Jacketed Hollow Points. I would use the OAL of 1.200 for that load just to be on the safe side and see how that performs.

Now this is interesting, Hornady has a completely different load for that bullet with 231 powder. This is just for reference but on page 998 of the 8th edition it list the XTP at 6.4 grains to a max of 7.2 grains at a OAL of 1.225. That seems a little high (hot)

Lyman's 49th list it as 4.4 grains of 231 to 6.1 grains at a OAL of 1.175

You need to work this out for yourself.



Jim

Maybe Brian or Unclenick can pop in and tell us what Quickloads says about these combinations and the pressures they generate.

Those who know my posts, know I'm the last person to suggest a slower powder. I'm definitely a "fast powder centric" (if there's such a term) loader. And W231 is great powder - quite possibly my all time favorite. I've loaded more rounds with 231 than any other.

That said, you'll be doing good to get 900fps from those 185's using 231. You need a slower powder. With the right powder, 1100fps could easily be attained.
