I need to use up some Hornady 230 grain XTP bullets in my Ruger Blackhawk 45 Colt and I'm not finding a lot of useful loading data for this bullett from the manuals I have and some of the better internet sources. I want to develop the load to produce a minimun of 1000 FPS.

The powders that I have on hand to use are:
IMR 4227
2400
Unique

At this point I'm leaning toward using 19 grains of IMR 4227, based on some of the data for bullets in the 240/250 grain range.

Any suggestions would be appreciated.

You "need" to use them up? Sounds like going to the dentist.

Send them to me--I'll give them a good home.

You might try calling or emailing alliant and/or hodgdon. I've done this several times with good success.

4227 is going to be too slow for pushing a 230 Gr bullet at 1000 FPS in .45 Colt. Unique may do it. If not, 2400 will.

There is no crimp groove on the 230gr and that`s why no one used it in their data manuals. The bullet is designed for use in the acp not the LC. If you do use it a taper crimp is a must.

Both the current Nosler(#6) and Speer(#14) Manuals show 230 gr bullets being driven over 1000 fps. I do not want to quote specific loads because they are maximum loads and should be used with discretion.

The reason you are not finding data is because the 230 grain XTP is a .451" bullet for the .45 ACP pistol.

The .45 Colt normally uses a .452" bullet that has a crimp cannelure so you can roll-crimp them for use in a revolver.

IMR 4277Sure it isn't IMR-4227?
At any rate, 19.0 grains of 2400, or 20.0 grains of IMR-4227 with an undersize 230 grain bullet should be way safe in a Ruger Blackhawk, and get you in the 1,000 FPS neighborhood..

In a Blackhawk you could use at least 10 grains of Unique and would probably be around 1,000 fps. That would be a nice round for shooting and I don't think it would disturb the other rounds in the cylinder. If you want to smoke something then I would go with 2400. As Ol'Joe said with no crimp groove you probably don't want to go "hot" as the bullets in the cylinder may unseat.

Thanks for the all the feedback. I think I'll go with Unique and a good taper crimp as jmortimer suggested.

For comparison, I recently tried using IMR 4227 in a 45 Colt. 17.7 grains, 250 gr. LRN with WLP primers in a Smith model 25 with a 6.5" barrel. Recoil was similar to a 44 mag. Accuracy was decent, considering the recoil. You might try some if you like experimenting, but be ready for a hard kicking round.
