Does ANYONE have data for 45 JHP (Zero) using Winchester AutoComp for bullseye?
I understand it is the old SMP224 manufactured years ago.
My are starting to bleed looking for data.

Oh, man.... I've never even heard of the stuff, and I go back a long way.

Here's what I would do:

You don't really need data for target work, you just want to avoid blowing yourself up. Sooo, consider the stuff as Bullseye and use data for that. I know that's not what you're asking, but at least you won't kill yourself.

You'll probably find the accuracy you want somewhere near those loads. If not, it's not want you really want. Sell the stuff on line.

have you looked at http://www.wwpowder.com/pistol.html?

According to this chart which bases different brands into close equivalent's that powder is not listed, so guess I would start with light loads of no more than 3.5 gr and work up.

Burn rate info

(Knew I had that around somewhere)

Looks slower than just about anything I've seen used for bullseye.

(edit:) Even better: the Hodgdon Reloading Center shows a starting charge of 6.7gn at 856fps for a 185gn Hornady JSWC. (Please verify for yourself, don't blow yourself up, treat reloading advice on the Internet with caution, etc.)

Rogerj,

Have you tried calling the Sierra Bullets Reloading Technicians? They may

have what you're looking for. They can be reached Monday through Friday

from 8:00A.M. to 8:00P.M. (CST) at 800-223-8799. The data is provided

free of charge. Good Luck!

Thanks to everyone for all the responses.
I have checked the reloading sites....still in process.
I am now a brunt of a few jokes with some I know. However, I am going to get to the bottom of this. I'm shooting 25 and 50 feet indoors. Just how critical is a few grains +/-? LOL on the humor/ seriousness of blowing myself up. been around a few 24hrs and exercise caution at all times when reloading.I looked at a site that also listed the 6.7 as a start. For a powder (SMP224) that has been around (called AutoComp now) there has to be some data to compare the numbers.
This is the best site to get answers, in my opinion.
I'll check each suggestion given.
Be safe.

Just to clarify my death and destruction post: if you start with loads from the fastest powder out there (Bullseye), you won't be in any danger of a too hot load. If the powder seems unsuitable when doing that, it's probably too slow for your application (the lightest possible load that does the job). This DOES seem to be the case with the data shown.

Sorry double post, see next post

Should be easy to figure out, here it is straight from Winchester, but really hogden as Winchester doesn't make powder they are just a licensing name.

For a 185 fmj, they say 6.7 gr, to start but that's overkill for bullseye and at 25 and 50 feet way so, id try 5.5 to start and see how good it works. Set the OAL at 1.200, crimp to .469 if this doesn't cycle the gun then bump it to 6 grs that should do it.

Great reply.
There is hope.
Now I have a logical starting point to get to where I need to be.
this should be a very interesting adventure to get where i need to
be for shooting another type of ammo for Bullseye.
Thanks so much. I'll post my results when i compile them.
