I am looking at this bullet to reload for my Blackhawk.

Having trouble finding load data for it.

Is there a good website for this?

Thanks

What kind of powder / primer are you planning on? I'd just use 140 grain data and be a little more careful near max. 2 grains isn't a huge deal. Let me know what other components you have in mind, and I'll give you what I can...

Here's a good start, anyway...

The only powder I have is Unique.
What powder is best for 38 spec and 357 mag jhp and fmj?

My primers are Remington No. 1 1/2.

Thanks for the input.

Unique is a great powder for both calibers. Speer used to make a 140 JHP. Some of their older manuals will have data for it. If you need data now, you can use 158 jacketed data.

Unique is a good powder for sure. Top end loads for .357 mag will be with 2400, Blue Dot... something that burns a little slower.

You can always use heavier bullet data for lighter bullets. So start w/ 158gr powder charge of your choice & work it up. If you have an old Speer manual, they have data for their old 146grJSWC, should be fine.
