Looking for load data for MP .452 275 gr 45 carbine boolit.

So my mold just came in today before I have to do a12 hour shift without internet or cell phones fun working a penitentiary.

So I'm looking for some load date as all I can come up with is 260 gr and 300 gr on 45LC. I only have a few powders like 700x and 800x, Win 231 that I can remember off the top of my head.

So any advice? Can I use the light or heavier load data with lighter start at min then go up 10%? Thanks for the advice I'm really excited to start casting this round!

This has come up in the past. There are other threads but I found this one the most interesting.

The .45-08 might be closer to useful. If you can find a case reamer at a reasonable price. Another post suggested cutting down, .45 Rowland brass.

We "kind of" know the loads you're seeking will work. Handloader magazine has done articles on heavy hot loads for the .45 AutoRim.
