Like Graphicart said.

Don't download it below recommended levels or it might go boom. But there is loads of data for it, particularly if you want to shoot high power jacketed loads.

For cast, the Lyman cast bullet handbook does have data for it going from 200 Grn Cast 25.1-27.7grn for 1327-1482 fps
to 310 grn Cast 17.5-19.5grn for 977-1092 fps

Magnum primers and a 4" barrel so expect a 12" barrel to be a fair bit faster.

If you get it, let me know what bullet you are using and I'll look up the exact load data. You might need gas checks to.

Expect everyone shooting around you to be thoroughly annoyed by it.
