COMPUTING LOAD DATA
There are a couple of sources (books) that help a reloader develop loads for cartriges that are not listed in common reloading manuals. I need to work up a load/loads for the 338-375 Ruger. Available info has been sketchy at best. I want to get it right, as anyone that reloads can understand. Any help would be appreciated. Thanks in advance.

If it was mine I'd be looking a full case or mildly compressed lit by a mag primer. I would also try and find a ball type powder, H870 maybe. How does the case capacity compare to a 340 Weatherby Mag? Remember that Weatherby's are long throated, other chambers require a powder reduction. 0 -
358 Norma mag. data will get you into the ballpark. Your loads wills end a little better than the old Norma load. Many variables to consider, so start low and watch for signs of trouble. 0 -
If I'm venturing into unknown waters, I run the numbers through a Powley Computer (slide rule) to get an idea of starting load and powder. 0 -
Had a Powley Computer/slide many years ago, but we have moved around a lot and it is probably misplaced somewhere. Have checked out some of the available download programs that might be useful. Thanks to all for your feedback.

Quickload is the modern computerized approach to dreaming up loads.
They don't give it away, though.
