Looking for a source (or if you want to share) for some basic 38 spl loads loaded in 357 brass. Want to try them in my 357 S&Ws before I go commit to a Marlin lever action. Will be comparing them to similar loads in 38 SPL brass.
TIA!

So basically, load on the upper end of 38 or lowest end of 357 to get mid range 38 in 357 brass?

For a lot of powders, there is a gap between where 38 special ends and 357 magnum starts. You would end up in that gap probably. My Lyman manual lists a max of 6gr of Unique for a 125JHP, and 357 starts at 7gr for the same bullet. In that case, I would try some at 6.4 & 6.6.
With a 125gr XTP, Hodgdon calls for a 4.6gr max (up to 5gr for plus P), but 357 starts at 6.8gr. Here, I would probably try some at 5.1gr-5.2gr and a few more at 5.5.

Depending on powder and bullet weight I usually use the starting 357 mag recipe in my loading manuals. Some will come fairly close to 38 Special loads. I use the Lyman, Hornady, Hodgdon, and Alliant manuals a lot. I did that with Bowling Pin shoots and with high number of rounds kept the cylinder carbon rings out.

EXACTLY. Load at the ragged edge upper limit of the 38 special charge in the 357 and the extra 1/8" length (case volume) will lower the pressure and fps right down into the mid-38 special range.

Yes. You can load 10% more of a regular 38 special load data. Essentially you are loading +P ammo or even +P+ in the 357 brass.
If used a regular 39 special load in 357 brass you would have a under powered mouse fart load.:D
