The one upside to using a .357 HB bullet is reloading is a snap. I didn't have proper 38 LC brass so I used an ad-hoc replacement; trimmed 38 spl / 357 mag brass, which fits a tad loose.
But the 38 LC doesn't have enough pressure to fireform the brass to the cylinder. So other than de-capping / priming the only thing req'd is a crimping die. I champhered the brass to facilitate bullet insertion, which is easy as the bullets are slightly loose fitting in the thicker ( but champhered ) brass. In fact they can be forced flush with your thumb!
Actually the real PITA is casting the bullets. The thin HB skirt req's a mold at exactly the correct temp; the first time I cast IIRC it was 45 min's before I got a decent bullet.
The thin skirt is much more forgiving with WW's too. My 41 LC HBmold has too thick of a skirt and won't upset the HB into the rifling with WW.
I've 50-100 rds of cut-down brass to give away actually on the EE now.
Get a 310 Lyman in 38 spl and bullets non-withstanding, you are ready to go.
