38 super accuracy loads

The starlings arrived  a few dats ago in the Po valley,usually after their arrival, we have to endure only one cold perturbation before spring weather. The snow has meted. I am loading buckets of  9x21 and 38 super in my 911 clones, an STI Spartan and an Auto-Ordnance Thompson pistol-, I use both the Lee molds ( six cavity)you have. I use old wheel weights ,range scrap and a mix of plumber's lead with a little lynotype . The round nose passes through an RCBS lubrisizer,The TTL  is lubed with XLOX from LESTUFF  and a Lee push trough die. Quenchig them all in cold water ,directly from the mold. And sizing bouth to 357 .. I use air cooled bullets in the same  for light Cow-Boy Shooting 38sp loads. My 9mm bore auto pistols lead horribly with soft alloys. I have normal issue recoil springs, because with reduced power springs the pistol won't shut the slide reliably . I use Granular Cheddite Grossa,which is a single base shotgun powder ,similar to Red Dot and PB in relative quickness. A little less than 5 grains in the nine ,more in the 38 super. Any fast  economical shotgun powder made for 30- 32 grams of shot in the 12 gauge will do.  It must meter  reliably through  a Lee  powder disk measure. All are loade in a Dillon 550 with 4  Lee dies ,with factory crimp. I sit in a position who lets me spot a double charge in the hulls. Safety first.  I use the lowest weight that reliably cycles the action . You have to do a lot of experimenting and load development in your gun.That is half of the fun. The 38 super accepts  38 revolver bullets with any nose configuration and they reliabily cicle the action , consider what your goals are you have a GREAT lot of work to do, I should say an endless pleasure.  I use a velocity around 1100 fps wit a power factor around 130 that is correct enough for fun shooting at steel plates. This combo shoots decently and does not lead the bore and I can shoot over 150 rounds without cleaning.   My goals is  economical fun shooting at reactive targets ,with minute of steel plate accuracy without leading and dirty pistol stoppages.
