If you are into accuracy , like me , you may want to try this.
A 120 - 124 grain , cast lead , truncated cone bullet , like the Lee 356-120-TC or the NOE 358-124-TC-GC (my choice).
I had cast a bunch for 9mm , they dropped from the NOE mould .3575 and I decided to try some 38 special +P loads with 6.1 grains Accurate Arms #5 and taper crimped with the 9mm crimp die.
Fired from an old Ruger Blackhawk , 15 shots at 25 yards grouped into a 1 3/8 inch circle....sort of surprised me ...I'm 67 , blind in one eye and half blind in the other. I have talked to others who have had such results with Truncated Cone Cast bullets and taper crimping. I didn't have any bullets jump crimp. This shook my long held belief that SWC's and roll crimps were best.
A lighter load of 5.5 grains of Accurate Arms #5 grouped into 1 1/4 inches. Might be something for you to try out.
I ran the bullets through a .358 sizing die just to lubricate them but have discovered even when sized .357 they are just as accurate in my S&W model 64 target gun .
