My magical 38 Special accuracy load is :
Lyman # 358432 - 160 grain or the NOE reproduction 358-160-WC, both of these are 160 grain button nosed wadcutter bullets. cast and sized .357 or .358 , makes no difference in my guns.
with 2.7 grains of Bullseye , in 38 Special case and crimp into the crimp groove.
A 25 shot group at 25 yards will make one ragged hole 1 1/2 " across, that's from a rest and a model 64 S&W set up for target shooting.
I have found no other load/bullet that will better this one and I've tried many .
