Re: 38 special loads
W231 or Bullseye works great. I use W231. I have experimented with different charges and usually come up somewhere between min and max.
Hornady makes a big box of HBWC 148gr bullets that are cheap and extremely accurate. The WC design cuts a nice hole in paper.
Seat the bullet flush to the case mouth.
When all is said and done, there is a lot more said than done.
