I JUST CHECKED FIVE[5] MANUALS. They ALL had minimum woossy loads such as you speak. THey also ALL had those same loads at the minimum pressures the propellents can be safely be used at by handloaders.
I note you mentioned JACKETED bullets in the same breath with those low-end, low-pressure loads. When you stick the first one of those in your 38 BBL pay your pistolsmith to remove as you'll probably ruin the BBL doing it yourself.
The ONLY safe loads such as you want will be with lead bullets and the ONLY ones of those that'll deliver some semblence of reasonable ballistic performance will be the 38 WC bullet that were designed 80 years ago to do just that. AT THAT, they tend to shoot their best with full-charge loads, not the mid-range loads everyone has used at Bullseye shooting since moses was a corporal. By the way, you can get these down so low that firing residue dirt-in-the-BBL can stop one of 'em dead in it's tracks. You'll not need the pistolsmith to knock out the LWC's though.
