The loading manuals are full of +P and baby magnum loads for 38sp. I would guess that there are more bullets and loads for the 38sp than any other cartridge.
To me anything that is not accurate is not interesting. I’ve loaded a lot of revolver ammo and load only one heavy. It’s an old Ruger SBH. It’s running 22.5gr 2400 over 240JHP. Why you ask? Because that is it’s sweet spot or it wouldn’t be cranking that load.
We have a few locals known for blowing up firearms. Do what turns you on.
I don’t think anyone gives the slightest hoot what others do or think. One thing for sure I’m not in awe of somebody hot rodding their 38sp.
