2.5 grains of bullseye and a 148 gr.Speer wadcutter have worked well for me in two 38 S&W’s
Is that a swaged bullet?
Yes, hollow based.
Either the Speer hollow base of flat base. I use the flat base and load it out about 0.2” with q light crimp in one of the lube cannelures. There’s a photo of one loaded in an old Speer loading manual IIRC.
