By most "accurate", do you mean hitting closest to point of aim, or tightest groups?
My Gold Dot 125 gr +P shoot about 1.5" low at seven yds., group at ~1.5 - 2", my handload 148 gr HBWC's group maybe 1.25"-1.5" (probably should be better, but it's my fault they don't), very close to POA, but as others said, the standard velocity 158 gr go right to POA, and may or may not group as well, depending on the components used.

For grouping, take the range out to 25 yds. to get a meaningful test. There, 148 gr HBWC with about 2.7-2.8 gr Bullseye is hard to beat.
However, a 2" barrel gun is hard to group well at 25 yds. with any load for most shooters, compared to a longer barrelled gun, and a 148 gr HBWC at ~750 fps is not a famous man stopper, but is probably the best accuracy load for bullseye shooting in 38 Special..
