"Pulling" film involves reducing development...
Adjusting development time mostly changes the maximum density
and somewhat changes the overall contrast. This can be used
(combined with increased exposure when pulling to make up
for the density loss) to move the exposure more into the
shadow area without producing excessive highlight density.
The price is "speed" loss and lowered local contrasts
(and lowered brilliance, if carried to the point where
there are no longer blacks or whites in the print...).
Films/developers vary somewhat in their response curves, so
some respond better to pulling and pushing than others...
I'm not familiar with HP5+, but Fuji Neopan 400 is the
best "pulling" film I've seen - try it at 2-250 in D-76
1:1 with development normal for you for Tri-X at 400.
Amazing, open shadows, but still with good brilliance....

Copy films have different response curves, adjusted to
maintain good whites or for other purposes particular to
copy work...
