I usually add "standard reloading cautions apply when using this data" or something similar when responding to a post asking for specific load data.
As for reloading manuals, data sometimes changes from edition to edition. I ran into an example with Sierra data. OAL on a 9mm load decreased by .090 between one older manual and a newer one, same bullet, same powder charge. I querried Sierra and they said different ballistician developed the data and they stood behind it. I figured seating a bullet .090" deeper would raise pressure a good bit over the old oal.
