Exactly! Never trust any of us! Some of us are secret foreign agents that are trying to blow up Americans one reloader at a time!
Just kidding but it is a very true statement that ArchAngel has made. Being humans, we can make mistakes too. The "checks and balances" in this hobby is knowing how to find that data for yourself, then asking for suggestions.
Each of the powder companies have their own data website.

Alliant Powder - Reloader's Guide
http://data.hodgdon.com/main_menu.asp (Hodgdon, Winchester & IMR all here)
Vihtavuori-Lapua.com
There are also sites that are dedicated to providing reloading data.
One is called handloads.com, no subscription needed. Another is loaddata.com, this one requires a paid subscription but is WELL worth it. The data provided here comes from all of the powder, bullet and manual publishers but also includes the data tested in Handloader, Rifle and Successful Hunter magazines. Somewhere in the neighborhood of $30 for a year.
Those are some links you need to save to your "Favorites" folder.
Hope this helps.
p.s. Bullseye is a superb powder for both of the calibers you listed. It is the first powder I ever used and will make some wonderful target loads for both the 45ACP and the 9mm. If you want +P or magnum type loads though, it isn't the powder to use for that. In this case, or rather in either of the cases you are trying to load, too much of a good thing is a bad thing! If you get my drift.
Have fun, be safe!
