Ok, here's the magic.
Go to google and searche for SAAMI max pressure for whatever cartridge you are interested in loading for.
This page is decent and has a lot of them in PSI.

Then check the manufacturer load data for the powder you are using in the cartridge you are laoding. They will list a pressure for their max load. Verify this pressure is in PSI. If not revisit google and CUP into the search terms as that is the other unit of measure for cartridge pressure.
9mm luger is 35,000 psi
+P is 38,500 psi.
Often to load +P you need +P brass, which has a thicker web to the cartridge, and thus different internal pressure curves, and different reloading data. Fortunately for 9mm, this is not the case.
Then you should hit up forums and ask around about how the powder behaves with temperature changes, or invest in some internal ballistics software which can make a decent guess at such as well as pressure curves with increasing charge. Some powders spike badly past a certain point.
Then you get a decent powder drop and a reliable scale, and a chrono in addition to the other basics for reloading.
Then you start with a reduced charge and work up very slowly and inspect fired cases keeping a very close eye pressure signs.
As far as bullseye being appropriate? It has load data for 115gr FMJ but not hollow point. It doesn't mean you can't use it for a JHP, as two JHP bullet profiles are likely not the same anyway. However, That fact is one of the reason most load data doesn't go to the ragged edge on pressure. Most powder drops will thow a charge off by .1 grain often enough you ahve to pad for that, and some bullts take up more case space than others, so they have to allow for that too. That's why whenever I get some different bullets in for reloading, I keep track of their dimensions for fufture reference.
Bullseye's max load for a 115gr FMJ is only 31,000 PSI, I suspect that means it gets non-linear at higher pressures and should be used with cuation. Fast powders ina small cartidge tend to be unforgiving.
Working up your own high pressure loads is NOT for people who aren't very experienced at reloading and who have a gun they don't mind blowing up.
