I'm contemplating getting in to reloading just for my 10mm (for starters at least) and was wondering about bullets. It seems like everybody just makes bullets designed for the .40S&W, but nothing for 10mm. Is this the case? If not, who's making 10mm bullets?

Hornady .400 diameter bullets are marked only as 10mm, unless run super hot most 40 S&W bullets will work depending on what you want to use them for.
I use a LSWC 175gr bullet for both 40 and 10mm and at the correct speed they are the most accurate bullets I have reloaded.

Yep. XTPs are good ten mm bullets. Tough construction. I would also say the 165 and 155 grain Gold Dots will hold together for all but the fastest 10 mm velocities.

A top consideration for wilderness carry is a 200 gr WGNGC hard cast bullet like those sold by Double Tap or Beartooth. These are mean penetrators. DT also sells a 230 gr version, but that seems a bit heavy for my tastes. They also do not stabilize well in a G20 barrel from what folks are reporting.

Lots of people say that all of the bullets out there are designed for .40S&W, and not 10mm, but they are either misinformed, or they do not load 10mm. First, there are the XTPs. They say 10mm right on the box. Not .40S&W, not even .40S&W/10mm. They ONLY have 10mm on the box. So, they are designed for 10mm. Next, there are the Gold Dots. At least the 155gr and 165gr Gold Dots are truly designed for 10mm. They say .40/10mm on the boxes, and they hold up well to full 10mm velocity. Third, we have the 155gr and 175gr Silvertips. The 175gr Silvertips were designed exclusively for 10mm, and are based on the .41/.44 Magnum bullet, from what I've read. The 155gr Silvertip is also capable of handling 10mm velocity, though I think it was designed more for .40S&W (but it works best at 10mm velocity). The Barnes TAC-XP bullets (125gr, 140gr, 155gr) are all more than capable of 10mm performance. There are also the 135gr Nosler and Sierra JHPs that manage to work well even at 1600+fps. Even though they shed mass, their core stays together and continues to penetrate. The Sierra usually retains more mass.

I'm sure there are more out there, but the fact is that there are MANY bullets out there designed for 10mm, and capable of handling 10mm performance. People try to use this as a negative for 10mm, but it makes no sense to me. How many bullets do you need? For human SD, you have about ten good choices (all listed above). For hunting, there are just as many choices. And if you are looking at 10mm for woods SD, there are plenty of heavy hard cast bullets from which to choose. Finally, for plinking, you just use FMJs, and their design does not matter. Get a press, and have a blast!

Good, glad I asked!

If it works to at least 1200-1400fps, I'd call it 10mm designed.

Bear in mind that some plated and almost all lead bullets at higher velocities in Glock OEM barrel lose accuracy because they are too soft. They "jump" over rifling and leave some copper&lead in barrel. They are not stabilized (rotated enough) and accuracy is gone.
When I chrono my loads in development process, there's always a target at 27 yards at the end of sighting line. This target also helps me to avoid shooting my chrono :supergrin:
