Anybody make an autoloading rifle in 10mm? Sort of like the Ruger PC4 Carbine but in 10mm instead of .40S&W?

I don't think that there are many rifles out there that are chambered for the 10mm cartridge, aside from the ones mentioned above. Most of the weapons chambered in 10mm were handguns (Glock, Colt, S&W, Bren-Ten)

HK did make a version of the MP5 that was chambered in 10mm, called the MP10. I don't believe that it was ever available to the public.

If you really want to get fanciful, there is the M41A pulse rifle from the movie Aliens. It was chambered in 10mm. ;)

I have been thinking that a Winchester 94 with a 16 inch barrel in 10 mm would be great. But I do not know if this is even feasible. It would make a great light carbine that shoots a decent cartridge.
 
Reloading for 10mm is only slightly more expensive than reloading for .40 S&W. Same bullets, large instead of small primers, slightly more powder, and a the big differance: More expensive brass. Range pick-up is unlikely but I found about 200-300 spent Federal cases at the range about a month ago. I'm glad I didn't pay for all the factory ammo they came from :uhoh:
 
D-Max

D-Max came out with a 10mm carbine back in the '80's. The magazine fed from the side like a Sten. It had a perferated barrel shroud and black crinkle paint on it similar to a Sterling.
 
The feds converted some of thier Thompsons (yes, they still have a few) to 10mm before they convinced H&K to make one. That 10mm is the main reason H&K offers a 0-1-2 trigger pack, full auto is very difficult to control and batters the receiver. Lot of energy there, in fact that Oly Arms upper is gas operated!
 
The Thompson was developed at the FBIs request to test the feasibility of the 10mm cartridge in a sub-gun format, but they were never actually considered for actual issue.

The Olympic Arms 10mm carbine no longer uses a gas system.

The HK MP5-10 employed two different bolt carriers which they termed a "high impulse" and "low impulse" carriers. The low impulse carrier was for FBI Lite style loads while the high impulse unit was for full power loads. Apparently HK could not develop a single unit that allowed both cycle reliability with lite loads and yet still kept battering under control with hot loads.
 
So far it's fed, fired and ejected everything I've loaded in the mags, but I don't think I'd ever use it as a "duty gun." The ejector looks more like a modified paperclip and doesn't fill me with enough confidence to bet my life on it.
