That is quite typical of the flat twin or boxer engine configuration for two stroke engines. The left cylinder winds up with a un-natural air-fuel mixture flow through it, which causes that cylinder to run more lean. You have to richen up the mixture more as a compromise in order to keep both cylinders running OK. Thus one side runs more rich and the other side tends to be more lean. You can alleviate the problem by flipping the left cylinder around so the exhaust faces up while the right cylinder exhaust faces down. That then has the air-fuel mixture flow through the engine come out about the same. Then the two cylinders run much more closely together for temperature. But people tend to consider the engines more ugly looking like that though.

They have some videos up on Youtube. The guy who fired the .600 Nitro Express was in for a shock. The video of the guys firing the monster guns like the .577 Tyrannosaur was almost comical with the pain it was producing.

Of course it is totally off the wall but a company actually makes revolvers (handguns) that shoot the .600 Nitro Express too.
But carrying a 13.5 pound revolver on your hip is not going to work for very long. Of course it might be handy for thick brush where you might walk up on a bull elephant or a Cape Buffaloe in a bad mood, or maybe that T-Rex that just snuck up behind you.
