Ruger LCR...Cylinder dirtier than barrel

[woodco]

:roll:
I purchased a new Ruger LCR and just finished firing 50 38 sp.
rounds through it.
The accuracy was good. The fouling was more noticable in the cylinder holes than in the barrel.
I also have a Ruger GP100 357. I never noticed that much more fouling in the cylinders than in the barrel.
Anybody have any ideas as to why??
Thanks

DIRTY CYLINDERS ON MY LCR....

Did you shoot commercial short-barrel loads or something appropriate to barrel length? First guess, if reloads, is too slow a powder or too light a load.
