Yes, that problem used to be very common, I think maybe less so today but it still crops up. I first encountered it maybe 35 years ago. I bought a Euroarms Remington style revolver just because I was very impressed with it in the store. The cylinder locked up so tight it was like one solid piece of cast iron. But when I shot it on paper the accuracy was dismal. After cleaning it and while the nipples were still out I rammed balls into every chamber and knocked them back out with a rod inserted through the nipple hole. I found that the balls, after being forced into a chamber would literally fall through the bore, not engaging the rifling at all.
I was working in a machine shop at the time and I was able to make up a tapered reamer to open the chambers to .452", which was .001" over the groove diameter. Thus modified that Remington shot several honest one inch groups at 25 yards with a short .454" wadcutter bullet and under two inches with .454" balls. I have since gravitated to shooting .457" balls in my .44 revolvers but no matter how large they may be before loading them they will come out of the cylinder at chamber diameter.
