I've shot lot of light bullets through a lot of barrels, and in my experience it takes a HOT barrel and a very thin-skinned bullet ay very high velocity to cause problems.
And sometimes it happens in a cool barrel with standard weight bullets. Several (too many) years ago, I was working on new loads for a 22-250 in Rem 700 varminter with a standard twist heavy barrel. The bullets were some double hollow point 50 grainers from Jim Calhoun. The groups were clustering OK when all of a sudden there were no more holes in the target for the next powder increase. It turns out the bullets were coming apart in mid-air, and those small dust clouds downrange weren't dust at all. Of course, on the outside of the box, Jim had printed on the box "Not for velocities over 3600 fps", or words to that effect. But hell, what guy ever reads the instructions...LOL
