Some rifles 'tune' better with one or the other. In other words, they may be practically the same performance-wise, but if your rifle shoots one in 1/2 MOA groups, and the other in 1 MOA groups...
That's the same reason there are so many .22 cal varmint and target bullets in such a small weight range. 50 grains, 52 grains, 55 grains, 60 grains. All flat base hollow points. Not that there's much (if any) ballistic difference, but some rifles like certain weights better than others.
