Yes, but what they're made of and how soft/hard they are will play a factor. The big thing is that they're setup properly to begin with. You BBs will eventually soften or wear a groove into the hop, so if it's mounted improperly (BBs flying left, right, etc) then it may not settle nicely. Your BBs should be flying pretty damn straight even before set in begins. But a properly set hop should be good right away as well in general. Depending on the hop material you could be looking at thousands and thousands of rounds before they settle down.
