[QUOTE="goodgrouper, post: 116174, member: 2852"] [ QUOTE ] And from what I have heard from guys that have shoot out both 6 groove and 3 groove in the same caliber the 3 groove will last longer. [/ QUOTE ] This is not my experience at all. I have had several 3 groove barrels and while it is true the lands stayed put longer, the firecracking associated with a well worn barrel still affected the group size. I simple bore scope session with a 3 groove barrel on a hot rod will show just as much firecracking as an 8 groove barrel but the shooter may still be able to touch his riflings with the bullet. However, that will probably still not save it from shooting worse. I do agree that 5's, 6's, and 8 groove barrels are more gentle on fragile bullets though. Just my 2. [/QUOTE]
