[QUOTE="MudRunner2005, post: 1667230, member: 12995"] It can. Over-spinning a bullet can sometimes cause detrimental outcomes, like bullet deformation, spinning the jacket off the lead core, and bullets essentially grenading in mid-air a few yards after exiting the muzzle. However, running a 7mm with a 1:8 twist instead of a 1:9 twist will not cause any issues at all, and will give greater stability, and will open up your abilities to run the full gamut of 7mm bullets. Example, trying to run a 1:6 twist on a .257 Wby (at those velocities) can cause some issues. [/QUOTE]
