I know crimping might be wise for a semi-auto like an M1 Garand. But for either a semi-auto or a bolt gun, will crimping help with accuracy because of more uniform and perhaps slightly greater neck tension?
If you are truly trying to reload for accuracy , then crimping will do nothing but deforming the bullet you wish to be consistent. You can figure out what your neck tension you have by measuring , then measure your bullets pressure ring if it has one or the bearing surface. Then measure the inside of the neck and subtract the neck diameter from the bullet and you should end up with .003 to .004 thou neck tension which is more than adequate.I know crimping might be wise for a semi-auto like an M1 Garand.
