How precise do calipers have to be in reloading? I have a Neiko digital caliper but the jaws don't shut all the way closed, they stay open about .003 to .005 of an inch, would it hurt anything to just add the.003 to .005 to every measurement when zero'd out? I got it last year in April so I don't have any purchase paperwork and it is supposed to have a one year warranty, should I press the issue and try to have Neiko replace it? I knocked off the reloading bench a couple of times, do you think that caused this situation to happen? Thanks. 74man
