The Honady tool as mentioned above works okay and will get you in the ball park but it's better to use a case that's been fired formed in your rifle. When you're measuring in the thousands every little bit counts. Go ahead and split the neck of your fire formed case and try that. If you have a drill press and a tap and die set you can make your own fired formed case comparator to use in the Hornady tool.
BTW, there is nothing wrong with kissing the lands or running reloads that are jammed. Who knows, you may find your groups getting smaller.
What caliber are you reloading, weight/manufacturer of bullet and rifle you're shooting?
