[QUOTE="supercrossbmx69, post: 928488, member: 29593"] I tried the sharpie trick and it didn't work well for me. Try this, back your seating die way out and seat a bullet in a case. Stick it in your chamber and your bolt more then likely won't close. So twist your die more and more until your bolt closes. Take the case out and take some 0000 steel wool and polish the bullet. Stick it back in the chamber, extract it, and you should see all the marks of your rifling. Keep doing this slowly, (1-5 thou at a time) polishing the bullet every time you pull it out of the chamber until the rifling marks dissapear. You now have your OAL. In my opinion this is a way more accurate way to find your OAL then the OAL gauges that you screw into the modified cases because they do not take into account the amount of pressure put on the case by the bolt face when it is closed. Hope this helps. [/QUOTE]
