overall case length question

[Cal Sibley]

You may have opened a can of worms. Firstly you may not even be able to reach the lands. Todays chambers are very long. Each bullet will have a diffeent maximum OAL. One bullet is rarely the same length as another type and weight. Additionally not all bullets perform best when seated into the lands. Some acually prefer a jump to get there. I use a Stoney Point OAL guage and find it works quite well. You want to merely kiss the ogive lightly, don't force it or you run the risk of very high pressures which can be dangerous. Take your time and regardless of the method employed in finding the maximum OAL length, make length adjustments as required to find the best length for accuracy. Best wishes.
