Max cartridge lenght?
Question for you guys who've determined max overall cartridge length for custom reloading. I tried to follow some unofficial steps on how to do this. Using a prepped case (unprimed & no charge) I started a bullet in the neck. Then placed the round in the chamber and slowly closed the bolt/action with my thumb against the end of the action for a little support / pressure. Then I slowly ejected the cartridge. Did this twice, no stuck bullets and the end result measured the same. I wrote these down but i'm not posting this from home, the rounds were aprox 3/16" longer then the guide sheet from Lee.
This can't be right. Is it? I mean a big caution flag goes up in my mind. The end of the bullet even on the boat-tail / spitzer is still under where the neck begins to taper so the bullet is in the neck, but this just does not seem right. My first thought was the neck was to tight and the bullet is to far up in the chamber. For now I'm continuing to load not exceeding factory max lenghts. But the idea is to eliminate the bullet 'jump' and increase accuracy by taking advantage of the rifle's chamber if I'm not mistaken. Any thoughts or advice on this would be appriciated, thanx. Was I bored or what?
