[William T. Watts]

Use one of your sized cases and just start the bullet in the case (no primer or powder please) insert the case with bullet in your chamber (with your fingers) until it stops, the bullet is now touching the lands. Take your cleaning rod and push it down the bore until it stops, your now touching the tip of the bullet, pull the cleaning rod out about a 1/4" and wrap a piece of tape around the rod, push the cleaning rod in while holding the case in place until it touches the bullet and mark the tape with a pin. Your loaded round will be shorter than the mark you made on the tape you affixed to your cleaning rod. Your loaded round should be .010" or more thousands shorter than the initial mark you made, a bit crude but this will give you a rough idea about where to start to determine the length of your loaded ammo for your chamber/lands combination.. I prefer H4831 for both the 130 & 150 gr Sp Noslers.. William
