My Rem. 700 CDL has a very short throat,so I have to be extra careful loading for this rifle.I take a case that has been fired in the rifle,dent the neck just enough to hold the bullet,chamber the round with the bullet seated long so it will contact the lands and slide in for the max length touching the lands.I usually set my die to seat the bullet around 20 thousands shorter than that length.With 165gr Hornady Interbonds my COAL is 2.868.With a 165gr Hornady SP it's 2.815.So you can see the COAL is quite different with different bullet shapes.This is why I find the lands and seat in 20 thousands from there to start my loading.
