OAL is generally given so that your ammo will fit into any rifle magazine. It is not nessasarilly the best dimension for your gun. I try and seat the bullets at about .035" from touching the rifling. Several guns I own wont allow me to do this because of deep chamber throats. If you are going to use these in a magazine then you will most likely have to abide by the OAL spec in your manual. If not you have much more room to "play" with the OAL. Oh, Yes the OAL printed in the manuel includes the tip. KN
