BULLET SEATING
HAS ANY OF YOU ALL HAD ANY PROBLEMS GETTING YOUR BULLETS TO SEAT THE SAME DEPTH EVERY TIME?ON MY RCBS DIES,I CAN SET IT AT THE DEPTH THAT I WANT AND LOAD 5 SHELLS AND THEN MIKE THEM AND MAYBE 2 ARE THE SAME AND THE OTHER 3 RANGE FROM .002-.008 DIFFERENCE.I CHECK THE SEATER PLUG AND DIE TO MAKE SURE IT IS FREE OF ANY MATERIAL.COULD THIS BE A DIFFERENCE IN THE FACTORIES BULLET MOLDS,WHERE THE OGIVE COULD BE TAPERED A LITTLE DIFFERENT ON SOME THAN OTHERS PACKAGED IN THE SAME BOX?I DON'T KNOW,JUST INQUIRING IF ANYONE ELSE HAS THIS PROBLEM.

<Bill>Assuming your dies are tight and you use a full stroke on your press everytime, the OAL's may be closer then you think.
Try using a comparator that measures the bullet from the ogive, rather then the tip.
Many bullets such a soft points may have lengths that vary ever so slightly, these tools allow for a more accurate read on OAL.
Chances are that your OAL's are closer then you think.

<Jeff in ND>Assuming you are meausring off the ogive and not the bullet tip (the tips will very) it could be a neck tension problem, espically if you are using the S-type neck bushing die. I ran into the same thing a while back and finally determined I did not have sufficent neck tension and the powder charge (a slightly compressed load) was pushing the bullet out a tinny bit on some cases. I changed my neck bushing down .001 and the problem went away.
Good Shooting

<Gary Rihn>I'm with Bill on this one (although Jeff's point is valid). Take a handful of bullets & mike them before you load, you'll see a slight difference in length on them.
Try measuring your loaded rounds with a comparator & see if they check out better.
