Re: problem with bullet seating
[ QUOTE ]
I have a redding competition bullet seater and I am getting about .2 variance in seating depth when measuring from the ogive to the base of the brass. Is this normal or did I get a bad die. the load is: 308 win. Lapua brass, 44 grains of varget, and a 178 grain A-max thanks in advance for your help.

Do you mean .2" which is over 5mm or do you mean .002" (two thousands of an inch), the former is a vast amount , the latter almost de minimus.
Manufacturing tolerances on individual bullets (dependant on the particular press tool each bullet came from) will readily span 2 thou or more as has been said above, setting a seating die to a given depth will often result in a slight tolerance difference in O.A.L from round to round often no more than 3-4 thousands of an inch, this is normal and should not affect accuracy, this is why a measurement is often taken of the ogive with a seating comparator rather than across the meplat.
If indeed you are correct with a discrepancy of .2" then indeed something major is going on and needs sorting and as a start you should look at the seating die.
As you say you are getting variance in seating depth I take that to mean that some of the rounds you seat are to correct length, this being the case I can only summise that nothing major is wrong with the die and that the dimension .2" is indeed a typo and should read .002" which is to be accepted as a manufacturing tolerance on the bullets.
Forgive me if that is the wrong interpretation but that is my guess from the information you give.
Hope this helps
