    Trim to 1.490 then trim again at 1.495 if your brass lasts that long

    Best if you take the actual MEASURED length of your chamber BEFORE you start trimming. No matter what the reamer length is, most chambers are about .020 LONGER than Max trim length. Measure it, write it down and you may find that you won't have to trim. It also depends on which type of dies you use.
    Full length dies with a neck button will pull the neck longer with every up stroke.
    Shoulder bump dies won't and you can go a long time before you may need to trim.;)

    What ever length you decide, it is best to keep them all the same.
