Are you concerned because the longer cartridges won't fit in your mag or because of the jump to lands? I have to be honest and advise that the bullet seating slug can be a pain,there's several thou clearance in the bore of the die and the dimple in the end of lee and all the proprietary brands is needless. My recommendation is to grind that dimple out, if you don't feel competent ask a a machine shop to flatten the end. I did and there were no more issues with a variable coal.
If you do grind the dimple off yourself and make an abortion of it, just turn it round in the adjusting cap. I did that, too.
Lee dies are OK in my book.
