All fine and dandy, however Norma is now making Dasher brass with longer necks than what can be obtained by fire forming BR brass. Go to bullets.com to see prints for the reamer like yours and the new Norma brass reamer.

No problem with your reamer and new brass with longer neck
If you want the new brass just trim to length and roll on

Very true, but since he is just starting Out, I thought he may want to take advantage of the longer necked brass. At the very least he now can make an informed decision.

That reamer is fine. I don't mind a little longer freebore in the dashers. You will have to skim some off the necks but thats no big deal. What is your chamber length of the reamer? That can add to your actual freebore if your formed cases are a little on the short side but even so you should be good if you're shooting 105 + bullets. I had a .155 freebore with a 1.555 chamber and it was fine for the 105's.

If we make the assumption the OP has an 8 twist or faster barrel the freebore is fine. If he has a slower twist for lighter bullets then it will be too much.
