Wayne-I'm a bit leery of brass stretching. It seems to me you gain length while you loose somewhere else, specifically the head and that's not a good place to loose brass. Moreover, the cost of such equipment is several times more than just trimming the 45-90 brass.
Kitch,
If you read the article you'll find that neither of you assumptions are correct. The brass is not stretched in the head area and for around $40 you can pick up a case stretcher.
