6.5-284 Norma to 284 Win the correct way

[atl5029]

Would someone please detail the process needed to form Lapua 6.5-284 brass to 284 Win the way it should be done, without any kind of "shortcuts". I am debating on whether to build a rifle in 284 Win or 7 SAUM and I am wondering if the brass prep is worth it since there seems to be no really good factory 284 brass out there and there is good 7 SAUM brass available. Is it as easy as just running the 6.5 brass in a 284 die to neck it up, or is there fireforming involved? As much as I love my 260 AI, I find fire forming to be a major PITA.

I am still using Winchester 284 win cases. (have 600 pcs) If I was starting out now I wouldn't hesitate to buy the new Norma 284 win brass made for Bullets.com

From article in Accurate shooter:
"This custom-made .284 Winchester Brass from Norma is double-drawn for body consistency and the heads are double-stamped for longer primer pocket life. This "special run" brass, created exclusively for Bullets.com, is produced to extremely high tolerances from high-grade raw materials."
