65BR,

Only here at the Campfire have I posted on this rifle.

I bought the WW brass as I was reading where the guys who were winning matches were snatching up "boxed"284 brass.
Not the bulk stuff. I found 200 pcs of it and bought them all.
Those 1000 yard winners were right.

I don't sort the brass and I DO feel that Lapua/Norma is NOT a waste.
That's great stuff. I've used the Lapua 243 necked upfor my 260 for great accuracy and the Norma brass for my 300 WSM.

I just happened to find the boxed 284 win brass.

There are two varieties of Winchester brass, the bulk Win brass sold currently, and an earlier version that was sold in individual 20-round boxes. John Hoover uses the early Winchester brass and he believes it is superior to anything you can buy today. He's done extensive testing with Winchester, Lapua, and Norma brass, and his early production Winchester has always performed best in his family's rifles.

"First step, with new Winchester .284 brass, is to use a Redding full-length die. I screw the decapping pin out of the die and I use Imperial Sizing Wax on the cases. Then I run a K&M expander mandrel to push the 'out of tolerance' to the outside
