Just for information, I make all my 7 mm Wea. Brass out of 7 mm Rem cases. One pass through the Wea die and my brass is formed, and a bit short so no trimming needed for a while. My Wea is on 700 action so I am able to seat a 160 flush with the bottom of the neck. Last time I checked I was getting about 3250fps with the 160's. Solves the issue of getting Wea brass.
Still the Mashburn has much to recommend it. Probably if I were going to make a new big 7 to day, I would give the Mashburn a close look. Have considered rechambering my old 7 mm Rem to the Mashburn case. It is 1200 plus rounds old, that might give me a "new", rifle without a rebarrel job. The only thing is this old 7 was my late wife,s favorite big game rifle,and I am pretty much a .30 caliber guy.
