This rifle was built on short notice, when the owner of #3 said we needed another one to take to Africa. "We" now included me! It was basically built as a rebuild of a factory Winchester Extreme Weather that I had bought a couple years ago, that just didn't perform like a rifle owned by a custom rifle maker should. In fact, compared to how others have reported on the Extreme Weather models, I would say Winchester made a dud. A 3" group dud.
The factory barrel was replaced with a top end cut rifled barrel from a Brux blank, and results were outstanding. I will say that the receiver machining looked very nice on this FN made Winchester, and the build was done without any re-machining on the receiver.

| For the Winchester M70's claw extractor, a groove needs to be milled out of the barrel tenon. With a quick change-up the Haas TL1 makes a suitable 2 axis horizontal machining center. For this use, I would argue that it is as solid of a setup as you could ask for. |
