am in no way a collector. Just a shooter.
If 7x57 brass were not unobtanium at this point, I might put in a bid. Even though I have put 7-08 barrels on a Rem 700 and on a 7 at this point.
There is plenty of ammo in 7x57 available.
I have not bought a single round of loaded centerfire ammo since 1982, and only then because I had bought a new rifle while working out of town for a month.
I am presently needing 100 cases to load for a 6mm. All the typical suppliers, Grafs, Natchez, Midway, Starline, Midsouth, had nothing available in 6mm, 257, 6.5x57, or 7x57 as of last week. Except for niche suppliers like Nosler which they want near $2 each for.
Midway says 7x57 is "coming soon". I asked to be notified.
If one has a source for brass which can be necked to 6mm, at a typical price, I would love to hear it.
