Seafire: I concur with your observation on the long life of 17 Remington Fireball brass (and 17 MachIV brass as well).
Decades ago I had a bench rest Riflesmith build me a full custom 17 MachIV (the 17 Remington Fireballs twin). I chose a 26 1/2" long HEAVY Shilen stainless steel barrel for the Remington 700 action. I added a Jewell trigger and a Leupold 6.5x20 variable power scope. All set-up the Rifle weighs 11 pounds 4 ounces - to say "recoil" is non-existent is an understatement.
This Rifle came home shooting 1/4" five shot groups at 100 yards. It is an absolute joy in Prairie Dog towns, Rock Chuck colonies or Ground Squirrel fields.
It is not especially pleasant to pack out to remote Prairie Dog towns but I have done it a number of times.
This full custom 17 MachIV is only SLIGHTLY more accurate than my all factory stock Remington 700 VSF in 17 Remington Fireball.
Long live the "17's"!
