Chard: I have been using Remington 221 Remington Fireball brass for over two decades myself and I have as yet to encounter my first problem with it.
I use it in two factory Rifles (Kimber Ultra-Varmint & Remington 700 Classic) chambered in 221 Remington Fireball and in a custom Rifle chambered in 17 MachIV.
I also have a Remington 700 VSF in 17 Remington Fireball that uses Remington brass.
All these Rifles give excellent accuracy and the brass is long lived and without fault - that "I" can find anyway.
Speaking of finding it - I have had NO problems in that regard either!
The Remington Fireball brass lasts so long (with MY reasonable loadings!) that I rarely have to replace it.
When I do though I usually buy my 221 Remington Fireball brass through Ron Kesselrings wonderful gunshop in Burlington, Washington - Kesselrings Gunshop -

As one example of the accuracy I get with Remington 221 Fireball brass I will cite the last four groupings I have made with my custom 17 MachIV heavy Varminting factory/hybrid Rifle (weighing 12 pounds 11 ounces) - these are 5 shot groups fired at 100 yards - groups: .264", .339", .322" & .262"!
Nothing wrong with that brass, accuracy wise.
By the way those groups were all fired in different but consecutive years for sight in verification, using a Leupold 6.5x20 variable scope.
The FIRST "on-line" site I just now checked for availability of Remington 221 Fireball brass had a virtual unlimited supply of it in amounts from 20 pieces on up through lots of 1,000 and 2,000 pieces!?
30 cents apiece for brass that lasts nearly "forever" is a small price to pay in my eyes.
I thus disagree with your contention that its "hard' to be a 221 Remington Fireball fan".
Long live the 221 Remington Fireball "family" of cartridges!
Hold into the wind
