I just happened upon your post and enjoyed reading it. I have never shot the F-Class, but have thought about it.
In my safe are two 308 Winchester Match Rifles, a 308 M1A, and a couple more Ruger 308's. I love 'em.
BUT, I just bought a Ruger 77 V in the 6.5 Creedmoor. Finally, a batch of ammo showed up, but it is the 120 grain load. Then, last weekend, I picked up a leupold 6.5-20 target scope. We will see how it does before too long. And, as you said, brass is essentially unavailable as are dies in most places that have reasonable prices. Ammo is hard to come by as well.
At my age, probably never will shoot F-Class, but sure enjoy reading about it.
Thanks for your post!
