Hard to argue with the notion that the 98 is the greatest bolt rifle of all time. The combination of functionality, looks, history and panache is unapproachable by any other bolt gun out there.
But...why does the greatest sporting rifle need to be a bolt gun, or a repeater at all? It's taken a few decades, but I am the point where a bolt rifle is a tool...a tool that can admittedly be turned into a work of functional art, but a tool nonetheless; I worked with tools all my life, and I can appreciate them but I can only work up a limited amount of excitement for them.
Levers come much closer to satisfying me, but when I think of a sporting rifle the image that comes to mind is a lithe, graceful and accurate single shot.
Any hunt is a terrific experience, but if I am planning on something that is extra-special...or if I want a "normal" hunt to become special...I want to use a single shot rifle, preferably a falling-block, ideally iron-sighted. Sadly, with age the iron sights become less and less useable, so a scope is acceptable; but I still want the pure experience of opening an action, inserting a single cartridge, closing the rifle, aiming and firing one shot. And I want the rifle to be beautiful; when sitting in a deerstand or taking a break for lunch, I want to look at it and think to myself "That's nice..."
I have a C.Sharps .45-70 which is a treasure, but again, the sights are becoming less manageable for me, and it may have shot its last warm target. A graceful little Haenel Jaeger model 9 in 7x65R comes close; lets me use a scope, weighs nothing, handles like a dream, shoots beautifully...but it is a break action and that nags at me just a tiny bit. I've also owned a ton of H&R/NEF singles over the years and loved most of them, but they are clunky and unrefined and of course they also break to open. T/C Encores and Contenders feel like 2x4's to me, very poor handling. Martinis are nice to shoot, but about the ugliest things on the planet. Winchester 1885's? Close...very close, but...
Historically, the Farquharson single shots seem to come as close as possible to my ideal...but I have never even held one, much less fired or used one. So, in case it hasn't become obvious already, the gun I am circling around as my own favourite sporting rifle model is the Ruger #1. Even when chambered in rimless cartridges they seem to be stone-axe reliable, usually shoot very well and they check all the other boxes of my own imaginary list perfectly. I think they are the most beautiful regular-production guns out there, they are still readily available both new and used, and by today's insane standards they are still reasonably priced.
Yep, a Ruger #1S, with a 26-inch barrel and the Henry-style fore-end, wearing some nice walnut, trigger properly adjusted, safety slide either upgraded or at least shaved to prevent snagging of empties...the perfect sporting rifle for this old codger. Just my opinion, of course, and worth every penny you paid for it.
