I have a bunch of single shots personally, mostly Rugers, but a Shiloh as well, original 1885, and others. Even a Holland & Holland Field's Patent, which is a lovely thing.
One thing I've noticed over the past 10-15 years is many components, like brass, are increasingly difficult to obtain for some of the more esoteric cartridges. Jamison I guess went under a few years ago, which was a good source.
I wouldn't mind acquiring another BPCR, in a lighter rifle and cartridge, better suited to deer & pigs, but many of those cartridges are not easy to source for components.
