Simple solution - have examples of several BPCR's! Tah-dah!
My first was a Marlin (wish I still had it), then an H&R carbine (sold and replaced with another), an H&R Officer Model, a Browning '86, 5 Shiloh rifles and carbines and one lone rolling block in .43 Spanish. And I'd like to add a few more to the list ..... Almost all are in 45-70, with a few .50's thrown into the mix.
Like Hambone sez - very addictive interest! But what's a hobby for? Anything worth doing is worth doing to excess. And he who dies with the most toys wins, n'est-ce pas?
I shoot them all occasionally, but spend most time with my Business Rifle and '86 of late. My interests come and go, depending on last movie watched, etc. I find that I can't take more than one to the range at any time and learn anything.
There is no interest locally in shooting BPCR's other than at our annual CAS event, but Gabriel law and I intend to change that with more offerings.
Like the Winchester '85 Highwall, the '86 seems to be the poor second cousin to the earlier Winchester stable of lever action rifles.
Probably John Browning's triumph of repeating manually operated rifles, but a little late on the scene to be deemed "Cowboy" enough to even warrant a column on this forum.
I've always wanted a Schuetzen-style rifle, but again, I'd be a majority of one around here and I'd have to add another calibre c/w dies, moulds, etc. in order to shoot it. Too many rifles, not enough time - or money!
