I'm thinking 30-30 and .45-70.
Also, the very best out there. that doesn't exclude those that tune an existing platform to make it better.
I know the BLR is the bees knees if you want something fast. I am considering their new take down as it's a sweet looking rifle.
I'm reducing my collection to a few finer arms rather than a lot of mediocrity.
IMO,...I would go for a Browning BLR model 81 chambered in .358win. The 81 has some-what of a traditional appearance and the 358 Winchester has some nostalgia to it, and is a very effective killer for any animals you will hunt in Canada. The only problem with the 358win is ammunition availability if you don't reload. A BLR 81 in 308 or 7mm-08 may be better for those who shoot factory ammo only. If you want the thump of a big bore the BLR 81 also comes chambered in 450 Marlin, but again 450 ammo is not too common.
You asked "what are the very best lever rifles",.. so IMO it is a short action BLR 81... weighs 6.8lb,...40" long,...detachable magazine,...action as smooth as butter,...and comes in a wide array of calibers.
I have a BLR Pistol Grip model in 358win, and a Model 81 in 284win and like them both very well, they are MOA accurate, and I have had zero issues with either,..I like the way the 81 handles a bit better than the PG.
,,,,.....well, there ya have it, my 2 cents worth,..lol.
