I have a weird phobia about pushing cartridges into a loading gate, some aren't too bad but the ones where you really have to crunch them in there are a problem for me.
Ahem...the slickest lever action ever, in the history of the world, is Browning's BLR.
Next thing you know, Ardent will be hunting with a lever 45-70. Great round
I find the curved lever and grip of a Winchester Model 71 is a big improvement over the 1886 for smooth cycling. I think a M71 is the slickest lever action ever. I have one with a four digit serial number which is particularly slick, likely from the years of use, but my Browning carbine and recent Miroku are great also. I love the Model 71 and wish the 348 cartridge was more available and affordable.
I’m surprised nobody mentioned the Colt/Sauer rifles, they were known to have super smooth actions. I handled one at a gun show recently and they are indeed ultra smooth.
Maybe I missed it, but what do you plan on using your custom 10mm lever action for?
Likely one or two small coastal deer for kids, but mostly the targets and smiles. And even more than that to just to satisfy a gun nut’s itch.
Winchester 71 is the best. 348 Winchester is a very cool round can be loaded 150gr to 250 gr jacketed bullets and up to 300gr cast bullet. Interesting article years ago with guy cycling his 71 upside down with ease, good to know in case a grizzly chases you up a tree and you are hanging off a limb.
The Savage99R (and RS )is said to have the second best stock design for snap shooting a lever gun after the Winchester 71.I have Rs in 308 and 300Savage and have found they are really handy.
The Finnwolf is the most accurate of the lot, slick as snot and magazine fed. BUT the mechanics of the action strikes me as delicate,they are rare and valuable. I have hunted with my 71's and my Savage99s. I would never hunt with my Finnwolf, except maybe if I were in my buddy's heated blind , a small travel trailer on tall steel poles
Bottom line. Find yourself a Winchester 71, best of class.
I’ve been on the hunt for a couple years for the right .25-20 takedown, or a Model 65 .218. I suspect I’d have a lot of fun with a miniature 1886.
