Yes, Mike Venturino's book
Shooting Lever Guns of the Old West is a good source.

The 1886 action is amply strong for smokeless powder but if it is not a nickel steel barrel, I would stick to cast bullets at moderate velocity for any amount of shooting. A 260 gr lead bullet at 1200-1400 fps will do anything necessary to a target... or a deer.
A box or two of jacketed just to say you had shot the gun will not hurt it. Jacketed bullets were available in the late years of the caliber's production.
