Since neither you or your friend want to shoot it I think the best thing is to sell it as salvage -
Still quite a bit of money in the brass, bullets, primers and even the powder ( if it can be identified).
Shooting another persons reloads is not good policy, things can go wrong even with your own.
Selling them as ammo could create an unwanted liability to the seller if something goes wrong -
A modern 45-70 load shot in a trapdoor for example --
Sell the lot "as is" as salvage and at salvage prices -- buyer can then make a decision to break the ammo down or shoot it --
