I thought we were talking about a hypothetical rifle?It's much easier to find bolt guns that'll shoot .350 Legend than .357 Max. Are there any .357 Mag bolt guns with a magazine that can handle the length of the Max cartridge? Single shot rifles in .357 Mag make a lot of sense to rechamber to a Max with it being a rimmed cartridge. I can't imagine the cost involved in converting a bolt action rifle that'll function and feed .357 Max from a magazine reliably. While in comparison you can buy bolt rifles already chambered in .350 Legend or convert any .223 bolt face rifle for the cost of a barrel and installation.
There have been a lot of bolt actions chambered for rimmed cartridges. 303 British, 30-30, 22 Hornet, 225 Winchester……. Should be able to make a dream gun work with the Max. I load 35 Remington bullets in my Contender, no shortage and matched almost perfectly for the velocity generated by the Max.
