The .358 is an excellent cartridge, in addition to .35 caliber rifle bullets you can shoot a broad range of other bullets. These include .35 cast bullets, .357 pistol bullets both cast and jacketed. That is a big part of the .358's appeal for me, I have owned pre '64 Winchester M/70 Featherweight and M/88 lever actions chambered in .358. Currently I am shooting two .35 Whelen's based on pre '64 M/70's. I would recommend reboring as the most practical option, I have used Randall Redman to rebore and rechamber one of my Whelen's. I can recommend his work without reservation.
