Came into a 357 mag rifle with a .355 bore which begs the question of does one try a 9mm (.355) jacketed bullet or a .357 diameter jacketed bullet. Concerns about using the .357 diameter in a .355 bore include a potential loss in accuracy from the mismatch or an increase in pressure. Advantages of using the .357 selection of jacketed are the wider variety of jacketed bullets available. Mostly this will be a cast boolit rifle, but wondering about the potential constraints presented by the .355 bore.
Thanks in advance
