I'm new here, and have a question. Is the square bolt on a Marlin 36R in 30-30 interchangeable with the square bolt on a Marlin 36D in .32 Winchester Special?
As far as the rounds, the rim sizes are same same but dont bet on any interchangeability, even if they are same same otherwise mechanically, due to the hand fitting found in older weapons. I would imagine they could be made to fit though, given headspace issues do not appear, which is very likely as well.
Two things that have never and will never be successful... the "war" on poverty, and gun control laws.
