I had a Win 1890 relined by Redmond, was not a very successful experiment as it did not restore much in the way of accuracy. Further, was probably not a wise project on my part.
Imagine your grave on a windy winter night. You've been dead for 70 years. It's been 50 since a visitor last paused at your tombstone..... Now explain why you're in a pissy mood today.
As i said before the chamber is most important. The bullwt should have a short jump and there should not be a ridge left in the throat from the reamer.
