Hope some one can answer this.
I am interested in rechambering a 40-65 to 40-82.
According to listed dimensions, there is a small section at the bottleneck shoulder where the 40-65 is larger than the 40-82.
Has anyone rechambered without setting the barrel back?
If so, any problems?
Any comments?
Thanks in advance.
OS.
