hey Brent ... I have a new production Sharps Borchardt action that I would like to chamber is .40-50 Sharps Straight -or- 40-70 Sharps Straight
... and here is where I get confused and cautious ...I looked at bore and groove diamteres of modern blanks and I am betting that modern groove diameters offered by Douglas (0.400 / 0.410) or Krieger (0.400 / 0.409) are bigger than original. I saw case brass, forming and reloading dies listed at MidwayUSA in both 403 and 408.
I am sure there is a reason or all of this but not sure what that reason is ... yet. Any help straightening this out is appreciated.
... Joe
