This project is still in the "thinking about it" stage, but... yesterday a lady came in and sold the store I work for an old Colt Bisley revolver in .38 Long Colt. From what I can tell so far, it has the typical oversized bore of around .375" - .380" that was designed for the old heeled bullets of the .38 Short Colt. This weekend I will slug the bore and get the exact bore diameter.
Now, I understand that I could simply shoot .358" hollow-based wadcutters and hope they expand in the cylinder as was done in days of yore. I could also get some .375 heeled bullets and go that route.
Did I mention that I will be buying the revolver no matter what?
An alternative occurred to me that I thought might be feasible. Suppose I was able to obtain an extra cylinder which could have its chambers reamed out a bit, say to .380 or so. I could then potentially fire-form some .38 Special or .38 S&W brass, load 'em up with .375 diameter bullets and head out to slay some empty milk jugs.
I was thinking of Trail Boss or Triple Seven loads of about 700 FPS with a 225 - 250 grain bullet.
Any reason that this could not work?
