I'll probably get some negative comments on this, but my reason for doing it is the fact that I hunt mainly in wooded areas, and that long heavy45/75 28" BBL and full mag tube were just an annoyance to carry.
I made the plunge and cut down the barrel to carbine length - 19.5", and shortened the mag-tube to hold 4 rounds. I formed the end cap with J-B weld and rounded it off slightly. Turning the BBL to half round was a little labor intensive, as I do not have any type of metal lathe, but my 65 year old Shop Smith did suffice. I actually drilled out the base of a cartridge case and epoxy glued a steel dowel for inserting into the chamber and a drill chuck. I left the slightest amount of glue around the base, so it gripped pretty well when turning. Then it was just a angle grinder (with lots of cooling time), and then a good file and some sessions with various sandpaper. I didn't crown the muzzle, but it was reamed slightly and polished inside - we'll see if it needs crowning after I shoot it again. Re-blued with BlueWonder products.
I still need to mill in a front sight, but thought I'd get my story out there. I'll post up some progress pics later today - I need to find my camera and charge the battery I think.
Here are a couple of pics so far - I'm going to shorten the tube another 1/4" after looking at it closer....gotta get to work on that front sight now!
Well, I finished milling for the front sight, and the tube is done. Guess all that's left now is a shooting session
Anyhow - I think it will be a lot easier to carry next year, not to mention just plain plinking with it during the next 11 months......Here is the finished rifle....
