So, I have access to a takeoff 270 barrel for minimal cost. I own a 7x57 reamer. I am thinking of making a Handi stub barrel in 7x57 rimmed.
The 7mm calls for a .284-5 bullet.
The 270 calls for a .277.
Another thought is that I could use a cut down 270 size die, neck size, and load with the smaller bullet and call it a 270 Rigby.
One thought on the different nomenclature is that it would likely never be shot/blown up after I leave this earth as nobody would have the correct cartridges for it. I am making it rimmed, so a normal 7x57 would not chamber.
What are your thoughts?
