How much weight can you cut in shortening a barrel like this?
Figure it out. Assume a cylinder that's the diameter of the muzzle, with a cylindrical hole through it the diameter of the bore. Figure
pi (3.1415927) times r� (the radius � the radius) times the length of the cut-off stub for the volumes of the stub and the hole in cubic inches. Steel weighs about 0.283 to 0.284 pound per cubic inch.
Somewhere around this midden that I live in, I have a two-inch stub off the muzzle of (IIRC) a .257 barrel. I weighed it many years ago � no more than a couple of ounces, as well as I can recall. Certainly not much.
