So it comes so close to the 12 ozs of the 8" aluminum can that there's no detectable difference in handling, at all. They want $1000 a for a Top of the line can for the 223, plus Big Brother's $200. Devoting a day to making one, and losing $300 on the buy and sell prices of a little lathe and a torch still leave you making well over $75 an hour. HOw many CLEAR that much, after taxes, etc. ? Not many. Of course, how many understand the lathe and the torch well enough to be able to make a good can for a 223? Even fewer than clear $75 an hour.
