Fguffy please shed some light on where I can obtain the materials for a bech gun for so cheap. Heck I think two boxes of ammo would cost more than the barrels did.
As far as weighing cases goes I would probably weigh each case if I were depending on a caliber sized group at 500 yards to be able to cash a check to pay for everything, and eat. Though for the way I shoot, and what my rifles are used for I am happy with doing other things that give me under 1/2 inch groups at 100 yards. The flyers in my groups are a result of me.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
