45-70 in a Ruger number one.....420 grain super wide meplat. Cast her up with a high temp gun,...never thought about lubing it. Loaded the case with a magnum rifle primer and pushed the round into place. Had the common sense to stand behind a wing chair in my man cave to protect the family jewels in case of a ricochet . very heavy waxed cardboard box, with the local phone book about a 1.5" thick inside. Placed in on the other wing chair at the end of the room about 12-15 feet away and let her rip.....cleaned the box, phone book ,out the back of the box and a nice hole in the fabric of the other wing chair. Got the " you're and idiot " look from the better half. Be careful folks these could easily kill at close range. They're a hoot to shoot, but I had better come up with a better backstop, or I'll be sleeping outside with the dog.
