Large bore diameter for my 32-40? (Read 3224 times)

	Something is not right. The ASSRA Ruger NO. 1 has a #3 8-groove barrel with no cartridge designation. I was told it was 32-40. The pound cast mic'd out at .3272 for the throat and the bore .3245-.3263. Is this unusual?

	I always make chamber casts of my rifles, and some of my pistols. Make a Cerosafe chamber cast; then you will know. These are two chamber casts; the top one is a 30 luger chamber, the bottom one is a 32-40 with a .330 groove diameter.

	What is a "pound cast" ? Joe.

	Seat a pure lead bullet into a lead filled case, chamber. Insert a brass rod down the muzzle and tap it until it bounces. Tap the result out lightly and one has a good cast of the throat and leade. No substitute for a chamber cast however. westerner wrote on Feb 20^th, 2015 at 10:17pm: What is a "pound cast" ? Joe.

	Okay. Have done it many times myself. Usually tells me everything I need to know. Large diameter .32s are out there. Not common, but they're out there. Joe.
