Dayrl is correct I was referring to imperial die sizing wax. Stuff works great and a little goes a long way to eliminate the dreded lube dents. Haven't tried the 375/30-30 cases yet. Looking for a 180 grain cast bullet that will cast fat enough to match the internal dimensions on the barrel of the canadian cennentennial comemorative carbine made in 1966. Savage used to make a 190 grain jacketed round nosed bullet in their 303 savage ammunition. sadly it has gone the way of the dodo. I suppose I could take some 30 caliber 180 grain round nosed bullets and try them first.As far as velocity is concerned you all know you can get a few extra feet per second using cast bullets. So that is where that project stands for now. One amongst many. Frank
