Good day guys....I am about to do pound cast on my CZ550 375 h&h. I have some .360 diameter molds....wondering if I put a 300 grain slug of pure lead down the barrel, would it fill out enough to complete the pound cast accurately? The lands look to be about .366 as best I can measure with calipers at the muzzle end of the barrel.
