Milton You can pour a chamber cast using parafine. I do it all the time. Just lightly grease the chamber and make sure you get it full all the way. As it cools you will have to add parafine. The trick is to let it cool and harden for a hour or so and then nock it out and throw it in the freezer for about an hour. That will let you handle it for long enough to get your measurements. By the way try not to pour it on the outside of the barrels. Makes a real mess. Take a set of calipers and set them at .835. Slide the cast into the calipers until they just touch the parifine. Slightly rotate the cast to make a light mark. Then you can measure the lenth.
