I would really like someone with a Ransom rest or similar to try some accuracy tests. I've made a couple I wouldn't mind really testing. There seems to be as much difference in coatings and accuracy as there is in different lubes. Just like I know there are harder lubes I wouldn't use in a .38 special of a softer alloy I'm thinking coatings have or are something similar but just different enough that it's taking some new thinking and testing. New mold designs may be needed as well. Think about all the efforts that went into solid copper projectiles. This isn't that different.
