I've been making round balls for 40 plus years . But, recently I accquired a new demand for them. I've gotten an air rifle . A 50 caliber air rifle. I'm not happy with the as cast balls I have been shooting. My mold is Lee , at .495. I would like to go up to about a .498. My question is , do you think my wanting to open a .495 mold by the weet method will work? I don't mind loosing a mold if I screw up but, I know there are those here that could predict my chances, and I really respect that . Thanks ahead for any and all comments. Thank you Chuck.
