I have a new CMMG Banshee in 45 ACP. I tried some of my normal loads for it (been shooting in my 1911's for years) and it leaded the barrel. They are sized at .452. I slugged the barrel and found it to be .452 I tried casting a few 200 grain bullets and sized them to .453 and they shoot just fine with no loading.
Question is I have a bunch of 230 grain bullets I casted and coated then sized to .452 Can I put another coat of powder coat on them and then size them to .453? Will the powder coat handle the head and pressure and not let the hot gasses leak and then cause leading? I could just recast them and I will if I have to but I am lazy.
