My security six is my favorite revolver and I shoot it a lot. Since taking up casting, I have had issues with leading in even low power 38 loads that isn't related to lube or alloy. As an example, my standard dewc target load is very accurate in the gun for the first 50 shots, then degrades and I have a leaded barrel to clean. Suspicious, I took a bullet and tried to shove it through the cylinders. No go. In fact, what I decided to try as hard as I dared it got stuck badly enough that it required a punch and mallet to back the bullet out. In contrast, the snub which has never leaded at all only required modest pressure to get a 358 sized dewc through the cylinders.
I think what is happening with the security six is the tight throat swages the bullet too small for the barrel. It the skids until the pressure obturates the soft alloy. I get good accuracy anyway until the leading gets too bad and the initial skidding is why the leading is mostly in the first inch or two of the barrel.
I think the solution is throat reaming, which I am unwilling to attempt myself. How do I make sure this is the solution? Would a good.Smith be able to confirm and figure out how much the cylinders need to be reamed before doing it? Anything else I have not thought of?
