I do not really know why, but lately I've been reading up on Desert Eagles as a potential range toy (no illusions as to its practicality for most situations). One thing I consistently read is that using cast bullets in it is a no-no. People go so far as to say using them will ruin the barrel, and you will have to send it back to MR to get them to clean the port since it is integral to the barrel. Reading all this, I couldn't help but wonder, couldn't one just use the dip (hydrogen peroxide and white vinegar) to clear it? I'm aware of the potential health hazards and would not want to do it regularly, but it seems a lot easier than sending it back to the factory. The suppressor crowd seems to have good results with the dip.
