GL49, I thought the same thing at one time. I have an entire quart of Hoppe's #9 sitting on the shelf because mineral spirits paint thinner cleans better in cast bullets and bullet lubes.
Some of these suggestions, you just have to try, then you'll understand. Hoppe's is great with jacketed bullets or factory loads. Then, add lead and lube to the powder residue, and I get tired of cleaning that much. The mineral spirits paint thinner, from the local lumber yard, is not only cheaper but, cuts it twice as fast. It amazed me, and it will amaze you also.
I thought it was about cheap, no sir, it's sometimes about better.
