I like it so well I store or got rid of the old plunger type rifles in which its not supposed to be used. Since I switched to BH I clean my guns at the range I use a 50 /50 mix of alcohol and Hoppes #9 its works quite well and it takes 6 or 7 minutes per gun I normally shoot more than one as I live in AR and the temperature here is often over a hundred which requires quite a bit of cooling time.
The only thing I considered a problem I fixed with a mod to the BP. If you use the standard BP then you need to keep a drill handy to get the carbon out of the BP flame channel between the primer seat and the touch hole every 10 or 12 shots and even with the flame channel opened up with a #21 drill and a Lehigh vent liner installed I have to clean it out with a drill when I clean the gun after shooting.
