to be honest, i will cringe the first time i have to use a bore brush. Just doesn't seem like it should be used. Just my silly opinion. That's why i clean my guns after every time out.. hoping to avoid running a brush down the barrel. I will look for CR-10 and/or sweets. I didn't see it on the shelf today. I did see a new product by Hoppe (with a gold label). the gun smith said he heard very good reviews with that product too.
