I bought the tipton 30 cal nylon bore brush tips to clean my 308 precision rifles. They do the job well and prevent scratches to your rifling. However, when used with hopes solvent, the nylon tends to wear out much faster than copper brushes. Make sure to buy plenty if you shoot often.
Pros: Works well, prevents damage to bore
Cons: wears out fast when used with hoppes bore cleaner
