Hoppe’s No. 9 Bench Rest Copper Solvent 16 oz Bore Cleaner

Description

When jacketed bullets travel down your barrel, copper gets left behind where the jacket meets the rifling. Let it build up and it starts changing how your rounds behave, which is the last thing a precision shooter wants. Hoppe's No. 9 Bench Rest Copper Solvent is a dedicated copper-buster built to strip that residue back down to bare steel. This is the pint-sized 16 oz bottle, and if you shoot jacketed rounds regularly, the larger size earns its keep.

This is a different animal than the classic No. 9 you probably grew up smelling. Regular Hoppe's is great at powder fouling and loose residue, but the Bench Rest formula is far more aggressive on the copper that plates onto your bore. It still carries that familiar Hoppe's scent, and it contains no abrasives, so you can clean thoroughly without scrubbing away at your barrel. Beyond copper, it also handles powder, lead, and plastic foulings across rifles, shotguns, pistols, and revolvers.

How Bench Rest 9 Earns Its Name

The whole reason this formula exists is speed and thoroughness. It was built for bench rest competitors and serious hunters who need a bore that's truly clean, and it lets you knock out copper fouling overnight rather than the three or four days some methods require. A common routine is running a few wet and dry patches, then leaving a well-soaked patch in the bore overnight and following up with clean patches the next day. Many folks like to sandwich it with regular No. 9 for a complete job.

Getting the Most From Your Cleaning

A couple of real-world pointers make a difference here. Skip the copper brush and stick with brass, nylon, or stainless so you're not confusing the solvent's readout on your patches. Since this is a copper solvent, always neutralize the bore with a light oil after cleaning and run a dry patch before you shoot. Work in a ventilated space and glove up, and you'll get years of reliable use out of a single pint.
