Hop #9 Plus Blk Powder Solvent 8Oz (10)

Black powder shooting demands a solvent built specifically for the job—and Hoppe's No. 9 Plus Black Powder Solvent is exactly that. This 8 oz bottle (sold in a 10-pack) is engineered to cut through the heavy fouling that black powder leaves behind, dissolving residue while simultaneously lubricating your bore as it works. Unlike all-purpose gun solvents, this formula tackles the unique cleaning challenges of black powder rifles, pistols, and muskets with a two-in-one approach that saves you time between shots and at the range bench.

Black powder shooting, whether you're competing in matches, hunting with traditional arms, or collecting historical firearms, requires regular, thorough cleaning to maintain accuracy and prevent rust. Hoppe's No. 9 Plus works in both deep-grooved and shallow-grooved barrels, making it versatile across everything from modern in-line rifles to classic percussion and flintlock designs. The lubricating action helps protect against corrosion during and after use—critical for keeping your bore in top condition when you're shooting corrosive black powder or substitutes.

The 10-pack format makes sense for serious black powder enthusiasts: stock a bottle in your cleaning kit, keep one at the range, and have extras on hand so you're never caught without the right solvent. Hoppe's reputation for reliability in the field and on the bench has made No. 9 a standard among hunters and shooters for generations, and the black powder formula carries that same trust.

Frequently Asked Questions

Can I use this on all black powder firearms?

Yes. Hoppe's No. 9 Plus is formulated for black powder rifles, pistols, and other firearms that shoot black powder or black powder substitutes. It's effective in barrels with both deep and shallow rifling patterns, so it works across traditional muzzleloaders, modern in-line designs, and historical arms.

Does this solvent protect against rust between uses?

The formula includes corrosion protection, helping safeguard your bore against rust when applied during and after cleaning. However, your overall rust prevention depends on storage conditions and regular maintenance.

Why does a 10-pack make sense for black powder shooters?

Black powder shooting typically requires more frequent cleaning than centerfire rifle shooting because of the heavier fouling. Having multiple bottles lets you maintain one in your shooting kit, keep a backup at the range, and stock extras for field use or long shooting sessions without running out.

What's the advantage of this product compared to general-purpose gun solvents?

General-purpose solvents aren't optimized for black powder's unique residue, which is more stubborn and corrosive. Hoppe's No. 9 Plus is specifically formulated to dissolve black powder fouling while lubricating your bore, combining two jobs in one product—faster cleaning and better protection for your firearms.
