What thread size does the Pro-Shot J375B jag use, and will it fit my existing cleaning rod?

The Pro-Shot J375B features a standard American #8-32 male thread interface. It is designed to pair directly with cleaning rods featuring a female #8-32 thread, such as Pro-Shot rods for .27 calibre and up, or Dewey rods equipped with a #8-32 female adapter. It will not fit smaller .17/.20 calibre rods or standard shotgun threads without a thread adapter.

Can I use ammonia-based copper solvents with this solid brass jag during outback cleaning sessions?

While the precision CNC-machined solid brass is completely safe for your barrel steel and won't scratch rifling, you should avoid using aggressive ammonia-based copper solvents with it. Ammonia reacts chemically with brass and can produce false-blue staining on your cleaning patches, making it difficult to accurately gauge copper fouling removal from your .375 bore.

What prevents the cleaning patch from bunching up or jamming inside a .375 H&H or .375 CheyTac bore?

The jag features a sharp central spear-point design that pierces the exact center of the cotton cleaning patch. This anchors the patch securely and distributes it evenly across 360 degrees of the bore diameter, acting like a precision squeegee to strip fouling smoothly without jamming.

.375 Caliber Jag - Pro-Shot J375B

The Pro-Shot Spear Pointed Benchrest Jag (.375 Cal) is a precision CNC-machined firearm maintenance accessory designed to clean .375-calibre rifle barrels. Constructed from solid brass, this unpowered cleaning jag safely guides solvent-soaked or dry cotton patches through the bore to remove carbon, powder residue, and fouling. The softer brass composition eliminates the risk of scratching the chamber, rifling lands, or bore crown during routine maintenance, while the base features stamped calibre markings for fast identification on the bench.

Key Features

Spear-Point Design: Centrally pierces cotton cleaning patches to keep them firmly positioned, preventing patch bunching, slippage, or bore jamming during the cleaning stroke.
Benchrest Tolerances: Precision-sized exterior diameter ensures 360-degree contact between the draped patch and the bore wall, acting as a squeegee to strip residues efficiently.
Barrel-Safe Brass Construction: Machined from solid brass that is softer than barrel steel, safeguarding delicate internal rifling surfaces and the barrel crown from tool damage.
Standard Thread Fitment: Integrates an industry-standard #8-32 male thread interface compatible with standard rifle cleaning rods.

Who is the Proshot Spear Pointed Benchrest Jag 375 Cal for?

Big Game Hunters — maintains large-bore safari hunting rifles chambered in .375 H&H Magnum or .375 Ruger using a spear pointed cleaning jag precision-sized specifically for .375-calibre bores.
Extreme Long-Range Precision Shooters — strips powder fouling and bore residues evenly from .375 CheyTac platforms with a spear pointed cleaning jag equipped with a standard #8-32 male thread interface.

Less suitable for: Barrels with internal bore diameters smaller than .375 calibre where the oversized jag will cause cleaning patches to jam, cleaning rods with smaller #5-40 or larger 5/16-27 female threads, or applications involving aggressive ammonia-based copper solvents that chemically react with brass; these scenarios require smaller-calibre jags, appropriate thread adapters, or nickel-plated, non-brass proof-positive cleaning jags.
