Tipton Best Nylon Bore Brush 50 Cal 3-Pack

The 50 caliber size handles 50 BMG, 50 Beowulf, 500 S&W, and 50 caliber muzzleloaders. Big bores hold a lot of fouling, and a full diameter nylon brush with thick filament moves it in fewer strokes than a worn out bronze brush.

Nylon shrugs off the copper solvents that eat bronze bristles, and the brass core will not touch the lands hard enough to matter. Three brushes come in the pack, which counts on a bore that goes through them.
