Tipton Best Nylon Bore Brush 270/7mm 3-Pack

Sized for 270 Win and the 7mm bores, including 7mm Rem Mag and 280 Rem. Magnum cases push a lot of powder past the throat, and this brush has the stiffness to clear that residue in fewer strokes.

Nylon takes ammonia based copper removers without corroding, so the brush stays in service through repeated soaks. Extra thick bristles hold their shape instead of collapsing, and the brass build keeps the bore free of scratches. Three brushes total.
