Sellier & Bellot 10mm Auto ammunition (brand part no. SB10B) loads a 180-grain jacketed hollow point bullet in a brass case, giving 10mm shooters an expanding defensive load without the premium price of a boutique hunting line. The hollow cavity fills with tissue on impact, driving the jacket petals outward for a wider wound channel and reliable energy transfer, while 10mm’s inherent power keeps velocity high even in a mid-weight 180-grain bullet. That combination of expansion and raw cartridge energy is exactly why 10mm has built a following among both concealed carriers and backcountry hikers who want defense against large predators. For 10mm shooters who want dependable expansion at an accessible price, this handgun ammunition from Sellier & Bellot is built for exactly that.
