Remington #10 Percussion Caps are fabricated from a non-corrosive, non-mercuric compound mix and assembled in individual, ribbed, copper caps for use in black powder revolvers having smaller nipples. These ribbed caps match standard #10 nipple sizes and provide both clean burning and extremely reliable ignition.These percussion caps are continuously being tested and improved. As a result, today's Percussion Caps are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. Remington #10 Percussion Caps are packed in traditional 100 count tins and can be ordered in 100 count.
