No. 11 Cap and 209 Shotgun Primer
Caplocks traditionally use the No. 11 cap (above). Many current in-lines use a 209 shotgun primer (next slide); the hot ignition better fires the 150-grain powder charges. Some states, however, require percussion caps. Flintlocks use no primer at all, but a small amount of FFFFg powder in the pan. 866-286-7436; cci-ammunition.com. 800-243-9700; www.remington.com
