Percussion Caps

There are several brands of percussion caps available and they too differ in performance. The Gibbs delivers good accuracy with RWS brand #11 caps. Remington, Dynamit Nobel and CCI also make #11 percussion caps which can be tried out.

Types of Nipples

The standard nipple on the Gibbs #USA 484-3 (3 pack) is made from Beryllium and is available from Pedersoli dealers. A lower priced steel nipple is available as part # USA 470-3 (3 pack). The Beryllium nipple lasts much longer and resists fouling and corrosion better. Standard steel nipples should be replaced after every 40 shots have been fired in order to maintain accuracy. A special platinum lined nipple is recommended for serious match shooting because it resists fouling better and has a very long life. Due to the heat and corrosive gasses, nipple threads can become stuck and resist removal. It is always recommended to use Teflon plumbers tape or some anti-seize liquid on the nipple threads when installing any type of nipple.

Shooting the Gibbs

Each shooter will develop their own holding and sighting technique according to type of rules and course of fire involved. Most (but not all) of the top shooters suggest holding the stock very firmly in the wrist and forearm. We suggest you try this type of firm holding before settling on some other type of hold. To get you started on sight elevation settings we offer the following settings which work for the 540 gr. Higginbottom-Rigby bullet as well as for the 535 gr. Pedersoli bullets. Muzzle velocity is 1300-1325 fps using 100 gr. of Swiss 1½ powder. If your load chronographs at similar speeds these elevation figures should be very close to right for you.

100 yards minus 13 minutes on elevation scale.
200 yards zero (0′)
300 yards up 12′
500 yards up 44′
600 yards up 59′
800 yards up 95′
900 yards up 112′
1000 yards up 130′

Your sight may be marked differently so just use the minutes variations from your 200 yard setting and make your own sight setting chart after you see what your rifle and load does at each distance.
