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 available from
Joe Hepsworth who manufactures them for Gibbs shooters.
This 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.
Thanks
to the Experts
Many shooters gave generously of their hard learned tips and recommendations
so as to make your Gibbs shoot better and sooner. Do your part by helping
others and sharing your own knowledge. Special thanks to Gibbs shooter
Joe Hepsworth, holder of NRA records for 800, 900, 1000 yards and the
Creedmoor record plus Steve Garbe, Dan Theodore, Blake Eckard, Heinz
