Paradox guns are wonderful intruments. Not only can they be used to shoot birdshot
with aplomb but they also serve aptly as large bore double rifles. Paradox owners are quick to grasp the utility
of their guns but often only discover the full potential of a Paradox gun through trial and error. Collected here
are a few bits of information that may assist owners of Paradox guns in their pursit of the quintessential Paradox - a shotgun
that is a rifle that is a shotgun.
SHOOTING PARADOX CARTRIDGES
There were many developments in
Paradox guns and ammunition over many years. A good expalanation of the various "standard" 12-bore Nitro Paradox ammunition
can be found in Chapter 15 of David Baker and Roger Lake's excellent book, 'Paradox - The Story of Col. G.V. Fosbery, Holland &
Holland, and the Paradox'. Suffice to say that not all Paradox guns were made to shoot and regulate the same load. This
leaves Paradox owners two choices. They can either load their own cartridges, tailored to their specific gun, or they can try
and shoot the current "standard" Nitro Paradox ammunition, adjusting sights or, if required, have the gun re-regulated.
who enjoy "rolling their own" ammunition, no better reference can be found than the final chapter of Graeme Wright's 'Shooting the
British Double Rifle'. The author goes to great lengths to explain the process of casting and loading Nitro Paradox ammunition
using various materials and methods. He also explains how shooters can adjust the loads to get them to regulate, or shoot to
the point of aim, in a specific Nitro Paradox gun. Regulating a gun by altering the ammunition can be a tedious
process but, once accomplished, can breath new life into an old gun. We strongly recommend Graeme Wright's book to anyone
interested in loading for and shooting the Paradox gun.
Factory ammunition is the other option. Owners of new Paradox
guns will be pleased to know that their guns were regulated for the new ammunition at the Holland & Holland factory. Before
shooting second hand guns, it is recommended that owners contact Holland & Holland, London to learn more about their
gun and it's suitability for the modern Nitro Paradox ammunition. Most owners of older Nitro Paradox guns will find that
the factory ammunition groups well in their guns and that little or no change to the gun is required to get their
gun shooting to point of aim. The most common adjustment needed is installation of a taller front sight bead. There
will however be a few guns in which the new ammunition will not shoot acceptably. Owners of these guns should either
have them re-regulated for the new factory ammunition or, as explained above, work up some custom loads. There are a few companies
advertising that if you send them a gun they will work up special custom loads and keep the data on hand to so as to make more
as required. It is worth noting, however, that we have heard reports of varied success in that regard.
IN PARADOX GUNS
It is a general rule that the higher the velocity of a shotgun cartridge the greater the dispersion of the
shot, i.e. a bigger and more uneven pattern. So it should come as no surprise that low velocity shotgun ammunition
tends to pattern better than high velocity ammunition in Paradox guns. In fact, the difference in patterning between
low and high velocity ammunition seems even more apparent in the Paradox gun, perhaps being related to the rifled chokes of Paradox
barrels. Nevertheless, lower velocity shotgun loads seem to be one option for getting better patterns from these
Some shooters may feel that the suggestion of low velocity ammunition for their Paradox gun presents them with
a dilemma. Should they shoot a low velocity load that patterns well but is limited in range or should they shoot a very
fast load for better downrange energy regardless of how it patterns? Luckily, there are factors other than muzzle velocity that influence
downrange energy of a load. Probably the most important is the shape and hardness of the shot. Rounder and smoother pellets
create less drag in flight than shot that is dimpled and/or misshapen. Pellets with less drag retain velocity better
and, therefore, more energy is delivery to the target. The single biggest cause of dimpled and misshapen shot is the
pellet to pellet beating that occurs in the chamber, barrel, and choke once the load is fired. Shot with
higher antimony content is harder and pellet deformation is reduced. But because antimony is more costly than lead,
the best pellets are only found in "premium" game and target loads. Of course, since firing pellets does
not improve roundness it is also very important to start off with pellets that are of properly rounded form to begin with which.
And again, the best formed shot is found in premium loads. A benefit of using premium grade hard, round pellets is that they
also result in better, more consistent patterns. So, another option for getting better patterns with a Paradox gun is to shoot
moderately fast "premium" loads made with hard, properly formed shot. The hard shot deforms less passing though the gun
and the rounder pellets that exit the muzzle will retain their velocity better and perform better on targets at
Shotgun cartridges loaded with felt or fiber wads also tend to do better in Paradox guns. It
has been speculated that a plastic shot cup unduly disrupts the shot column as it passes through the rifled choke of the Paradox gun.
A felt or fiber wad travels behind the shot and does not interfere with the shot column as it passes through the Paradox choke.
An added benefit to shooting with fibre wads is that they tend to swab out the barrels as they move behind the shot.
That result is a stark contrast to the residue that plastic wad cups can leave behind in the bores.
What shotgun cartridges do
less well in Paradox guns? The answer is threefold. Firstly, cartridges that contain heavy loads of
soft shot, especially when the load is pushed to high velocity. Secondly, very high velocity or magnum loads - even if
they contain hard shot. Perhaps this is because the benefit of hard shot is offset by the general tendency of very fast loads
to pattern less evenly. Thirdly, cartridges that use plastic, cup type wads tend not to pattern very well in Paradox guns.
support of those principles, we have found that our 15/16 ounce Light Load (soft but light and less fast) and our 1
ounce 'Royal' Game load (fast but hard and light) give excellent performance in all the Paradox guns we have tried
