It feels like an eternity has passed since I brought back my first
batch of Hevi shot from the states, a loose bag of shot that cost a
fortune. I thought I was a mug having just paid over $10 a lb for
stuff that looked like slag; misshapen with small attached nodules
and hardly a uniform sized pellet to be seen. My instinct was this
was going to fly and pattern, well, like shit. How wrong I was.
For 4 seasons now I have loaded this shot loose into my 10, driven
on by its effectiveness for it is absolutely stunning when used on
geese. I remember the long drive to Birmingham proof house with the
first ten loads, all the way I was convinced that they where going
to break the barrels with excessive pressure, instead they sailed
through at 1300fps and 890bar for a 2oz load. I remember when I
first patterned tested them and looked, in awe, at the pock marked
half inch steel pattern plate, then immediately look down by guns
barrels fearing the worse; the barrels where as smooth as a
politicians tongue. But, alas, thought it was excellent and a new
non-toxic material available, it was only available to the
homeloader.
Times have marched forever onward and at last Hevishot is available
in the UK in the form of commercial cartridges. Well how do they
perform, do they live up to expectations?
But first let’s step back –Let’s reflect on what Hevi Shot is?
Hevi-shot is a dull metallic grey compound metal. It’s a combination
of Tungsten, Nickel, and Iron, amalgamated in approximately a 50%,
35% and 15% mix respectively. Hevi-shot has an average density of
12.0g/cc (grams per centimetre cubed), which is greater than the
11.4g/cc for pure lead, 10.9g/cc for the high antimony premium
hunting lead shot and approximately 7.8g/cc for steel shot. This
makes Hevi-shot approximately 10% heavier than hunting lead and 52%
heavier than steel when compared with a similarly sized
premium lead or steel shot pellet.
In sizing Hevi-shot is must be said that a uniform pellet may be
hard to find, for in this respect Hevi-shot is definitely an
oddball. Hevi-shot pellets where anything but uniformly spherical;
to be honest they tend to be all shapes of oval with or without
attached smaller nodules. On initial viewing this un-uniformity is a
source of ridicule, however this ridicule is short-lived once the
ballistics results are viewed.
Hevi Shot is hard, bloody hard if you excuse the French. This
hardness of Hevi Shot is the reason why EnvironMetal, the
manufacturers, do not recommend its use in shotguns that are not
designed for Steel Shot, and for those that are, it is recommended
that you do not use any chokes not designed for steel shot with
modified being the maximum recommended restriction. You won’t need
more anyway. For home loaders another important consideration is
that the shot must be enclosed in a special wad. This special wad is
to ensure that whilst the shot is making its way up the barrel it
does not come in contact with the barrel else wise barrel damage may
occur.
Advantages
Hevi-shot’s pattern is tight, very tight, even when passed through
an improved cylinder choke. This increase patterned density enables
a 12 bore cartridge containing a load of 36g to be used effectively
at 40+ yards against the smaller species of waterfowl. This 40ish
yard range is the debateable limit of use of steel shot, as beyond
this the pattern has a greater tendency to “flare” hence producing
large gaps within the pattern.
So, to the result from patterning the Lyalvale cartridges.
The Test
Each test was shot through a Semi-Auto Benelli Super Black Eagle (SBE)
which has a 28 " barrel, 0.724" ID bore ( classically under bored).
The Gun has a 3.5" chamber. The sole choke used was a Briley X2 in
Light modified (3/8) which is of a conical profile.
The weather details are, Wind 0mph, Temp 15’C, Pressure at Doveridge
= 1017mB
The loads tested were
A) Lyalvale Hevishot 2.75" No 5 ( measured at 3mm average *) 36
grams ( taking 3 apart confirmed that they where 36 grams and had an
average of 210 pellets ) . Measure muzzle at 2.5 (average of 10)
1305fps SD 23
b) Lyalvale Hevishot 3" No 4 ( measured at 3.3mm average *) 40 grams
( taking 3 apart confirmed that they where 40 grams and had an
average of 175 pellets ) Measure muzzle at 2.5 (average of 10)
1238fps SD 26
( *measure the median size pellets, it was like quality street they
come in all shapes and sizes)
A synopsis of the results are in the 30" circle ( average of 10)
30 yards, Cart A -- 208 (98%) SD 7 , Cart B --161 (92%) Standard
deviation 7
40 yards, Cart A -- 185 (87%) SD 11 , Cart B --156 (88%) Standard
deviation 6
50 yards, Cart A -- 136 ( 64 %) SD 10 , Cart B -- 96 ( 54 %)
Standard deviation 5
60 yards, Cart A -- 75 ( 35 %) SD 4 , Cart B -- 80 ( 45 %) Standard
deviation 4

Comments
I would class these as two different loads for two different quarry
my own requirements for a clean kill of a goose and large duck load
are 80 and 120 appropriately penetrating pellets in a 30” diameter
circle, respectively, and at the range I intend to shoot.
Load A) the 2 ¾ load, achieves the figures for duck and geese to 50
yards, however when working out the energy density, it is debateable
if this pellet size has the energy to bring down a goose at 50
yards, it is on the edge, and I mean right on it.
Load B) the 3” load, because of its pellet size it will quite
happily demise a goose at 50 yards, but the pattern at 50 is a bit
light for a large duck, and at 60 is again on the edge, the very
edge, for geese.
Hence, in my humble opinion, Load A and B will perform on Geese and
Duck to 40 yards, but divide into a goose ( 3 inch cartridge larger
pellet) and a duck ( 2 ¾ inch cartridge smaller pellet) load after
40 yards. This is not surprising really, as I am sure that this was
Lyalvale’s intention. At 30 yards both will shred the quarry and you
will have to be “on form” to hit the bird.
In summary
So what is Hevi-shots future in the UK? Even at the current RRP I
reckon it will sell, but it will only be used in sparing quantities
for the red-letter days or a swatter load to kill a fleeting wounded
bird, but wherever and whenever it is used it will needed to be used
carefully as it will excel in its ability to put a hole in anything,
more so than lead ever could. One word of caution, this stuff will
penetrate well, very well, so bear this in mind when you sit with
200 yards of the next Fowler, especially if he is the one shooting
Hevi.
