Below: our longest-serving still shooting club member receiving the fine trophy awarded for the new club Benchrest Championship - won against determined opposition. The "King's Cup" will doubtless prove to be the perfect means of encouraging club shooters to not take a competition challenge lying down.
With the exception of the club captain on the right, the winner and the cup are the two tallest features in the photograph.
The progression of CRC Team and equipment
thro' their first season in 2023.
Three amateur BR exponents at first practice for the 50mtr Leagues
- early Summer 2023
An early season session
with a modified BSA International MK.III
Already pictured in the preceding championship photographs,
we make no apology for again showing the senior team member,
and instigator of benchrest shooting within the CRC,
with his excellent personally acquired purpose made bench.
The 50 mtr. upper range used by the team.
THE EARLY DAYS
Foreground: Mk.III BSA International; custom-made dismountable bench.
Centre: Modified Walther KK200 ; custom-made folding bench.
Background: Anschutz with purpose-made proprietary benchrest stock and bench.
With the upper 50mtr range occasionally presenting particularly trying weather patterns,
a discussion was had on the possibility of an improved wind flag layout,
such as that seen elsewhere.
INDIVIDUAL EQUIPMENT
A bench is obviously needed, and can be home constructed.
And a not too expensive rest is required.
Not to mention a stool.
No, this is not the same one as in the clubroom,
but an identical one bought from a charity shop for £5.
The feet were later made finely adjustable with the insertion of four bolts
to accommodate uneven ground,
as the stool next became an integral part of the stability of the table.
More sensible and better balanced shooters use a three-legged model.
A target frame can also be knocked up from plumbing parts,
along the lines of some existing club equipment.
The above light-weight collapsible bench can be seen behind.
(The description of the latter has been carefully chosen.)
Another team member produced a really substantial version, and a milking stool,
later swapped for a new circular height-adjustable three-legged model.
An early rifle candidate was a BSAMartini International Mk.III
shown here in the club's test bench.
Various inventive butt configurations have been tried over the Summer months,
here being a design for a long under-butt hand support for a BSA Martini Internationa Mk.II..
Susequently changed to a MK.III International, the butt was further modified
using an Anschutz Supermatch adjustable cheek-piece, and an improved hand support.
A close-up of the design shows a further modification to the butt-plate.
To convert a prone rifle for benchrest use,
you could even just switch round the cheekpiece and buttplate units.
Perhaps surprisingly, a cheek-piece has proved to be not really necessary!
A borrowed tuner is prepared for experimentation.
Should using a normal pistol-grip hold seem to cause unwanted movement,
a "pinch" let-off between finger and thumb can be employed
with the necessary adjustment being made to the furniture.
Another early candidate was the Anschutz 2013 that once belonged to a late club member.
Later, a Walther KK200 was modified for use on the bench.
The lower butt support was the Mk.I.
Later the butt support was lengthened,
and the rifle is here shown under test.
The Walther's 50 mtr. test card during which weights were moved up and down the barrel,
while group testing with both R50 and Centre-X ammunition.
Yes; the position of the weight makes a huge difference
The group testing target frame for the 50mtr. range.
Telescope sights already possessed were tried,
but a higher magnification than the usual 25x proved particularly worthwhile.
A (sadly Chinese produced) 'scope was the most economical option -
- a Vector Minotaur Gen II 46x60 model for less than £400, compared with the
more often favoured Sightron equivalent model at nearly four times the price.
The Vectron has an illumonated red dot reticle. but this is no advantage for benchrest
unless you are trying to shoot after dusk.
The plain target dot is far preferable.
The 'scope has 1/8th. minute clicks - only just about sufficient.
(The costly Sightron now comes with 1/10 MOA adjustment.)
The Walther ready for the off.
Having been fitted with a tubular attachment to the accessory rail for stability on the rest,
with no interference to height adjustment during a shoot.
It is possible to purchase a rest, at a price, that permits both elevation and windage adjustment.
This was a type considered.
But one team member opted for a brand new item that would adjust in both planes,
although the windage knob was all but out of reach without laying down the rifle.
Means were sought to put adjustments within easy reach,
and these fine wheels were offered by one kind team member.
Desperation brought one team member to make a significant purchase,
here shown on its arrival. More of which later.
Here the earlier Anschutz in the foreground has its cheek-piece used as a butt-plate,
and the butt-plate used as an adjustable hand rest.
The well-known competitor who had acquired at auction a particularly good-value
almost new Anschutz "Perfection" model with a good 'scope included,
(retiring his trusty Leupold for the time being)
improved stability by the addition of a large aluminium beam to
replace the over-flexible and once expensive proprietary
benchrest ladder frame that came with the rifle from new.
The consideration of "pinch' trigger let-off led to the modification shown below,
a component of which may be recognisable to historic rifle shooters.
Not entirely happy with the arrangement, an alternative pistol-grip was designed and tested.
Further consideration was given to the butt arrangement,
with a fine curved under-butt hand rest being engineered.
The above design allowed an unintended lateral "roll" to the hold,
and a flatter, warmer amendment took place.
But proving too short 'front-to-back there came a further alteration.
One member's further project has been the building of a one-off BR rifle.
Requiring the removal of an Anschutz 2013/2007 square action from its donor rifle.
The acquisition of a new 21" barrel by Lilja.
With its ability to rotate same to obtain the best harmonics regardless of extractor position.
Clamping into the action.
The purchase of a new all metal stock.
A barrel tuner.
A sleeve to adapt the tuner to the lesser diameter of the new barrel.
The test fitting of the action to the new stock, prior to stock completion.
The careful bedding to permit access to the trigger!
Shaping of the stock.
Test fitting of action and 'scope.
Frontal view, with tuner in place.
The elegant trigger-guard, designed for a thumb/fore-finger 'pinch' let-off.
Trial on rest now modified to permit elevation adjustment using right hand,
allowing left hand to remain under butt between shots.
Stock finishing in the spray-shop.
Barrelled action fitted into finished stock.
Trigger unit complete.
Showing the rear four of the action's six bedding bolts.
A first trial and 'scope setup was achieved at a superb local 15 yard indoor range.
The 10-shot 7.2mm group shown below was shot at 15yds
on an NSRA diagram on that occasion.
The diameter of the 15 yard bull is 9.85mm.
Further group improvement and barrel tuning was undertaken using the CRC test bench at 50 mtrs.
Then first target trials on the upper 50 mtr. range.
The bench setup - showing elevation wheel gear extension now within easy reach of right hand.
Already modified to permit its height adjustment to be more easily made with the right hand,
as previously mentioned, it was decided to modify the rest to also have
windage adjustment by fitting a lead-screw underneath that linked to a sliding plate on top.
The sliding windage plate.
Arranging the gear linkage meshing to accommodate the accompanying
elevation adjustment proved tricky, although a sprung setup made this possible.
But the similarity to some of Roland Emett's and Heath-Robinson's inventions was likely
to cause mirth and unwarranted critical comment on the points.
So an alternative method was decided upon, using a right-angle gearbox
gifted by a friend who had motorised his previously hand-operated honey stirrer.
Operated by a model aircraft wheel, the system cunningly and
automatically adjusts position as the rest is raised or lowered.
As may have been spotted above, the new girl has been named for the barrel, the action .....
............ and the girder to which they have been mounted.
Here first used in competition on the indoor 25 yd. range.
And, outdoor at 50 mtrs. - showing the business section.
The most recent modification has changed the rifle from using a free-floating barrel
to a clamped type, approximately 2/3rds. of the distance from breech to muzzle.
A 1-inch 'scope ring mount was used.
Twin o-rings are heavily clamped to the barrel,
permitting a flex of only about three 'thou' in each plane.
After fitment of the barrel clamp, a 25 yard test provided a ten-round 8mm group.
This is NOT equivalent to a 16mm group at 50 mtrs,
as a group that would be formed at the muzzle at zero range starts at approximately 5.6mm!
The lower group was prior to a tuner adjustment, proving that, even with the barrel
heavily damped at approximately 2/3rds. along its length,
a tuner remains surprisingly effective.
A good 25 yard practice card, (sadly and typically not a comp. card), is shown below.
With an evident need for more a more stable table, an approach was made
to a Northern supplier, who kindly brought two down for the club. (Not free).
Himself a worthy and successful benchrest shooter,
he brought his kit to demonstrate how our highly competitive opposition operate.
Photographs were surrepticiously taken, in the F1 manner, to afford later scrutiny.
With close-up shots of his 'scope .....
......... and his expensive tuner.

This elegant poor creature is threatened with retirement after only a few months.
The first sign of a new development - bar none!
The prototype of the latest model of "LEK" rifle - the 'LEK BR Special'.
Not exactly a hole in one.
Who bought an aluminium girder too long to fit across the lathe milling head?
Small bore activity?
Are you cut out for benchrest?
Evidently an attempt to Racer head.
Who among us can see the similarity to a Swedish 1896 Mauser?
The long and the short of it ............
....... and a sneak view of the aerodynamics of the undertray,
with the array of titanium bump stops that will shower sparks on the track.
After tidying in the filing cabinet.
Well, someone is pleased!
The test rig on the 25 yard range!
No sign of extraneous accessories;
just a clean-lined lightweight model of a heavy BR Rifle!
And, in the best tradition, the new girl is not completely devoid of fine timber,
well-seasoned hickory,
which carries her carefully chosen name - "Faithful".
And, what's more, she is living up to all prospective hopes,
with a first test card (BR, not BBC) showing a score of "100.7",
worryingly challenging for competitors considering she has yet to be "tuned"!
The next uplifting requirement is for a new slant in butt elevation systems.
For which the engineer, after drilling many more holes,
must tap into all his resources .......
.......... including cannibalised Anschutz parts,
and perhaps more hickory,
unless you have used it all and find something else.

NEW BENCHES as of May 2024
This excellent professionally produced collapsible portable bench replaced the old home-made folding model that was frankly insufficiently stable, showing significant movement through the 'scope around the target, particularly when moving to adjust the elevation and returning to the firing position.
But even the heavy, stiffer new table showed more than ideal movement in the same way, with the rear of the bench table only being supported centrally. This allowed a warping twist across the bench near the elbow, arm and hand resting points that showed up in the telescope's sight picture.
Stiffening folding supports have been added either side to alleviate problem and reduce the movement.

LATEST
2024 to 2025 WINTER SEASON
Part way through the Winter Leagues, the original homebuilt stock
has been used to mount another Grunig and Elmiger Racer 3 barrelled action,
and fitted with with a Sightron 45 x 45 'scope replacing the Minataur.
This became necessary due to difficulties finding ammunition
that suited the Lilja barrel when the supply of R50 ran out;
in fact, practically any ammunition at all!
The Colchester team now has two members with home-built BR setups using G&E kit.
With one using a fine new SEB rest
Both rifles were group tested in the club's test clamp bolted to a Yorkshire bench base frame.
The butt arrangement of this rifle has been further modified to improve hold comfort.
Ammunition tests were undertaken of Eley Tenex, the clubs' S&K Target, and Lapua Centre-X
The test card shows groups for both the Tenex and Centre-X ammunition.
Only one Tenex batch was available, but two of Centre-X.
There is a KEY top right identifying the abbreviated captions under each group.
The tests were started with the tuner at a previously used position deemed "zero".
The "TB" or "TF" relates to Turns Back or Turns Forward from that zero position.
All are five round groups except that asterisked - which is ten.
The "R" figures indicate the number of barrel weight 'Rings' (or none) fitted for each group fired.

The best group obtained is shown close up below,
at two turns back from "zero" with three barrel weights fitted.
____________________________
In the meantime, an old club rifle has been modified as a spare for any club BR newcomers.
The 2007/2013 action was fitted with an Anschutz 1813 barrel with a low shot count
and which had previously been successful in competition.
The barrel was reduced in length by about two inches with the rear reduced diameter, that locks into the 2013 action, recut to a fine tolerance into the body clamp, a coned breech section, and rechambered with a match target reamer. The crown was still in fine condition.
The 'scope is the particularly economical and effective Minataur 45mm x 60mm with Target Dot.
The resulting setup proved highly accurate, and precious little behind the new G& R rifles in group tests.

Approximately an 8.5mm group of 8 rounds was obtained at 25 yards,
compared with that for the G&E Racer 3 of 8mm.
The very first practice target shot with this rifle
________________________
As of mid February 2025, the hitherto rather agriculturally modified Caldwell rest
was replaced by an old 2008 SEB model purchased very reasonably second-hand,
and on which an extended elevation adjustment was arranged
to obviate the need to remove the left hand from beneath the butt
between shots when adjusting elevation.
This initially consisted of a rubber-tyred pulley-type wheel machined up and mounted on
a spindle passing through an additional plate fixed beneath the main block.
The wheel, at the front of the rest, ran on the original horizontal alloy elevation wheel
which had been knurled on the top edge, raising and lowering the rest
as the extension spindle was rotated.
A later amendment, to fit a smaller rubber wheel, lowered the gear ratio,
permitting finer adjustment.
Whilst the above arrangement worked comparatively well,
it was decided to engineer a more positive system, and a bevel gear set was acquired
and fitted in place of the original alloy knurled wheel.
After initial testing, which revealed some tight spots in the gear meshing,
careful swiss-filing and polishing with a buffing wheel has resulted in very smooth operation.
The rest has now been used quite successfully.
