In 2014 after an absence of 12 years we have reintroduced Bill Sinclair’s original LOADMASTER. Bill invented the LOADMASTER in the early nineties and Sir Joe Nickerson gave it his seal of approval with the words ‘ the best innovation in the shooting world for 30 years ‘.

The LOADMASTER is the solution to those who wish to speed up their reloading; it is an oblong leather covered ABS plastic box, which is divided into two upright sections, each of which holds 20 x 12 bore cartridges. The cartridges are stacked vertically in a zigzag column which allows gravity to feed them to the loading ports at the bottom.

The LOADMASTER is reloaded in each chamber via a central slot that runs vertically down the middle of each.

The Loadmaster is the solution to those who wish to speed up their reloading; it is an oblong leather covered ABS plastic box, which is divided into two upright sections, each of which holds 20 x 12 bore cartridges. The cartridges are stacked vertically in a zigzag column which allows gravity to feed them to the loading ports at the bottom. The Loadmaster is reloaded in each chamber via a central slot that runs vertically down the middle of each. After the cartridge is pushed into the slot it settles to one side so it doesn’t fall out. Gravity pushes the cartridges downwards to the loading ports at the bottom. The bottom of the Loadmaster has 45 degree sloping sides which channel the cartridges from each side to the middle where the loading ports are situated. This means we always have two cartridges offered together, heads outwards, which can be pulled out by the shooter either singly or in pairs. When they are removed, gravity feeds the next cartridges downwards to repeat the performance.

SO SIMPLE!! Between drives the two cartridges at the ports are held within the Loadmaster by a leather strap which is attached by a ring stud to the front of the Loadmaster. The secured strap blocks the two loading ports and retains the cartridges until you arrive at the next stand when it is released.

The Loadmaster was designed nearly 40 years ago when bag expectations were considerably smaller than nowadays. the capacity of the standard Loadmaster at 40 12 bore cartridges is a comfortable maximum weight for the single gun, however the Loadmaster has proved an essential tool for many guns shooting double guns with a loader. We have now addressed the problem of capacity with a simple solution, we join 2 40 capacity Loadmaster’s together with wide velcro strips, so doubling the amount carried from 40 – 80 12 bore cartridges. Perhaps a few words from Brian Scott:

Hi Peter sorry for the delay in reporting back, I’ve done 6 days loading on the grouse using the double loader and it’s spot on, holds 84 cartridges more than enough for a grouse drive this season.

Filming has been a challenge with the weather but have managed to catch the benefit of the loadmaster in the grouse butt, it’s ease of use and highlighting the freedom of movement you have while wearing it.

The extra weight is hardly noticeable, cannot wait to use it on the pheasants.”

The capacity of Sinclairs Loadmaster is 40 x 12 bore, 44 x 16 bore, 50 x 20 bore and 54 x 28 bore cartridges, great for both Loaders and single guns. Sinclairs Loadmasters are available in three grades – canvas and leather, standard leather and premium leather.

Each Loadmaster is supplied with an olive green adjustable strap but if you prefer we can supply any Guardsman strap at a cost of £20 plus vat. Please refer to our strap section to make your choice – I would suggest a strap no wider than 2 ¼” as the wider straps don’t mould to the chest as well as the narrower ones and this may interfere with your gun mount.

SINCLAIRS LOADMASTER is covered in either Sedgewicks best bridle leather, standard leather or canvas and leather.

The PREMIUM is offered in either Sedgewicks Conker or Dark Havana, The STANDARD in either Cognac or Dark Brown and the CANVAS in dark green canvas with dark brown leather trim.

The LOADMASTER works well with 12 and 16 bore cartridges, but to get the best efficiency with 20 and 28 bores we use INSERTS, these are 4mm thick  plastic spacers which reduce the width of the chamber space and they slot into the side walls of the Loadmaster, they are removable so allowing any calibre to used with very little modification. We use ONE PAIR for 20 bores, which attach one to the inside of both outer walls and TWO PAIRS for 28 bores, which attach to both the inner and the outer walls of both vertical chambers.

Within my lifetime I think we are now on the third book of Game Shooting. Times have changed and gone are the Gentleman’s days of the 70’s when 100 driven birds were considered to be a perfectly good days sport. In the 80’s and 90’s we had a period when bags increased (doubled) and the cartridges fired increased proportionally.

We are now at a time when bags are ever greater and quality is significantly higher which means more cartridges fired in a day and this can be 3 or 4 times the quantity of that of 30 years ago. Clearly I am generalising but many Gameshots are now regularly experiencing what the Edwardian sportsman called a “hot corner”; if you wish to enjoy these hot corners and maintain your share of the sport; then clearly the ability to reload quickly is paramount and deserves some serious thought. Out there, there is plenty of advice on how to shoot straight but I don’t think I have ever seen advice on reloading. I am sure you know plenty of people who seem to have the knack of reloading quickly and as a consequence get far more shooting than is good for them! Why don’t you join them?

    The inserts for 20 guage were not with the package as advertised . The receipt also showed the insert included . There were no inserts.

      Hi Cameron
      Thanks for the feedback..I have checked your order and you didn’t order inserts, you only ordered the Premium Loadmaster.
      The title of the page includes several items,from which you can choose, so this may have caused the confusion.
      To confirm, the price of the premium Loadmaster is £350 including 20%VAT, which means that the price to you is £291.66, which is the price you paid.
      I am sure this is a genuine mistake so we will send you the inserts and shipping FOC tomorrow.Peter

    I love my old style leather covered model, but the new larger design in canvas and leather is very practical and very well designed.

    I bought a Loadmaster at the Game Fair in 2018 and have been using it this season. Much faster loading than grabbing staubs out of a cartridge bag. Holds 50 20gauge cartridges so enough for a drive or two. Love this item and a staple of my game shooting kit now

    Ordered in the afternoon, came next day. Great service.

    Received my new leather loadmaster this morning (express delivery). I was very impressed with the quality and finish of the new higher capacity version (40×12 gauge) which will be very handy during the bigger grouse and pheasant drives. Very fast and smooth to load and extract cartridges so no excuses for not being able to reload quickly and put the next brace in the bag.

    I am interested in your new improved loadmaster. My partner uses a 20 bore and 28 bore.
    Can you confirm that it will be suitable for both bore cartridges. Thank you.

      Hi Paula,
      Yes, the new design of Loadmaster will allow different thicknesses of plastic spacers ( removable inserts ) to be placed inside both vertical chambers and these inserts will make the different diameters of the 20 and 28 bore cartridges stack at the preffeered 45 degrees to each other, so giving downward thrust without jamming and a perfect feed to the loading ports – I hope! Peter
