Longthorne is a shotgun manufacturing company located in Northampton, UK. They make high-end over and under and side by side shotguns. This company is a relatively new one. It was established in 2010. What sets them apart from other companies is that they widely use modern technologies and unique design solutions. Particularly, they machine both barrels of double-barreled shotguns from the same solid block of steel!
Normally, double-barrelled shotgun barrels are made separately and soldered to each other with a rib sandwiched between the barrels to ensure larger contact surface between the two cylinders. Longthorne does it differently. They take a solid block of steel and machine both barrels out of it. So the two barrels are not attached to each other but are a single monolithic part. According to Longthorne, this technology allows them to make stronger, more accurate and lighter barrels. The material left between the two barrels is less than two millimeters (.08″) thick.
This technology itself is not anything new, which the company admits. According to Longthorne, the idea of barrels manufactured from a single piece of steel was patented in 1857 by a gentleman named Joseph Whitworth. However, the manufacturing methods and machines wouldn’t allow making such barrels back then or they would be extremely time consuming and expensive. With the modern machining equipment, making such barrels became relatively easier.
Longthorne shotguns come in 12, 16, 20, 28 gauges and 410 bore. All the caliber options feature barrels with 3″ chambers except the 28 gauge, which has a 2 3/4″ chamber. The prices of these shotguns start from £17,400 (about $24,500) as seen in the company’s current price list. Click here to get their brochure and price list.
