Flex Hone – Improving Your Shotgun

Posted By on December 9, 2014

Flexhone_Barrel_Honeswcap We have found that even a chrome barrel and chamber have problems with sticky shells or shell residue build up, even after cleaning. When you put 400-500 rounds through your shotgun in a three-day period this can cause minor difficulties and even affect accuracy. There is now an easy way to make your chamber, forcing cone, and barrel as smooth as silk making those shells pop right out. We have even used it with Antique shotguns cleaning out rust and smoothing out pits.

This is a flexible, drill-mounted hone called the Flex-Hone® to quickly and easily produce the optimum smooth and polished surface finish in any type or size of shotgun chamber, barrel, or forcing cone.

Developed by Brush Research Manufacturing (BRM), Los Angeles, CA, the ball-style Flex-Hone Tool is characterized by small, abrasive globules permanently mounted to flexible nylon filaments. Using a flexible hone is a simple process that basically requires the means to hold a part securely such as a padded vise, the use of a low speed electric hand drill, and some common sense.

Available in a variety of lengths and grits designed to meet the various bore or gauge sizes of most types of guns, the Flex-Hone enables shotgun owners to achieve a rust-free, beautifully polished micro surface finish. As a result, many firearm manufacturers are today selecting the Flex-Hone for final finishing operations. However, the tool functions just as well in the hands of a DIYer.

Maintaining Barrels, Chambers and Force Cones
The Flex-Hone quickly, safely and thoroughly cleans out any barrel damage that has occurred from oxidation and corrosion, blend out scratches and removes the nicks and pits that cause plastic adhesion.

A flexible hone will also remove the built up residue in a barrel, and leave a superior surface resulting in greater accuracy, reduced wear and longer life for a shotgun. Standard barrel hones are 34 inches long and available in 10-, 12-, 16- and 20-gauge sizes.

It will also ensure that debris is far less likely to adhere to the chamber walls and any that does remain will be much easier to remove during the normal cleaning procedure.

The forcing cone can also be polished using a flexible hone with a specially designed tapered profile Flex-Hone. Forcing cones are the first thing the shot and wadding encounter as the transition is made from chamber to barrel, the cone literally forcing the larger diameter payload down to barrel size, so it is subjected to considerable force, as its name implies.

This can lead to considerable fouling build-up close to the cone, the surface finish of which can be less smooth than either the barrel or chamber, as manufactured. Not only does the fouling create added resistance but can induce corrosion to take hold under it. Even regular cleaning may not remove it all. Honing with the Flex-Hone will ensure fouling build up is minimized.

Shotgun Owner Feedback

Johnson, who had been utilizing professional services for polishing and finishing and paying the cost plus $75 in postage, tried the Flex-Hone.

“With the Flex-Hone, I accomplished the polishing myself in half an hour,” says Johnson. “This saved me time and money. If you can operate a drill you can polish your barrels, chambers, forcing cones and cylinders yourself. I followed the instructions and had no problems at all.”

Jim O’Hanlon, a cowboy action shooter form Port St. Lucie, FL had similar results.

“Using the Flex Hone simplified the cleaning process and gave more consistent results,” says O’Hanlon. “As a cowboy action shooter, we shoot double shotguns that are not allowed to have ejectors, just extractors. Shells must fall out of the chambers with ease for fast reloads.”

Hanlon adds that he also competes in Black Powder categories, which can create what he calls “a really sticky chamber.”

“The Flex Hone gives that final, glass like smoothness that allows my extraction of empty shells to be fast,” says Hanlon.

Art Kopp, Jr. of Great Bend, PA tells of shell-hanging problems occurring with his Remington 1187 20-gauge. “The shells were not ejecting,” explains Kopp. To determine if the issue was a barrel-related malfunction Kopp switched barrels with another 20 gauge and the problem disappeared immediately.

Knowing it was a barrel issue, Kopp was able to use the Flex-Hone at home. “I used an electric drill, elbow grease, and a Flex-Hone,” says Kopp. “After, my Remington 1187 Premier Upland Special was again working flawlessly with any rounds I put through it, including cheap aluminum-hulled ones.”

Delbert Murray of Victorian Arms of Pensacola, FL describes how frustrating it can be to clean the barrels of older shotgun barrels, included double-barreled.

“We seem to have a lot of people showing up over the last two years with Grandpa’s old double barrel,” explains Murray of Victorian Arms. “Some of these were very sad cases. We did what we could for the pitted barrels [using various techniques] and it was relatively easy to knock off the surface rust and chunks of hardened powder and residue. The disappointing part was the very minute pits and scratches that remained.”

Although eager to restore the barrels to a safe condition to shoot, Murray also understood that it was extremely important that excessive material was not removed and that no area was over-worked in an attempt to remove a particularly stubborn pit or rust. Having tried a myriad of techniques, Murray learned of the Flex-Hone and decided to put it to the test.

“We were a little skeptical at first about how well it could work and chose an old Colt double 12Ga of Damascus steel to test on,” says Murray. “It could never be fired again so we couldn’t do it any harm.”

Murray was instantly impressed with the results. “The Flex-Hone was like magic. Now we use them every chance we get and the result is almost always a bright, ‘like new’ barrel in just a matter of minutes.

Victorian Arms now stocks a complete set of Flex-Hones in various sizes for all shotgun gauges, as well as for the chambers.

“It pays for itself the first time it is used on a restoration job,” says Murray.

Dennis Weinman, of Cordova AK, had a similar experience using the Flex-Hone as part of a restoration of his 1870’s vintage W.C. Scott.

“Rusty bores were a major issue,” explains Weinman. “The Flex-Hone tool removed the surface rust completely from the bores. I would have paid a professional gunsmith good money to do what I did myself. I used the flexible hone with my old drill and motor oil and got a great result.”

Weinman was also impressed that the Flex-Hone was available in the exact bore size he needed.

“The shotgun was a 10 gauge bore, so the fact that [Brush Research] had a 10 gauge Flex Hone was a restoration life saver,” says Weinman. “Moreover, it was rewarding to do the work myself and it made the result even better.”
