Change Out Your Barrels Quickly and Easily with Muzzle Mod

Warren Dean Hex Barrel John Whidden Larry Racine

Competitor Warren Dean has employed a hex-end barrel to permit rapid barrel changes on his F-Class rig. Warren wrote: “I have been running what is commonly known as a switch barrel on my F-T/R rifle. Basically it allows for removal and reinstallation of the barrel with basic hand tools and with no, or very minimal, shift in zero. The two gunsmiths that I trust, Larry Racine and John Whidden, both told me that the switch barrel system would return to a very close zero with no problems. [This system] can be a great benefit to the traveling shooter and a money-saver for the shooter wanting to shoot different calibers on the same chassis.” READ Dean Switch-Barrel Report.

Larry Racine Barrel Sytem
Larry Racine is a respected gunsmith based in New Hampshire. He is also a two-time member of the U.S. Palma Team, and a five-time New Hampshire State Highpower rifle champion. Larry, who runs LPR Gunsmithing, has developed a brilliantly simple means of switching rifle barrels with an ordinary spanner or open-end wrench. With this set-up you can switch barrels in the field in seconds without the need for a barrel vise.

For most barrels, Larry mills a hex with six flats on the end of the barrel. This allows a shooter to change barrels quickly at home or on the line with a simple box-head wrench or a socket wrench. Larry says: “You don’t even have to take the barreled action out of the gun. Just set the buttstock on the ground, between your feet, put a wrench on it, hit it with the palm of your hand — and off comes the barrel.” For barrels fitted with a muzzle brake, Larry has a slightly different system. He mills two flats behind the brake so you can use an open-end wrench to do the job.

With either a hex on the end, or two flats for a brake-equipped rifle, the system works with any medium- to heavy-contour barrel with a muzzle-diameter of at least 0.700″. This will even work for high-power rigs using clamp-on sights or bloop tubes. Larry explains: “A lot of us here in New England use clamp-on front sights. The barrel will be turned to 0.750 for the sight, with the hex on the end. A bloop tube can go right over the end, no problem.”

Larry has used this system over the past few years to win a number of matches. In one 600-yard 3 by 20 prone match, Larry used three different barrels, with three different chamberings, on the same Savage rifle. Larry changed the barrels on the line.

Larry was able to do this because the system has little to no loss of zero from one installation of a given barrel to the next installation of that barrel. This lets the shooter start the match with confidence that the first sighter will be on paper. Larry reports that the simple system works great: “To date we have used this system on Savage, Remington, Winchester, RPA, and Nesika actions.”

Varminters Take Note — This Is Great in the Field
If you are a varminter shooting hundreds of rounds in a day, consider this system. We know some guys who bring 3 or 4 rifles into the field because their barrels get hot during long days of prarie dog hunting. With this smart system, you can easily swap barrels in a couple minutes. And no special equipment or barrel vises are required.

Modifying Barrels is Affordable
Racine’s system for rapid barrel removal/changing is very affordable. If Larry does the chamber work on your barrel he charges $45.00 extra to mill a hex or two flats on your barrel. The customer chooses the configuration.

If you only want the hex or flats done, Larry may charge a higher fee — call for current rates. Note this can also work for barrels with muzzle brakes or threads for suppressors. For more info, visit LPRGunsmith.com or call Larry at (603) 357-0055.

Cheap Tricks: How to Measure Shoulder Bump Using .45 ACP Case

.45 acp pistol case bump gauge headspace tool

Here is a simple, low-cost way to get reliable readings of case headspace when you “bump” the shoulder back on your 6BR, .243 Win, or .308 Win brass. Credit Boyd Allen for this tip. First, you’ll need one .45 acp case, with primer removed. Make sure the .45 acp case is trimmed square and that it is round. We recommend you first run it through an expander, then size it, trim it and chamfer. Next, take the .45 acp case and slip it over the neck of a fired, unsized rifle case with the primer removed. Align the two cases between the jaws of your calipers and note the length from rim to rim (See photo below, with striped case).

OK, now you have the length for a fired rifle case BEFORE sizing. Next, take a full-length sized rifle case (without primer) and do the same thing, placing the .45 acp case over the neck of the FL-sized case (Bottom Photo). The difference between the two numbers is the amount of “bump” or set-back you are applying to the shoulder. Here the difference is .0015″. The amount of bump you need varies with your chamber and your load, but .0015-.002″ is a good initial setting. By using this simple tool, you can avoid bumping the shoulder too much. This will also help you set-up the depth of your full-length die to get the proper amount of bump each time.

Not Just a Guy Thing — 23% of U.S. Gun Owners Are Female

Women & Guns magazineHere’s an interesting statistic — according to an NSSF survey, the percentage of gun owners who are female has increased dramatically since 2005. Seven years ago (in 2005), just 13% of U.S. gun owners were women. By 2012 that number had risen to 23% — a huge increase in less than a decade.

The vast majority of first-time female gun buyers acquire a handgun for defensive purposes. However, the statistics also show that many new female gun owners are also getting involved in sport shooting and/or competitive shooting. That’s a good thing.

In the video below, NRA News host Cam Edwards interviews Celia Bigelow, who has written about the rise of gun ownership among ladies on the Townhall.com website. Celia explains why American women are arming themselves, and why the Second Amendment safeguards a key fundamental right.

Celia Bigelow Fox News gun controlCelia writes: “As the number of proposed gun-control measures increase rapidly across the country, the amount of women purchasing guns is increasing even faster. While folks in the media are blaming the spike on the guns-and-glam advertising, women — including myself — have a different reason. It’s self-defense, stupid. [T]he logic is simple: Women want to protect themselves and their family, and guns are the great equalizer between sexes[.]”

Celia notes that liberals propose that women defend themselves using “call boxes, ball-point pens, whistles, buddy systems … as long as it isn’t very sharp and doesn’t have a trigger.” Celia is not convinced: “As a young, 22-year-old, 140-lb woman, I know that call boxes, pens, and whistles won’t do much good if [I am] ever faced with a crazed man twice my size. What frustrates these male elitists the most is that women are arming themselves, and it’s working.”
