"Everyone and his dog" has muzzle brakes and make all sorts of claims. In thorough comparative tests, some hardly reduce recoil at all while some are quite effective. My system has not been included in the tests I have seen, but I dare to say my system is the most effective and CERTAINLY the neatest, least obtrusive of all!

|.300 Win. Mag HANDGUN!!!!
And from my own past experience, a .300 Win. Mag. with my brake is more comfortable to shoot than the identical barrel in .308 Winchester!
It is not as crazy as you might think on first glance.
Read on, and I think you will understand why this is true.
And it is almost guaranteed no one else in camp will have one!
Paul's was not only the first handgun a client had used on this particular ranch, but having done the range time previously, he said he outshot all the guys with rifles, 3 out of 4 he said had missed game shots!
|Paul Long's mulie below ranks #7 in the Safari Club International Handgun category as of this writing, 5-30-2016.
Results and observations from Paul are enlightening.
Way to go!
|16 1/2" .300 Winchester Magnum shot as handgun, nice Colorado mulie shot at about 200 yards. Note the use of 3 scope rings, recommended.|
Some of Paul's comments follow:
" And yes it is very manageable. I am very pleased with the pistol, recoil, accuracy (I got 1 three shot 3 ĹĒ group at 300 yards), and donít forget the spring kit. The 2 pound trigger pull made a huge difference. I would recommend it to anyone who wants to shoot a handgun accurately at long distance. I might also point out there was a dozen trips to the range and hundreds of rounds to make that shot. "
" And for what itís worth I settled on Barnes Vor-Tx 150 grain TSX BT ammo. I seemed to get the flattest trajectory and tightest groups with that ammo."
"....you customized for me (rechambered, cut down the barrel, machined muzzle brake, and spring kit."
"I out shot all the rifles in camp." Ie., Paul did his homework, range time at long range.
Past experience with .300 Win. Mag. in 15" barrels gave an average 200 fps gain over .308 Winchester, same 150 gr. weight Remington factory ammo.
And, yes, you feel much less recoil and get much less muzzle rise from .300 Win. Mag. as you do from an unbraked .308 Winchester!
The key is muzzle pressure and the volume of gas making the brake do its work slapping the muzzle down and literally pulling the gun forward!
|The Best, Most Effective, and Neatest Way to Brake a Barrel!|
Cleanest, neatest appearance.
Nothing gobby or gawdy added on.
All work done on center, referenced off the bore itself to within .0005" of true center of bore axis, and precision single cut lathe bored, thus....
Nothing to be misaligned with the bore.
No unsightly bulge.
Uses only about 1 inch or less of effective barrel length.
Expansion chamber design machined inside the barrel.
Precision 11 degree target crown cleanly, squarely cut at the end of the bore inside the brake.
Can be positioned to clear a standard front sight.
Ports neatly aligned with flutes in fluted Pro Hunter type barrels.
Ports angled back 22 degrees actually pull the gun forward by converting the blast normally out the front of the barrel to a force propelling the gun forward.
Top row of ports have a very pronounced vertical angle for more control of muzzle rise. Side ports are positioned below the barrel center line to make more room for the top row of ports, but are on a true horizontal plane so the they do not blast dirt and debris in your face when fired from prone.
(Lower row of ports in the "Pro Hunter" fluted barrels are angled downward slightly, only 20 degrees, for better positioning in the flutes, but still direct the blast well away from the ground and away from the shooter shooting prone.)
Ample clearance at the exit of the brake lets bullet pass without disrupting its flight and accuracy, yet balanced to restrict and redirect the blast out the ports while the bullet is passing through the exit hole or "pupil."
Can be machined into any Encore or Contender/G2 barrel or any barrel I can run between centers in the lathe.
Now fixtured to do Thompson Center "Dimension" rifle barrels. I can also do any barrel that has sight screw holes or any other point I can reference off of for top dead center of the barrel. I can receive ONLY the barrel, so barrels MUST be removed from the receiver (or frame) and sent separately.
|My brake actually slaps the muzzle down! Your reflexes bring it back up to shooting position.
Just watch it being fired or cant your head to one side and watch the muzzle. Instead of rearing up, the muzzle makes a quick downward dip.
|Make Those Hard Kicking Barrels Pleasant to Shoot!|
|Note the clean cut on the rifling in focus at about 7:30 inside the brake|
|Clean, sharp, 11 degree target crown cut inside the brake at the end of the bore.|
Disregard the lint in the photo, but look at the end of the bore down inside the brake and see the distinct, cleanly cut profile of the end of the rifling where I managed to get it in focus at about 7:30.
All internal work is single point lathe bored with indexable carbide boring bars.
|How brakes work........
Here are some guidelines.
Let me start by saying that to advertise a certain percentage of recoil reduction is misleading. After reading the following, I think you will both understand why and better know what to expect.
1) All brake designs redirect muzzle blast to the side to reduce the "rocket blast" effect at the muzzle slamming the gun back.
2) As noted above, my designs literally pull the gun forward while also slapping the muzzle down, which you can see watching the barrel while being fired off hand. The muzzle is slapped down, then your reflexes bring the gun back to level.
3) No brake design can offset the inertia of accelerating the bullet.
4) The total effectiveness of my brake is dependent on both actual pressure at the muzzle and the volume of gas the powder charge generates. A faster burning powder in a .308 Winchester, for example, reaches its peak pressure farther back in the barrel while .300 Winchester with its slower burning powder maintains its pressure farther down the barrel with result there is both more pressure and a greater volume of gas at the muzzle. (This higher pressure over a longer distance clear to the muzzle is what produces "magnum" velocities, but also "magnum" recoil.) Thus percentage wise, there is a greater reduction of recoil from the magnum compared to the same weight of bullet fired from a .308 Winchester. Recoil from accelerating the bullet is greater in the .300 Winchester of course, but the pulling forward and pushing the muzzle down is also greater.
5) Effects of powder burning rate are readily apparent when I use faster powder in .357 Maximum test fire ammo. When I do the brake internals a pvc pipe sleeve is Bondo-ed onto the barrel. Bondo fills the ports. The easiest way to clear the ports is to simply fire a round. Extremely hot test fire rounds with faster powders in rifle length barrels will not even budge the Bondo from the ports at all. I have to go to the slowest powders proper for .357 Maximum in order to have enough pressure at the muzzle to blow the Bondo out of the ports! It graphically demonstrates the differences in muzzle pressure between faster powders v. slower powders!
6) Lower pressure rounds with heavy bullets in braked barrels give the least amount of recoil reduction and muzzle depression. Faster powders used in .45/70 and .460 S&W rifle barrels, for example, combined with heavy bullets are still going to produce substantial recoil and some muzzle rise. The best way to reduce recoil in these types of guns is with more weight to offset the inertia of accelerating the bullet.
7) Rounds with larger volumes of faster burning powders such as in .460 S&W handgun barrels maintain both a high pressure at the muzzle and larger volume of gas making them very effective. However, the extremely light weight TC factory .460 barrels still recoil substantially simply accelerating the bullet, but muzzle rise and overall recoil are dramatically reduced.
8) Rifle type rounds like .308 Win., .270 Win., and .30/06 in handgun barrels give good recoil reduction due to lighter bullet weights, the relatively large volume of gas, medium burning rate powders, , and maximum pressure at the muzzle. These are very effectively tamed down with my brake design.
9) Probably least effective is braking a muzzle loader barrel, but still something I do on request. Internal diameter of the brake is kept minimum and no expansion chamber is machined in. The object is to minimize potential problems with sabots passing through the ported area. To date there have been no accuracy complaints concerning the muzzle loader barrels I have braked, but I make no claims regarding accuracy from muzzle loader barrels with my brake.
10) Force over a longer period of time produce more recoil from accelerating the bullet. Thus the heavier the bullet and the longer the barrel, the more recoil from accelerating the bullet. Meaning, you will find more recoil reduction from the brake in shorter barrels v. longer barrels. And of course the shorter barrels will have more pressure at the muzzle compared to the same ammo in a longer barrel.
1) The lighter the bullet and the greater the volume of slow burning powder in rifle length barrels, the more effective the brake is.
2) Conversely, there is less perceived recoil reduction in rifle barrels firing faster powders and heavy bullets.
3) Shorter barrels give more recoil reduction than longer barrels. Handgun length barrels, especially with lighter bullet weights, firing high pressure rounds give the most reduced recoil and muzzle rise.
4) I'm not a mathematician but dare say advertised percentages of recoil reduction published by others are probably not valid since they do not take all factors into account for all conditions.
|One of hundreds of .444 Marlin barrels I done with my machined in brake.
.444 Marlin in a light Contender barrel is brutal to shoot without a really effective brake! With my brake shooters are able to milk outstanding accuracy from 14" Contender handguns, even without the weight of a scope to help mitigate recoil.
.444 Marlin represents THE most horsepower you can get out of a Contender, and my brake makes it entirely manageable!
This gun was used to take a 220 pound black bear with one good controlled shot by Pete Kolovos, shattering the shoulder and taking out the heart.
Quoting Peter, "The devastation this round caused on this Bear was incredible. The 265 grain Hornady broke the shoulder, blew the muscle in his left front leg apart, and pierced the heart. We never found the bullet."
6 scope base screws are a must to keep scope base screws from stripping out under the recoil of .444 Marlin. Base is standard Weaver base, converted to and installed with 6-screws.
Over the years, particularly during the 1990's, I did a lot of .444 Marlin 14" Contender barrels set up with aperture rear sight and shot a lot of them off the bench verifying correct sight heights. Without a scope, and with the weight of the barrel reduced substantially by the large bore, a .444 Marlin Contender offers little weight to offset recoil of the mighty .444 Marlin.
With my brake, shooting off the bench and taking full recoil, I find the .444's recoil quite manageable. (Mike Bellm)

You can easily shoot this barrel one handed with full house loads. The accuracy speaks for itself.

This was a heavy stainless .375 JDJ factory rifle barrel I cut to carbine legal 16" length, machined my brake into, and rechambered to .375 H&H. Forend is the factory rifle forend. Barrel is drilled and tapped to also take a forend for 15" handgun.
Recoil is a hard push back, virtually no rise at the muzzle. Easy enough to shoot one handed!
|Brake Closeup. Large 3/16" diameter ports, 3 per row.Note the soft, fine sand blast matte finish.

|.300 Win. Mag. 26" stainless steel heavy barrel.3/16" ports. The 26" stainless .300 Win. Mag. factory production barrels are proving to be some of the straightest TC production. When running barrels between centers in the lathe, how straight a barrel is becomes very apparent as it is turning. Most all barrels have some degree of warpage to them, but most of the .300s in the heavy stainless 26" configuration are very straight, inside and out as of this date, 6/2006.
These should be accurate barrels and once the bone jarring, stinging recoil has been removed with my machined in brake system, they should make excellent hunting barrels. I'm inclined to buy one for myself!
|Shoot a.45/70 10 inch barrel? Yes, and comfortably!|
Obviously, stiff 400 to 500 gr. loads are going to recoil quite heavily, but normal Contender 300 to 350 gr. loads are quite manageable.
Normally I would decline such a project, but this .45/70 barrel, cut back to 10" was for a special application, and turned out to be quite interesting.
|Extra ports for large cals, large capacity magnum cases|
This system with a total of 16- 3/16" diameter ports, 4 per row, is for larger bore sizes from .44 cal. up and larger cases. I chambered this particular 18.5" Encore barrel in .458 Lott Encore and fired one handed as a handgun with 70 gr. of Rel. 7 and 300 gr. bullet.
Very little muzzle rise, quite a bit of torque, and a generous shove back, but VERY manageable and not uncomfortable. That said, at my age carpal tunnel is something I am more conscious of, so unlike the days in my 20s and 30s, I wouldn't sit there and shoot one all afternoon inviting a sore wrist. But I would have no hesitation to become proficient with it, work up good loads, and use it on a serious hunt where this much horsepower and penetration are in order, even as a handgun.
|The .458 Lott cartridge is one of my newer chamber offerings.|
For all you wannabee Quigley Down Unders, the Lott is basically a modernized .45-110 nearly identical to the Sharps Matthew Quigley used in the movie, but using a belted case. Ie, most likely a belt counterbore could be cut in the end of a .45-110 chamber, and the .458 Lott would fit perfectly...... though not recommended for a Sharps type rifle of course.

|How effective are my muzzle brakes? Here is what my customers have to say about them.|
Muzzle brake reduced recoil level of the .35 Whelen to that of a 270 or less. Shoots well. No problem with 1 to 1-1/4" at 100 with 225 Noslers at 2300. Many thanks.
You just did an in barrel muzzle brake for me, shot it last Sunday. Really made this 15 inch 30-06 a joy to shoot.
