I am considering the purchase of a rifle with factory original Mag-na-port slots in the muzzle. It is a .416 Rem Mag, so less recoil and muzzle flip would be a benefit, but I strongly dislike any increase in muzzle blast and have removed any muzzle brakes that were installed on my hard kicking rifles in the past. I'd rather deal with recoil than the increased ear damaging noise. I only shoot while wearing muffs or plugs but still notice the difference with braked rifles, and bystanders may not be wearing protection. In addition, this rifle will be used on Safari and most African PH's dislike muzzle brakes and ask clients not to show up with a rifle so equipped. So I need your advice. Does a rifle with Mag-na-port slots increase muzzle blast noticeably like a screw on brake does? Difference for the shooter and for the bystander? Your experience appreciated.
 
LW..........I have several rifles with original Magna port and a couple from the previously licensed practitioner in Winnipeg, who developed a 6 port system which got him in deep do-do with Magnaport USA. Anyway, I don't notice any increase in noise at all as the shooter however benches both sides certainly do. I think if you call Magnaport US they actually have the testing saying that shooter noise is not increased.
I love Magnaport, it definitely reduces muzzle lift and thereby reduces perceived recoil and it is almost unnoticeable aesthetically speaking. I have hunted Africa several times with my 300 Wby and several other Magnaported rifles........never ever got a hard time from my PHs.
 
As the shooter, you wont notice a big difference in noise but anybody in close in proximity on either side of you will.
Definitely reduces muzzle lift and recoil to an extent. Very similar to a brake.
 
It's a muzzle break of course it's loud also one of the most efficient ones.I had a Ruger 77R in .338 done and simply wrapped the muzzle with masking tape to keep out snow and hunted with it.Recoil like 30-06 noise like a Panzer.
 
I have had 3 rifles with mag-na-porting. A 338 Win Mag, a 340 Weatherby, and a .375 H&H. I have hunted with all 3 without hearing protection (probably why I have hearing impairment now, lol) and did not notice any increase in muzzle blast from before they were mag-na-ported, A friend also had his 7mm Rem Mag mag-na-ported at the same time, and the only difference he noted was that he could now see his bullet strike the game. I have also had a 308 Norma Mag which I got a gunsmith to backbore the barrel and do an integral muzzle brake to remove a ringed barrel 1" from the muzzle. I bought the gun used with a dirty bore and didn't notice the ring until I cleaned it. After machining the integral muzzle brake, the rifle shot well but the noise was horrendous even wit muffs. It absolutely shrieked, as did a Sako TRGS in 338 Lapua which I had a brake put on to tame recoil. Sold both of the braked rifles, but would have more Mag-na-ported if there was still a Canadian shop licenced to do it. When I got mine done Joe Undiks in Winnipeg was offering mag-na-porting service in the early 1980's.

I love mag-na-porting (not a lot of recoil reduction, but noticeably less muzzle flip) and I absolutely detest muzzle brakes. Just my opinion!
 
have a 3006 rem 7600 with magna and I absolutely love it ! didn't notice much sound difference but i did notice a big difference in muzzle jump ! keeps the rifle close to on target for quick followup shots

also had an 870 barrel done .. n force cone lengthened .. hard to notice much in that case

I wouldn't call magnaporting a brake...maybe that's why the offer a magnabrake
 
Magna Porting and muzzle brakes do not increase the noise level.... they do however change the direction of the blast and if you are anywhere near a surface that will bounce the blast, it may appear to be louder than the bare muzzle but the noise level is not really louder.

The thing I don't like about Magna Porting is I have seen many barrels with damage in the area of the ports caused by dust/debris in the ports settling in the rifling and causing damage when fired... eventually affecting accuracy. A hard area to clean... brushes push debris into the ports and pressurized air is needed to clean the ports so the residue doesn't seep back in. Magna Porting also is not as effective in reducing recoil as a muzzle Brake is. It sure looks prettier though. I am sure if it was still done in Canada you would see more of it.
 
Brakes or porting increase the perceived noise level for the shooter. Anyone that says otherwise is full of sh+t. The only person that wouldn't notice the increase in blast is the person standing in front of the muzzle.

The downside of Magnaport is that it's permanent. There are a lot of effective brakes out there nowadays that can be removed. I'd always go that route if I were to get a brake..........which I never will.
 
I hate brakes or magnaporting... I have passed up buying beautiful guns because they were ported.
For a long range target gun sure. My 338 lapua had a brake which was made the recoil light but muzzle blast and noise was bad.

I have had 375h&h, 416 rigby and currently a 458 Lott with no brake or porting and they don t kick bad enough to need one.
 
I wouldn't pass up a good deal on a working rifle with Magnaporting.

I've owned two 375s with it and it really did a great job of reducing recoil and muzzle flip. Didn't find it much louder than w/o.

Neither would I . I picked up a Ruger M77 ( tang safety ) Tropical in 458 WM years ago . It had been magnaported by the previous owner . I do not like brakes of any sort , but I have to admit , the porting made the rifle far more controllable due to less muzzle jump . It was an amazingly accurate rifle by the way , I never should have sold it , but the needs of a young growing family always come first .
 
I have never owned a rifle with a muzzle brake, but shot next to a guy with a Model 700 in 416 with a barrel was ported.
Not a factory or after market one that screws on.
KI was sitting three benches over and could feel the concussion waves from that far away.
I could feel what appeared to be individual waves from each port on that rifle and it was Effin Loud !!!
And that was wearing ear muffs too.
Just my experience with muzzle brakes.

You definitely don't want to beside the muzzle of a big bore at a range, braked is worse as it is almost pointed at you and the range conditions make that worse as well.
 
My 338 WM Ruger Hawkeye has a factory muzzle brake. Muzzle blast is incredible as is the concussion wave which can be felt. Reduces felt recoil to 308 level however. I experimented with a medium burn rate powder to reduce the powder charge by about 20% and got a noticeable reduction in blast and concussion wave level.

But don't need the recoil reduction because 338 WM recoil with full on loads isn't much without the brake. Got a thread protector made and removed the brake.
 
I had one rifle, a beautiful Sako in .375H&H, sent to the states for Magnaporting back around 1980. I loved that rifle...but I sold it soon after it came back to me. The Magnaporting worked as well as any muzzle brake I have tried since in terms of reducing muzzle flip, and it didn't look like I had a corncob stuck on the end of my rifle the way brakes do. It didn't do a whole lot to reduce felt recoil on the shoulder. BUT...and this was why I sold it...and I don't care what Magnaport claims...and I don't care what the numbers show...the "perceived" muzzle blast/concussion was greatly increased. To me, that increased blast far outweighed any advantages I may have gained in less muzzle flip. I turned a gun that was pleasant to shoot into one that was unpleasant to shoot; lesson learned. Today, i see lots of rifles that appeal to me, but if they are Magna-ported (or, worse still, if they are braked) I won't even look twice at them.
