Ported Barrels

Post by t.r. »

My Savage 99 always had excessive muzzle jump which affected my shooting. So I did a little research and sent this .308 rifle to Magna Port in Michigan. Their skilled craftsmen formed four slots at the muzzle which reduced recoil and eliminated muzzle jump. Now I find this rifle a joy to shoot; it was money well spent. Cost to me was about $130.00 Disclaimer: I am not employed nor compensated by Magna Port in any way for endorsing their service.

For a time, Marlin ported their barrels with multiple round holes which is the same concept but different approach to eliminating muzzle jump.

Mag-Na-Port has long done excellent with, with commensurate results, using the EDM process to make internally-angled slots in thebarrel - and has been the Gold Standard in muzzle braking.

As you said, it's worth every cent to those who need some recoil perception/reduction.

It's too bad that some bubba's think they can achieve the same via drilling holes willy-nilly.

Hmm, we all pretty much know that porting reduces muzzle rise. But, it also increases noise. The OP mentioned Marlin's porting method, and you can see that Mag Na Port uses slots. I wonder if there is a difference in noise level between multiple small holes vs fewer slots.

I only have one ported firearm. A Ruger #1 I stumbled upon in a gunstore on consignment. $650 out the door, it had already been Mag-Na-Ported and had a Pachmeyr Decelerator pad professionally installed and came with a nice Leupold already mounted. Quite the deal! Of course that was back when I thought I needed a .300 Win Mag... To nice of a rifle to sell but I don't take it out much these days. Buddy of mine shot a coyote with it, to my knowledge that's all it's ever been hunted. All that to say between those ports and that soft butt pad it feels like shooting a .30-30, porting sure does help!

My M70 .308 Featherweight jumped up off the bench rest sandbags before it was Magna Ported.

I have recently noticed that the lack of muzzle rise helps stay on target after shooting at game. This recently helped me take two feral boars with two quick shots as I never lost the sight picture. Love it.

1st thing I did with my Marlin 1895GS was cut the porting off and make it a 16 1/4" nvm.

If I want less recoil I use my .22LR :D

Over the years I have noticed that used guns that are ported are harder to sell and bring less money when they do sell.

You may be correct, but no worries here mate!
My pre 64 M70 above will stay in my family as both my son and grandson want it.

My son already has my magnaported Ruger tang safety Mod 77 .338 Win mag, despite two good buddies bidding for it. :D

Porting not only makes a gun a lot louder, but will also pretty much make it a jacketed bullet only gun after porting. Those ports quickly fill with lead of you shoot lead bullets.

At 22 years of age and weighing 140 pounds, recoil sensitive, I decided to have my model 29 Smith Magnaported, which was a new company at the time in 1976.

It was an instant, easily noticed reduction in recoil. This revolver has since digested 4,879 rounds with 99% being cast bullets at around 1200-1400 fps.

I don't need magnaporting anymore as I have since learned there is much more pleasure in shooting handguns 800-1000 fps. :D

My experience has been no noticing of leading.

I did not notice any increase in sound with my magnaported .308 or .338.

Where I did see an increase in sound and sideways muzzle blast was with adding the muzzle brake on my daughters 7mm Weatherby Magnum. Blows dirt and papers off nearby benches at the range and makes no friends there either. Shot a deer once from a cedar tree blind and it defoliated several limbs and she could not hear for over an hour. She now removes the brake when hunting.

I was one time slightly behind CRS son when he took a nice blackbuck on a game ranch in Texas with the .308 caliber model 70. No, I didn't notice any difference in noise than with any other rifle in .308. In fact, I didn't realize it was ported.

The big thing with muzzle brakes is that the holes are angled away from the shooter. That helps to reduce felt recoil. I made a number of brakes that I tested on my Ruger Mk2 10". I finally settled on holes drilled 20° off , this setup has almost no muzzle rise. Yeah it's only a .22 but you would be surprised how much a .22 jumps around.

Porting is for shotgun barrels.
Porting or muzzle brakes make the noise change direction, it appears louder depending on where you are, have a roof over head.

The 1895GS? The noise was brutal, and no reduction in recoil that I could perceive compared to an 1895 Cowboy and 1886 EL.
The S&W 629PP, Power Port, factory ported, is a bit tamer to shoot compared to a few Ruger single action .44 mags I've had. It "might" be a bit less noisy, as well. YMMV :wink:
