Magnaport? Compensated?

[mechanic]

What is the difference in magnaporting, and compensating?  Is there one really?

magnaport is a trade name for
a process of edm machining compensating ports


if that's what you wanted to know. . . .

[Ranger99]

if you're thinking about porting something,
i'd recommend you fire a similar ported
something first to see if you can bear it.
i wish i had.
way louder (to me)
not that much recoil help (to me)

Sounds right, and confirms what I thought I knew...    A friend was telling me if I put a compensator on one of my rifles it would take away 90% of the recoil.  I showed him my 280 which has an after market compensator, and said it was just magnaported.....Sometimes I'm afraid to come down too hard on a point I'm not totally sure of...
 
Thanks,

i'll admit right off that i'm sure not
the smartest dude in the bunch, but
i've yet to see or hear tell of or fire
a gun with a device that would shed
90% of the recoil.


wouldn't that be nice?

i've got one ported something and
it does cut muzzle flip , but if anything
it shoves backward that much harder.


if i could figure a way to skirt newton's
law ,i'd be a gazzillionaire

They both are gas redirecting devices designed to ameliorate recoil.. The magnaport must stay within the physical size limits of the barrel. A muzzle brake on the other hand is larger physically allowing a larger expansion chamber and more effective port profiles.. But the device is quite a bit larger.. I dislike them all but would use one if recoil reduction were mandatory for me. Bad shoulders or backs can make us all do whatever is needed to keep shooting..

I agree...Mag-Na-Port controls Muzzle rise and changes the recoil impulse a bit...15% I've read.  I believe this works as advertised...I had it on a 300win mag (which got re barreled and not re-ported) and I have it on a lite Rem BDL in 375HH mag and I DO believe it helps with both.

My 280 has a ported barrel, I bought it that way, and a friend was trying to tell me a compensator was different and better, etc.  If his claims of recoil reduction were true, every heavy kicker would be that way.
 
I know it makes it louder, esp. in close places.  The range here has a roof over it, and you had better have good ear protection.
 
As for recoil reduction, the 280 ain't that bad anyway, but it's probably more than I will be able to do.

Long ago I had a 14" .35 Remingto TC barrel. I sent it to JD Jones at SSK Industries and he rechambered it to his .358 JDJ. It would push 225s at 2300 fps with one grain less than SSK's max using AA2520.

That thing came off the sandbags about to a 45% angle and twisted so badly my wrist just couldn't take it.

I sent it back and JD put his arrestor brake on it. Afterward it did not lift off the bags or twist any at all. BUT all that force was redirected into the web of my right hand. Problem with that is I have a bone spur or calcium deposit or some thing of the sort. I can't shoot loads equal to .44 magnum level without using rubber grips and even then it eventually gets to me. It hurt so bad to shoot it with the recoil all coming straight back into my hand I just gave up on the barrel and sold it.

That's what compensators do. The just redirect the recoil in a more straight back manner and take away any or at least most of the barrel rise. If it's a revolver that's ported I can't tell any difference in noise but on other guns it is WAY more noisy to the ears.

I had a 6" .45 acp that was magnaported. I had the magnaport section cut off and a compensator put on.  The compensator reduced muzzle climb much more and much more than doubled the recoil reduction. Remember, each will increase the sound perceived by the shooter, on a rifle the comp will do much more. Also, with a compensator on a rifle. you will not be very welcome on a common firing line.

Just remember,,there's no free lunch. The better the brake at redirecting gas toward the rear to reduce the recoil punch the louder they get and the bigger! The huge brakes on some rifles that appear flat with two ports (on each side) pointing 45* to the rear with the huge chambers work extremely well but all require large cased rounds and high pressures to do their best work. They provide large amounts of gas for the ports to redirect and the higher the muzzle pressures of those gases provide more thrust. The problem is those rounds also develope more recoil that needs countering. I believe a more moderate round in a well designed rifle with design changes to allow more comfort will provide a better answer.. Recoil pas, recoil arrestors, wide butts and easy gripping surfaces on forearms can provide help as well as such things as butt plate angles,, As always your best friend is weight.. It slows the rifle and thus spreads the recoil over a longer time period..

I have some compensated Contender pistol barrels that make no friends on the range.  It isn't just the rifles!
