Henry Rifle Forums

we are camped for the next couple of days north of Detroit in St Clair .... I spend most of the morning just south of our campground at Mag-na-port .... their staff is very friendly, helpful, and knowledgeable .... http://magnaport.com/ .... color me as being highly impressed .... I sent my first rifle (a Remington 700 BDL chambered for 300 WBY Mag) to them back in the early to mid '80's .... out of the box firing it was a brutal experience .... along with going to a top quality recoil bad and adding a Mercury Recoil Suppressor, having it Mag-na-ported turned it into a rifle that has been a pleasure to shoot .... based on our experience, Mag-na-porting provides several very positive factors :

1... depending on which process you pick, recoil reduction ranging from an average of 15% with our porting services up to 45% with our Mag-na-brake
2... our chronograph tests coupled with those from Mag-na-port that have been conducted over the years. It has been proven, time and again, that Mag-na-porting does not influence velocities to any meaningful extent
3... a dramatic reduction in muzzle jump makes it much easier to lock on for subsequent shots
4... no increase in muzzle blast or night blindness

more pictures taken, in their exceptional waiting area, will be shown in subsequent post

a series of pictures of the mounts on display in their waiting room .... as a most interesting fact, all animals were taken using a handgun ... .. the elephant is reported to have been taken by a 44 mag

a few of the very interesting handguns they have on display showing their process

That looks like a good time just sitting in the waiting room! Thanks for sharing tthos pics!

a few of the very interesting handguns they have on display showing their process ..... it most certainly is .... there are several other interesting, historic displays ....

semiautomatic pistols can also be Mag-na-ported .... the pictures below show a Sig that we had done today

shotgun ports are entirely different ... the ones below are in a Remington 11-87 barrel

Mag-na-porting our 45-70 is our last planned modification .... the insertion of a Mercury Recoil Suppressor in the stock cannot be seen and upgrading the recoil pad isn't readily .... the Mag-na-ported barrel can be seen below .... with us traveling I don't know when I'll get a chance to run some rounds through it but I'm sure looking forward to doing so .... over the years we have used this same combo of mods to several hard kicking rifles/shotguns and the results have been dramatic .... I don't see any reason that it won't really help this time as well

today I was able to spend several hours at a range belonging to a private club in southern Minnesota .... bottom line, I was delighted with the performance of both our Henry 45-70 and Remington 11-87 that were Mag-na-ported two days ago .... as noted earlier in this thread, my motivation to reduce the felt recoil of several of our rifles and shotguns stems from the fact I have to take blood thinners and will most likely have to do so from now on .... the result is I not only bruise easily but the bruising tends to run pretty deep and takes a while to heal .... unfortunately, a stout felt recoil is characteristic of the long guns I enjoy shooting the most .... today I fired 50 Cowboy Action rounds and 24 full power Dangerous Game loads through the 45-70 .... in addition, 10 rounds of 3" 12 ga 00-buckshot and 50 12 ga skeet shells .... no bruise, color me a happy camper ... ... we were firing at steel plates of various sizes at 100 yards ... shooting from a bench with 45-70 resting on two rolled up gun case, it took me several rounds to figure out that with the Cowboy Action loads I had to hold the cross hairs just off the plate at 5 - o'clock .... after that it became fairly routine to hit the 10 and 12 inch plates .... after switching to full power loads it quickly became obvious that the zero was very different .... with them the holding the cross hairs dead center of the 3" diameter plate consistently rang the bell ... at this point, that's close enough for me .... another observation, with the rifle resting on rolled up bags, the Mag-na-porting really shined .... holding the rifle with only my right hand, there was no muzzle jump whatsoever ..

Great pictures and story on your firearms' mods. I'd say that shooting 134 strong-recoil rounds with no bruises is a good reason to be a happy camper!! I've not done any porting to guns, but did add a very effective and helpful mercury recoil suppressor in the stock of my Benelli Nova 12-gauge. What a world of difference in taming recoil!

Glad you've had such good results to help you keep on shooting those bruiser firearms.

kind words appreciated .... no surprise on my part to hear that installing a Mercury Recoil suppressor helped .... from our use in a range of calibers for several decades I have come to regard it as proven technology

That's a great factory report. What a fascinating place to wait.

I'm really glad to hear what a difference it made to your guns. It seems to be well worth it.

Your Sig looks great!

the Sig isn't mine, it belongs to our oldest son .... it seem to be a nice pistol but I've never fired it .... those who know me will find it as no surprise that I'm and old school wheel gun fan ....

the first firearm I ever had Mag-na-ported was our Ruger Redhawk 44 Mag .... shortly thereafter we sent them our Remington 700 BDL chambered in 300 WBY Mag and our Remington 700 all weather 30-06 .....without doubt (prior to upgrading its OEM recoil pad, adding a Mercury Recoil Suppressor, and having it Mag-na-ported) the 300 WBY had the harshest recoil of any rifle I've ever fired .... it was brutal .... so much so that it took multiple sessions to sight in the scope .... our next candidate for recoil reduction is our early edition Ruger Red Label 12 ga .... its recoil is such that it simply isn't fun to shoot

Great post, would love to tour mag-na-port.

earlier today I took our recently Mag-na-ported 12 ga. Remington 11-87 to a sporting clays course and put it through its paces .... as already noted, being on blood thinning medication, reducing felt recoil has taken on a much higher priority for me .... most happy to report that 50 rounds later, no shoulder bruising ..

this coming Wednesday, on our way back home to NC from SD, I have a scheduled to meet 3 friends to spend the day shooting at Jay Henges State Park near St Louis .... weather permitting, I plan to fire a minimum of 100 rounds on their trap ranges (I really hope to fire 200) .... in addition, I hope to fire 50-100 cowboy action level rounds through our Mag-na-ported 45-70 .... last year rain prevented us from shooting while we were there, thankfully no rain in the forecast this year but they are calling for 90+ degrees

I have a Taurus Raging Bull in .454Casull that was ported at the factory.
I'm not sure if it is "Magna-port", but the porting makes a huge difference.
My Raging Bull has an 8-3/8" barrel and a full under-lug, so there's quite a bit of heft hanging out there, but I think the porting makes the most difference.
That pistol pushes straight back down the line of your wrist. Absolutely zero muzzle rise.
Reacquiring a target is almost second nature.
Really love that gun.

all porting redirects muzzle some blast .... while it is very effective, I don't care for the porting that directs any of the muzzle blast back into the face of the shooter .... the first one I can remember was the old Browning Boss system .... those, I will not fire .... while I don't believe Taurus uses Mag-na-porting, their system looks to be very similar and is one I would be happy to use .... classic Mag-na-porting and Taurus both redirect the force of the force from the blast in directions that ways that stabilize the muzzle .... its a concept that I'm sold on

I was wondering about that muzzle blast. Seems to me the more it blows back the more effective it would be at reducing felt recoil.
