Or do you have to cut it shorter or rebarrel? Thanks.

The only way I know of is to cut the barrel, and re-crown! [Confused]

If I may ask, why do you want to get rid of the Magnaport? [Confused]

Obviously this is in regard to the 375 you posted about. Just shoot it and you'll appreciate the magnaports. They don't make a lot of noise like the muzzle brakes and it keeps the muzzle rise down.

Yes. The question is related to the rifle I am considering purchasing. I read on an earlier thread also that the magnaporting will diminish any collector value of the rifle. I don't know if that is true, or if the rifle collector value is significant. I am encouraged by your message that magnaporting is not too loud. I have read that the extremely loud report from recoil reduction systems are more and more disdained by PHs guides, gun clubs, etc. I really just want a shooter and not get fleeced in the process of procuring such. Thanks.

I would think any collector value the rifle had, is now gone with the barrel porting. I've passed on a couple of interesting guns because they were ported.

If you're considering this rifle and don't like the ports, add what it will cost to have a smith short'n and recrown the barrel to the price of the rifle. I dought the rifle will be as appealing [Frown]

gunther, just consider yourself fortunant that you are revieving $150 dollars worth of extras with the Maga-na-port already done! This system is no louder than the origenal, and does reduce the "FELT" recoil. The rifle has little collector value anyway, even as out of the box. Ruger No1s are only collector pieces if they are discontinued models, or chamberings. You will not live long enough for the 375 H&H Tropicle to be discontinued. Don't worry about it, and just enjoy shooting the rifle. The Maga-Na-port is a plus! [Roll Eyes]

I had a 300 weatherby one time( long ago) and my friend liked it so well he also bought one. The two were identical in every way down to the scope and rings. The stipled pattern on his Mcmillan stock was the only way to tell the two guns apart.

During the time I owned this rifle I decided to send it off to magnaport as I was suckered into the magnaport hype. When the gun came back my friend and I went to the shooting range together to site the rifles in and check things out before the fall hunting season.

The shock to realize there was zero difference in the two rifles was embarrasing to me. I just spent that money to have the work done and the shipping across country and I could not tell the difference in felt recoil by even a tiny amount.

The biggest difference was the blast of crap off the bench from those 4 slotted ports and the cloud of dust that blows into the air when shooting prone. It does reduce muzzle lift to a limited degree but as far as felt recoil is concerned there is nothing reduced with a rifle like a 300 weatherby.

Needless to say Magnaport did not make any sales with the guys who shot both our rifles. Most were stunned that the guns both shot and felt identical with the same loads using identical rifles. I would never buy that form of recoil reduction again! If I'm gonna ever get a muzzle brake( blast enhancer) I would go for the full on deal and just buy the best hearing protection money can buy.

I doubt there is anyway to fill in the slots and polish over them to make it invisible. Further the slots go into the rifling so any filler would have to be kept out of the barrel. The only way to solve this is to rebarrel the gun.

I would not hesitate to buy a magnaported rifle. It does not do anything bad to the gun or to the way it shoots. It just does Nothing at all from what I have seen using those two identical rifles.

JJ speaks with wisdom. Listen to him (if you still can).

JJ I'm a little puzzeled, what kind of Maga-Na-port did you get? The only one I've ever seen on a 375 H&H rifle was "TWO", not four, ports, one on either side of the front sight, and pointing "UP" at a 30 deg angle. Even if there were four ports, they would still be pointing "UP", not down toward the bench, With this said, my question to you is, how would gasses dirrected up, at a 30 degree angle make dust fly from under the barrel? Under the barrel is where I assume the bench is when you are shooting! [Wink] I had two 375 H&H No1 rifles, one not ported, and the other mag-na-ported, and the one that was ported was hard to tell from my No1 338, while the other 375 H&H was very different form the ported one! The reason I had the ported 375H&H was it was part of a multi rifle trade. The unported one was one I'd had for some time. I couldn't detect any more mussle blast noise with the Mag-na-port than the stock one either.

I'm not saying your experience with this porting is wrong, but what I am saying is it is "MIGHTY STRANGE", and diametriclly opposed to what I have experienced! Things that make you go HUMMMMMMMMMMMmmmmmmm! [Roll Eyes]

My rifle had four ports two per side and it was done by the "Magnaport company" Back east someplace I think in Michigan if my memory serves me right. Regardless of the location of the ports enough blast exited them to stir up whatever was around those slots. A 300 Weatherby is way over bore and provides plenty of gas!

I don't recall any additional noise issue at all, just that there was nothing done to improve the way the rifle worked or the felt recoil reduction. It was not just my opinion. There was often a few guys watching the muzzle rize of the two guns to see the difference in muzzle lift. reduced muzzle lift was detectable by everyone. Only a few inches but it was visible.

Identical felt recoil was also agreed upon by all who shot them both. I don't think Magnaport is "bad", I just don't see it as benificial on a rifle. I had it done to a .44 magnum uger Redhawk 7.5" barrel in the early 80's and the reduction in muzzle lift was significant, felt recoil was possibly a bit less with the big revolver, it had the same identical 4 port slot cuts the 300 weatherby had.

The muzzle lift and little bit of recoil reduction on the revolver was the reason I chose to have the 300 weatherby done the same way. The fellow at Magnaport told me(claimed) the higher the recoil the more reduction would be realized.

I also have a .44 mag Smith and Wesson Mountian gun(4" barrel ultra light weight), and bought another used gun identical as a gift for a friend who was dying to have one like mine. It was however already magnaported by the previous owner with the four slots cut through with the EDM machine just like the 300 wtby and the Ruger Redhawk were.

That gun realized the greatest difference in felt recoil and muzzle rise. With Garret 310 grain ammo out of the ultra light weight mountian revolver the muzzle lift is significant. The magnaorted version was about 1/2 the muzzle rise of the non ported version of the mountain gun. It also eliminated some of the twisting of the wrist when it recoiled.

I think for a very high recoiling handgun some small amount of recoil reduction can be felt and agreed upon by all users. Certainly muzzle rise is reduced which is probably enough reason to make it practical in some handguns.

However in a big rifle if you really want to reduce recoil don't waste your time with maganport. Go to the next level and get a real muzzle brake. If you get a real muzzle brake and decide you don't like it you can cap it off with a thread protector and be done with it. If you do like it, you can leave it and get some real functional value from it( Only with the best ear protection money can buy!)

With Magnaport if you realize it's not helping you your stuck with it forever and like the fellow in this thread, there is no way to remove it.

Mac, I went to the magnaport site and found this picture which is identical to the work they di on my guns.

JJ that shows you how long ago I had anything to do with Maganaport, or any type of recoil reducing device, other than a recoil pad! Mine were onlt the angled ones pointing up, and the side one were not on mine! I have one rifle, and one pistol, today with muzzle brakes on them. One is a TC contender 411JDJ, and the other is a Mauser 98 30-06 that had the brake on it when I got it for the action! [Confused]
