Author Topic: Remington 750 Improvements over Model 7400 (Read 16170 times)

Forum Shooters,
Remington is kind of quiet on listing the actual improvements that the new Model 750 offers over the 7400. Remington offers vague references to an improved gas system, better balance, etc. Can any of you detail the changes? Is the gas system more easily field stripped for cleaning? Is the over all quality (such as wood to metal fit) of the rifle improved over the 7400? Does this firearm offer competition to the Browning BAR? It seems that the rifle is accurate enough, as is my 7400 Carbine, but I for one would like to see some quality improvements in the above areas over the 7400 before I commit to a 750.
Regards,
Targshooter

Good question!!!!!!! There must be someone out there that has the answer. I'd like to know too. However it's to late for me as I already have a new 750 in.308 with a Leupold 1-1/2-5 VXIII. Shoots just over an inch consistently.

Targshooter;
Hi there. I have a magazine, Gun Buyers Annual #39, which contains an article on the M750. In part it reads, "Remington moved the gas orifice holes rearward about 0.75 of an inch and redesigned the barrel lug to reduce the orifice hole size for improved bolt velocities, for a more improved operating mechanism". Quote unquote. Further more, the article shows several pictures of the M750, one clearly shows the engraving on the receiver....'Remington WOODMASTER Serial No. D8000013'. No, I did not spell it wrong, it reads WOODMASTER. The rest of the article calls it a woodsmaster. I do not own any Remngton firearms and always liked the looks of the Model 7400. I have never fired one so cannot comment on reliability. I do find it worrysome that Remington couldn't get the name right for the article. What else is not right? I posted a previous article about this, "Whats in a name". Perhaps this should be on the Remington Forum.

Best Regards
BC

32WINSPL,
You do have to wonder. "Woodmaster" would be a good name for a chainsaw. I believe Remington did have their name on such for a while. Perhaps there is corporate confusion.
That article at least does detail some of the changes. Apparently there have been no radical changes from the 7400 to the 750 insofar as the process of field stripping and cleaning the firearm is concerned.
Thanks

I have put about 120 reloads through my 750 35 whelen with no failures to function. Does not seem to be sensitive to cleaning, but it's been warm out. Wood fit is very good on mine. Trigger is my biggest complaint, but do not have enough nerve to work on until after hunting season, ( only 51 days away!)
Friday it is going to get s serious workout at the range with the chronograph.

targshooter i cant compare as i never owned the 7400 but i do have a new 750 in 35Whelen and i can say the looks and feel of the rifle is what made me buy it. For me it points like it was made for me the wide forend is what i like in a rifle as i have big hands . I am now working on finding a good handload for the hunting season but the remington fgactory 250 grain bullets shoot just fine. My first trip to the range i put on a 3x9 ziess which to me through off the balance i wasn't happy with it was very uncomfortable with it but i still got 1 1/2" groups at 100 yds. I now put on a leupold vari-x II 2x7x32 and what a difference to me in balance i am sure i can close that group to an inch if not under. I am very happy with it . Its also very easy to give a through cleaning. I prefer this rifle over the Browning BAR which i had for several years in 338.

tanoose,
I have a 7400, and to clean the action thoroughly you must remove the barrel, something I am not going to attempt, as the rifle is very accurate and I am afraid that my tinkering with it may remove this edge in performance. The Browning allows a fairly thorough cleaning without removing the barrel. Does the new 750 also permit this? I am also very impressed with the 750's handling qualities, and it is for this reason that I am curious about its ease of field maintenance, as I have looked at the 750 in .35 Whelen withmore than a passing interest. Thanks for any information you may share.

tanoose · « **Reply #7 on:** July 23, 2006, 05:19:35 AM »

Wow i wasn't aware that you had to remove the barrel on the 7400 and i am not sure how to remove the bolt on the 750 i will be with a friend tomorrow who is a gunsmith and will find out it would make sence that the entire bolt comes out in case you need to field stip the gun . The way it is in the receiver you can get to about 95%of the bolt ,you just cant get to the top part of the bolt that slides on the receiver. The bolt handle and the slide bar have pins and i am thinking the removel of these pins will allow the removal of the bolt , i will find out for sure tomorrow or tuesday and let you know. If the bolt cannot be removed there must be a way to clean the top of the bolt inside the receiver . (i hope) I am going to give this a good look over this afternoon and get back to you in a couple of days.

Well Targs its like you said alot of work to get the bolt out however i was told that there would never be a need to take the bolt out as the only part you cant get to is the very top of the bolt that runs along the top of the receiver , i was told that and not needed every time you shoot to use a pressurized can of cleaner that is synthetic based . Rem clean and another called gun scrubber were mentioned . I was told all you had to do was spray the area that was fouled and run the slide back and forth a few times and this will get everything out . But you also must then use a light coat of oil to the area and any parts that was hit with the spray as it works like carb cleaner and it takes off everything including all oil. Take out the trigger assembly before spraying the bolt. I was told the 750 would not get fouled like the 7400 due to the improvements made to the rifle . The improvements made you can find at the Remington website under questions and answers.

I found the post on Remington.com for anybody esle interested.

Here's the link to the question on Remington's website:
7400 vs 750

Question:What are the differences between the 750 and the 7400?

Answer: In the 750, the gas orifice hole is drilled at a 45 degree angle, instead of a 90 degree like the 740/742/7400. This does 2 things; it eliminates the 90 degree turn at the gas port, and it eliminates shaving off copper in the bore from the projectile. The copper shavings in the gas port of the 7400 would build up over time, and cause the gun to not cycle reliably.

The gasblock on the barrel has been moved rearward and therefore the gas orifice hole has been moved rearward. Moving the gas hole back we can capture the gases sooner, and under greater pressure. This will greatly increase reliability by giving more consistent bolt velocities, as well as allow us to offer carbine models in calibers not possible in the 7400.

The barrel extension is now made as a cast part instead of a machined part. By casting, we can better control internal geometries, and eliminate machining burrs. This, again, translates into better reliability.

We have added a nickel/Teflon coating to the bolt head. This allows the bolt to move and cam into place more freely.

Since the gas system is greatly improved, we can now use the R3 pad, and not have to worry about functionality.

We lowered the drop at the comb so that you can use the rifle sights easily.

Thanks Gents,
Some great answers and references. Finally understand why I can get my eye on the iron sights on the 750 in the store. I cannot crawl around on the stock quick enough for a snap shot with irons on the 7400.

NYH1 · « **Reply #11 on:** July 28, 2006, 02:06:55 PM »

I might have to get a model 750. I know I'd get a carbine, just don't know if I'd get the 308 Win. or the 30-06!

nrb · « **Reply #12 on:** July 29, 2006, 12:31:13 AM »

The comment was made that the barrel of a 7400 must be removed in order to clean it properly. This is not the case. I have used a 742, 7400, and 750 for many years and find no problem with cleaning a 7400. Just open the action and use a chamber brush and a nylon pull through brush or patch with appropriate cleaning solution. To clean the action, remove the trigger unit pins, remove the trigger unit and clean the inside of the action and trigger unit with glee. These are fine rifles.
best, nrb

New York Hunter if you use 150 grain bullets then the 308 might be the better choice but if you like the 180's then with the short carbine barrel the 30/06 would now give you closer to 308 velocitys while the 308 carbine might give you closer to 300 savage velocitys . just something to think about.

Well I really like the 308 Win. I have a pre-'64 Winchester model 88 that I've shot two deer with. I use Remington's 150 gr Core-Lokt ammo in it. I was thinking that the 30-06 with an 18 1/2 inch barrel would be pretty close to a 308 Win. with a 22 inch barrel performance wise. Like I said though, I really like the 308 Win. so I still don't know what I want to do!

New York Hunter if you hand load you may want to stick with the .308 the handloader can not only duplicate but can achieve higher velocitys in the 308 with 150 grain bullets but he cannot with the heaiver bullets . But to be honest for deer and blackbears there not going to know the difference between the 308 and the 06 and its nice having the same ammo for two different rifles. Good luck with your choice

tanoose, No I don't hand load. I probably won't buy one for this coming season so I have time to think about it. Thanks!

I've got the 7400 in .308. I had a flap of barrel steel (rifling) block the port hole in the barrel. I spoke to a gunsmith and he recommended the proper drill to clear it. But I noticed the drill would bind and I thought it was clear. This piece of steel would move back and forth as on a hinge. However at the range the flap repositioned itself over the hole and no action. This time took an awl and popped it out. No problem. There is no piston or rod to operate the bolt. I noticed the lower forearm stock is lined with a metal plate to contain the blast blow back from the port which has a right angle fitting pointed rear. At the end of the rails theres a plate (cup) which acts as the collecter and blows back to operate the action. I think there's some waste of power in the system. I was told this design would cover a range of loads and bullet weights...?? I had cycling problems when using 120gr bullets but no problems with 150 to 180gr. Also with the port hole blocked I was on target shooting as a single shot, but strangly enough with the port cleared I was 1 1/2 inches low at 100 yards. Power loss to operate the action..??

I am delighted to find this conversation about the new 750 Remington. I am considering a new 750 in 35 Whelen. My other option is to spend nearly $500 for a rebarrel of my old Ruger M77.

My Remington 742 is one of my favorite rifles for feel and handling. It is far better than any bolt rifle and equals the Lever Guns in handling. The trigger was stiff when newer, but I have worn it into submission.

I have had two 742s in 30-06. If I had the option to buy them new, I would probably have gone for a 308 Winchester instead of the 30-06. However, both of them shot great. My first one was used only with jacketed 150 and 168 grain bullets and 1.5" was pretty much standard group from the bench.

Number 2 rifle has to date shot 2311 cast bullets. I cleaned it the first time at 1400 rounds and I only cleaned it them because the bolt froze shut from gunk and grit after it got cold. The gas port has never plugged up. I use 25 grains of Reloader 7 with two different bullets. Saeco molds # 315 (173 grains) and #301 (200 grains). The velocity with the 200 grain bullet is 2017 fps and 1811 with the 173 grainer. I have used 35 grains of Rel 7 with the 200 grainer and chronographed at 2176 fps. The accuracy with this rifle is simply incredible and it simply blows people's minds when they see it shoot. If I play the wind and mirage properly, I frequently hit the steel Ram at 500 meters. It doesn't always knock the 55 pound steel critter over, but eventually, I get it with follow up shots and rattle it off. I am shooting a Ruger #1 in 35 Whelen and 250 cast bullets. The Whelen will take the Rams down on one shot most of the time. It is bullet weight and momentum that takes the Rams down.

So, you can see why I'm thrilled and interested in the 750 in 35 Whelen. One of my main reasons is the reduced recoil in the Remington 742s and 750s. I will be shooting 200 and 250 grain cast bullets in it too.

Cleaning: The first time I cleaned it was hopefully the last time I would ever clean it. I had a more mechanical friend come over and we tore into it. It was not fun. Of course, I hate cleaning any guns. I was however, able to get most of the beast cleaned and the parts that I couldn't get to come apart, I used Gun Scrubber spray and then sprayed Rem Oil into all crevices. I declared it cleaned to the best of my ability.

I would be interested in hearing from anyone's new experiences with the 750 in any cartridge.

Harold

I just picked up my 750 carbine in .35 Whelen, but can't get out to play with it for a few days

.

Talk about frustration!!!
