Remington 7400 Synthetic Carbine Impressions
« on: December 20, 2003, 01:29:00 PM »
:-)
I purchased a Remington 7400 Synthetic Carbine about 3 weeks ago to use deer hunting in the heavy foliage cover in central Minnesota. My previous use of a semi-automatic rifle has been the Ruger Deerfield, which is chambered for the 44 mag cartridge. This year the little .44 mag slug failed to get through fairly light brush cover. For this reason, I purchased the Remington 7400 in .30-06, a cartridge which can be loaded with a 220 grain bullet of good sectional density. This should penetrate brush a little better than the low sectional density .44 mag slug (I was using a 270 grain bullet).
I settled on the Remington 7400 based on my previous ownership of a Model 7400 rifle in .308. The Rem 7400  handles well for me when scoped, and I also like the balance for offhand shooting, the type of shooting I employ in my still hunting technique. The Carbine version has proven to handle well also, at least on the range and in some limited field carry. Price was also a consideration.
Upon opening the box, I was pleasantly surprised at Remington’s attention to packaging. In addition, there were no flaws in the rifle’s fit or finish upon initial inspection. I installed a Weaver single piece No. 93 base and used Weaver Quick Detachable split rings to install a Burris 2 ½ power Widefield  scope, one which has served me well for almost 20 years on various shotguns and rifles, most lately, the Deerfield.  I had some low power 220 grain .30-06 loadings on hand, these loaded to about 2200 fps with the Hornady RN bullet. I also had some Remington factory loaded 220 grain .30-06 cartridges. These went to the range. The scope came off for the initial sighting in of the iron sights at 50 yards. The sights are quite usable with the Weaver base left on the rifle receiver. 5 shots had the Remington loads grouping in the 6 inch bullseye, The scope was re-installed.  6 shots later I had the target out at 100 yards and the rifle sighted in. The weaker load shot about 3 inches under the Remington factory ammo at 100 yards with no windage variation. The weaker load would not cycle the action dependably. There were no cycling problems with the Remington factory ammo. Benched, hastily, both loads gave about 1.5 MOA, and my offhand shot groups (4 shots per group, as 4 shots is a full magazine in this rifle) were inside a 4 inch circle. This is good enough for me. I returned today with the Hornady 220 grain RN bullet over 51 grains of IMR 4350. Same point of impact at 100 yards as the Remington ammo. Additionally, the firearm cycles with this load.  Offhand I again got my 4 shots into a circle of about 4 inch diameter. The scope was removed, the irons tested at 50 with no need for adjustment using my 51 grs of IMR 4350 load, and the scope re-installed. The point of impact had not altered due to scope removal and re-installation. This is what I have found to be fairly true with the Weaver scope mount system.
So, in summary, the positives of this rifle/scope/mount combination are:
Good carrying, with my hand easily fitting around the receiver and scope at the carry balance point.
Good scoped offhand shootability, with the rifle coming to shoulder easily and on target, the balance of the firearm being such that offhand shooting is steadied.
 The only negatives in the entire set-up are:
The poor trigger on the rifle. It definitely limits decent offhand shooting to about 150 yards or so. The trigger pull is long and creepy.
The iron sights are very low on the rifle, causing me to have to crawl on the stock for fine aim. This is not of terrible significance, as these iron sights represent emergency sighting only. Were I to want decent non scope sights, I would buy the peep sights that fit on the scope base rails.
After reflecting on the rifle/mount/scope combination and the sixty or so shots I’ve fire through it, I would recommend this set-up to the woodland still hunter who was going to limit his shots to about 150 yards or so.

Hmmmm, I have thought about buying a 7400 Carbine in the pass for hunting in heavy cover.  I found your write-up of interest.  The Carbine would met 90% of my needs.  I might go for a 165 grain bullet for my part of the world.  Hunting partner shot a buck using 4895 pushing a 165 grain Speer bullet.  The bullet went though the top of an old pine stump, entered in front of the hip and came to a stop in the off side front shoulder.  About 50% of the bullet shank was recovered.

Without a doubt the round nose CorLock and the Hornaday bullets are excellant.  

Brother has a 742 and uses 4895 without functioning problems with 150/180 grain bullets.  Years ago he had a 742 in 280 Remington Caliber.  He had problems in that caliber with the slower burning 4350.  He no longer has any records regarding the load.  

Looking forward to future reports on your new rifle.

More Range Reports on 7400 synthetic carbine
« Reply #2 on: December 31, 2003, 05:00:40 AM »
Siskiyou,
After three more visits to the range, and an additional 70 or so shots, I can report that this rifle/mount/scope combination works well. It shoots where I point it at 100 yards, even after removing and reinstalling the scope. After six such reinstallation actions, the point of impact stayed within the same 4 inch circle at 100 yards from the offhand position. BTW, the trigger is improving with use, as the rifle has now had about 150 rounds through it. It is in no way going to become a good trigger as on my Winchester Model 70s, but it is now almost as good as the Ruger Deerfield trigger. The roughness is gone and the creep is still long, but it is now smooth. Also, not a single malfunction, and it has been cold, about 4 degrees F yesterday. I am using the 220 grain Remington Core Lokt factory and my 220 grain Hornady reloads (51 grs DuPont IMR 4350), both hitting the same point of impact at 100 yards.
Regards

Loads sound good, what more could you want.  Yearsago I installed a "trigger shoe" on my Rem 760.  It improved the feel of the trigger.  If you install a trigger shoe be sure and use lock tite on the screws.  Mine has never came lose, but I have heard of it happening.

I normally use heavy for the caliber bullets for full penetration.  In the 06' and the .300 Savage I use 165 grain bullets.  A friend goes heavier in his 06' in heavy cover because he is jump shoting bucks at close range.  There is little chance of the perfect shot in the rib cage.  I have been know to shot a couple of cedar trees in heavy cover.

More notes on the 7400
« Reply #4 on: January 01, 2004, 02:04:24 PM »
:grin:
Over the course of the last week, I have fired two strings of about 70 shots through the rifle without cleaning it. From a clean barrel, after about 30 - 40 shots the point of impact moves down about 1-2 inches at 100 yards and stays there. Clean it and the rifle is centered again for the next 30-40 rounds. This is in temperatures running from 4 degrees F to 24 degrees F.  This is not a criticism, just an observation. In fact, it shoots from a clean barrel to the same point of impact as it does for the next 30-40 shots. In a total of just over 200 rounds, I have had no failures to feed with full power ammo.
Also, the there has been no need to trim the brass after 5 reloadings.
So far, it appears that Remington gave me my $310 worth and more. Now to find one of those carry slings that needs no swivel attachments. Anyone know where to get these on the internet?

Looks like you will have that rifle well broke-in by next fall.  I suspect there are a bunch of older rifles around that have not had that many round fired through them.  Good for the rifle, and good for the shooter.

Sounds a bit chili there.  What kind of lube do you use on your rifles?

I can remember as a kid using three-in-one oil.  It would freeze the firing pin springs and they would not pop the primer.  Like everything else gun oils have changed over years.

7400 lubricant
« Reply #6 on: January 03, 2004, 07:08:55 AM »
Siskiyou,
I have not lubricated the rifle. I cleaned it after removing it from its shipping box, but have applied no lubricant. It appears that Remington has a graphite grease (light gray in color) on the bolt body. When I clean the bore, I also clean the chamber and the barrel extension slots for the bolt locking lugs using hoppe's No. 9. I now trust this rifle for field use.

Performance Update
« Reply #7 on: January 14, 2004, 03:54:22 AM »
Somewhere between 220 and 250 rounds the scope bases shot loose. Re-tightened, replaced scope and the gun was on. The hint had been the groups went up in size (to about 6 inches from 4 in offhand at 100 yards)and there was some vertical displacement. The trigger has improved signigicantly with use, so I have sighted the rifle in at 200 yards. Of interest, the trigger housing is a polymer. In about 290 shots there have been no malfunctions and the sustainable accuracy is commendable.

It sounds like you are having to much fun.  I nomally use loc-tite on my scope screws and a dab between the scope base(s) and the receiver.  My image of your part of the world is that it has snow on the ground this time of year.

Brother picked up a used 740 in 06 this last fall and has been practicing on digger squirrels.  Told me that he was going to load with 4895 the old 06 powder.  The price was such that he could afford to have a gunsmith refinsh the metal work.

740? There's some history
« Reply #9 on: January 14, 2004, 01:28:43 PM »
Siskiyou,
It is not too cold here, in fact it is warm for this time of year, lows in teens and highs in twenties. Snow has almost melted away over the last two weeks. Not even a lot of that here, upstate NY had much more of the white stuff. I imagine if you are at any altitude in northern CA, you could see similar temps this time of year.
Your brother got a 740. There's a piece of history. Those were changed to the 742 in early 60s.
I am having fun with this 7400. It has proven to be a much better rifle than I expected. It handles well, as I knew it would, but its accuracy and dependability are better than I expected. In this cold weather I use a graphite lube, and very little of that, on the hammer and lugs only.
Yes, I remember 3-1 oil, my mother had it for her Singer sewing machine, and it was a lousy outdoor lubricant, as my Mossberg semi-auto proved to me in the cold winters in central PA. Remember how it would heat up and smoke on a hot barrel/action in the summer? When I bought my first cleaning kit I got the Hoppe's Gun Oil, a much better lubricant, but it also had to be used sparingly in the cold weather. That little tube of black paste lube worked well if used sparingly in the winter. I still use that stuff, it is the graphite paste I refer to. It still is included in the Outer's or Hoppes cleaning kits.

Targetshooter:

Oops, I meant he had a 742, those brain cells from the 50's came out as 740.  Without a doubt altitude is a major factor in snow level this time of the year.  I-5 North and I-80 have been shut down a number of times because of snow this year.  

Without a doubt gun oil has improved over the years.

targshooter,

Wow!  $310 sounds like a real good price, was it new? They run about $400 around here.

such a deal
« Reply #12 on: January 17, 2004, 04:43:17 PM »
Yes, the store ran an incentive deal where they issued a store gift certificate. Otherwise they cost about $390-420 in this neck of the woods.
