Welcome to the forum. More hype than anything else. I have seen no difference in accuracy. Its more important to have quality bedding and a good quality barrel...my two cents.

Don't mess with old guys. they are too old to fight, too fat to run, so their only choice is to kill you.

You can't fix STUPID, but you can vote it OUT !!!!

Remington 5R is a bolt-action rifle.


Its a limited production, specialty variant of the famous 700. I've never owned nor shot one, but you can read a bit about them here:

russ735,

Welcome to the GunBroker Forums!

I've shot several of these and overall, they have been better than decently accurate when proper ammunition is used.

Two simple points:

1) The term '5R' is a reference to the style of rifling originally developed by Boots Obermeyer. The sides of the lands are angled slightly with smooth transitions between surfaces.

2) The term 'Mil-Spec' is more often misused than used correctly, especially when it comes to advertising a product to civilian wannabes.

Boots Obermeyer, Mike Rock and Gary Schneider have all manufactured barrels for military contracts. I think Mike is the only of the three that no longer has a contract currently.

The 5R rifling style is easier on the bullet jacket which can translate into better accuracy but in the real world usually means more consistent groups. This rifling style helps seal the barrel interior better, preventing blow-by of the hot gases around the bullet. The original runs of 5R Remingtons have a reputation for being excellent in the accuracy department. That blog mentioned above has some illustrations of this in one of the sections. That's about the only thing that is useful from that link since the author doesn't know squat about barrels, rifling or ballistics. At least he can shoot.

This is from a Remington employee and may show a little prejudice:

"Let me as a Remington employee, and owner of a 5R clarify a few things for you. I know for fact that the barrels on the 5R are not rock's barrels the first few for the military contract M24 sniper rifles were, until we could tool up or equipment to produce our own R5 rifling. The barrels are not military barrels that did not pass our quality checks either, any barrels that we produce that are not exactly to tolerance are immediately marked with red Dykum and sent to the barrel bender. The gun however is a limited production non-cataloged 1/4MOA firearm. And unless you want to pay for a M24 about $3.5K and get a gun that shoots just the same as a 5R. Now for all of you who think that the 5R is just another factory produced gun with a marketing plan you got another thing coming, now the R5 is not a custom gun but we put a lot of pride and tradition into each firearm we produce and the R5 is no exception in the least. I have time and again at local matches put them $5k customs to shame, and I guarantee you that the difference between a 700 Sendaro and an R5 is quite astounding. Or you could just come up to Ilion and find out the hard way. So in closing boys and girls the R5 is a very exceptional weapon that i would put up against any custom out there."

I would buy one of these unless I wanted to afford a custom which I can guarantee will perform better in the long run.

Best.

Thanks Guys. Yes, this is a 700 S.S. A friend has one in .308 and it is a very good shooter. The funny thing about it is it will shoot just about anything well. I'm talking 1/4 moa with some and nothing worse than 3/4. I just picked up one in .223 and have high hopes for it too.

I just got back from breaking in my .223. It seems to shoot well if the bore is clean. Try to string more than 3 shots and look out. The first three will be in the same rough hole four and five could be an inch away. Nosler brass, 69gr. smk 24.5gr varget cci br-4 primers.
Only ran 20 through her. May be a little heavy of a bullet for 1 in 9 twist

russ735,

Split groupings are usually not attributable to a dirty barrel. Rarely will a barrel foul significantly within 3 shots either, unless something is dramatically wrong.

3/2's or split groups are usually a matter of a lack of bedding or free-floating the barrel. Remington's idea of a pressure point at the end of the forearm has presented many shooters with a problem over the years. This is a simple fix of sanding down the pressure point and continuing with your testing.

However, many times we have found that the barreled action isn't proper seated and stress-free or that it's not in the center of the action/barrel channel. The proper fix is to have the barreled action pillar bedded and the barrel free-floated as good as can be achieved given the stock material.

There are other problem/solutions but this is the place to start.

Now, as to the 5R rifling, here is a short excerpt from a previous article which I found in my notes:

"The rifle derives its name from its barrel. 5-R Milspec refers to the rifling used. 5R-rifling features a radius'd shoulder between the lands and the grooves. Advantages are claimed to be a smoother engraving transition on the bullet jacket which, in theory at least, creates less drag in flight - which means possibly a slightly flatter shooting bullet compared to a bore of standard rifling profile. The second benefit is cleaning. Without the 90-degree angles between lands and grooves, fouling seems less likely to adhere as tenaciously to the bore. Copper fouling may also be reduced. This rifling profile is used in the Army's M24 Sniper rifle. It has a proven track record for accuracy at long range, often making M.O.A. or better shots possible to 1000 yards. The M700SS 5R Milspec has a 24" stainless steel barrel very close in profile to the original 700P Police rifle, before Remington went to the longer 26" tubes on their police line."

From John Krieger's website:

Traditional 4-Groove rifling form



5R or Transitional Rifling (5-groove)



T/C 5R rifling diagram



There are lots of speculations regarding the development of the 5R rifling form and the internet has been responsible for the loss of much of the truth regarding this and so many other subjects. I have used a couple of HUNDRED of these barrel in the last year so I have intimate experience with this type of rifling and the barrels. I can tell you for a fact that the 5R style reduces the stress on the bullet jacket and is easier to clean in general. There is also a better seal between the barrel interior and the bullet jacket.

This is not my set of targets but an illustration of the 5R Transitional barrel in the field:



These targets were shot with a .260 Rem in a custom rifle using a Bartlein 5R Transitional Twist barrel.

Best.
