Sunday Gunday: Remington 700 — History, Videos, Blueprinting

remington 700 bolt-action rifle gunday X-Ray Blueprinting

For today’s Sunday GunDay story, we look at the legendary Remington 700, perhaps the most popular American bolt-action rifle of all time. After covering the history of the Rem 700 rifle, we provide an inside look at the Rem 700 through a series of cutaway animations. Then we explain how gunsmiths can enhance a Remington 700 action through “blueprinting” procedures.

Remington 700 Origins and History

remington 700 manualAfter World War II, Remington Arms engineer Mike Walker began designing lower-cost alternatives to the Model 30, which resulted in the Model 721. These used a cylindrical receiver produced from cylindrical bar stock that could be turned on a lathe, rather than machined in a series of milling operations, which significantly reduced the cost of production. Further developments of the basic 721 action under the direction of Walker produced the Model 722 and Model 725, and ultimately in 1962, the Model 700.

Walker sought to increase the accuracy of the rifles, by utilizing tight tolerances in the chamber and bore, a short leade, and a very fast lock time. Like the earlier 721, the Remington 700 action was designed for mass production. Remington initially produced two variants of the Model 700, the ADL and BDL, in both long- and short-action versions. In 1969, Remington introduced upgrades for the rifle, including a longer rear bolt shroud, a jeweled bolt, and improved stock finishing. Four years later, production of left-handed Rem 700s began, to compete with the Savage Model 110, at that time the only major American-made left-bolt rifle.

Other Rem 700 versions include the titanium receiver 700ti, the 700 SPS (which replaced the ADL in 2005), and the CDL model. In addition to its development as a hunting rifle, the Model 700 also provided the basis for military and police sniper rifles, starting with the M40 rifle in 1966, which was initially ordered by the U.S. Marine Corps. The U.S. Army adopted the M24 Sniper Weapon System in 1986.

The Remington 700 is sold in both short action and long action variants. This photo is from the Big ED YouTube video comparing the two action lengths.

The Remington 700 is a manually-operated bolt action with two forward dual-opposed lugs. The bolt face is recessed, fully enclosing the base of the cartridge, The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body and bolt handle). The receiver is milled from round cross-section steel.

Chassis Systems for Remington 700s

With the popularity of the Remington 700 series rifles, and the availability of Rem 700 barreled actions by themselves, many companies have created after-market chassis systems. This Brownells Video reviews modern Accuracy Int’l chassis systems configured for Remington 700 barreled actions. Modular chassis systems have become particularly popular with PRS/NRL competitors.

Rem 700 Cutaway Video Shows Components + Operation

Ever wish you could look inside your rifle, to see how the trigger and fire-control system work? Well now that is possible with the magic of 3D computer graphics. Modern software allows detailed “cutaway” side-views (see below), as well as 3D views with 360° rotation. The software can also provide X-Ray-type views into the gun’s internals — as you can see above. And computer animation can show the complete firing process from trigger pull to chambering of the next round.

READERS — Do take the time to watch the video! This Rem 700 animation is really outstanding! EVERY bolt-action shooter should watch this video all the way through.

The Model 700 series of bolt-action rifles have been manufactured by Remington Arms since 1962. All are based on basically the same centerfire bolt action. They are typically sold with an internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are “blind” (no floor-plate). The Model 700 is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.

The Remington 700 is a manually-operated bolt action with forward, dual opposed lugs. It features “Cock On Opening”, meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin. A cam mechanism pushes the firing pin’s cocking piece backward. The bolt face is recessed, fully enclosing the base of the cartridge. The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body. and bolt handle). The receiver is milled from round cross-section steel.

Bill Marr Rifleshooter.com truing Remington Rem 700 action accurizingYou may have heard the phrase “blueprinting an action”, but do you know what that really means? Do you know what operations are done to an action during the blueprinting process? To help you understand, gunsmith Bill Marr of RifleShooter.com has created a helpful article showing a Rem 700 blueprinting job start to finish. This article spotlights how the procedures can be done with manual tools. Bill, who runs 782 Custom Gunworks Ltd., can also perform many of these operations with modern automated machinery. In fact, Bill has written a follow-up article on Truing a Rem 700 receiver with a Lathe.

Bill explains: “Blue-printing, or truing a rifle action, ensures the receiver face, threads, lugs, bolt lugs, and bolt face are square to the center line of the receiver.” In Bill’s informative article, Bill shows how he blueprints a Remington 700 short action receiver with .308 Win bolt face. He covers the following procedures step by step:

Action Disassembly
Ream Minor Diameter of Receiver Threads
Square the Receiver Lugs
Square the Face of the Receiver
Lap the Bolt Lugs
Square the Bolt Face

Bill employed a variety of tools from Brownells to complete the blueprinting job, including: Remington 700 Armorer’s Kit; Manson Receiver Accurizing Kit; Bolt Lapping Kit; Bolt Face Truing Tool; Manson Receiver Ring Facing Cutter; Multi-Vise with Jaw Pads; Silicone Carbide Abrasive; and Do-Drill Cutting Oil.

1. Truing the Receiver Face

Using the receiver facing tool, the front of the receiver is trued. The tool is placed over the tap and turned by hand. We used Do Drill to lubricate it.

2. Lapping the Lugs

The bolt lapping tool screws into the front of the action and applies rearward pressure on the bolt face. A little bit of lapping compound is placed on the front of the receiver lugs. The bolt handle is then raised and lowered repeatedly. Note — it is critical that we do not get any lapping compound on any other surfaces.

3. Truing the Bolt Face

On this bolt, the central part of the bolt face was low. After the truing operation, this Rem 700 bolt face is now completely square to the action.

Barrel Break-In Methods — What Top Experts Recommend

Barrel Breakin Break-in conditioning cleaning Wade Hull Shilen Walther Varminter.com Eric Mayer Video interview barrels

The question of barrel break-in is controversial. Some folks advocate an elaborate, lengthy cycle of shooting and brushing, repeated many times — one shot and clean, two shots and clean and so on. This, it is argued, helps barrels foul less and shoot more accurately. Others say minimal break-in, with patching and brushing after 10-15 rounds, is all you need. Still others contend that break-in procedures are a total waste of time and ammo — you should just load and shoot, and clean as you would normally.

We doubt if there will ever be real agreement among shooters concerning barrel break-in procedures. And one must remember that the appropriate break-in procedure might be quite different for a factory barrel vs. a custom hand-lapped barrel. This Editor has found that his very best custom barrels shot great right from the start, with no special break-in, other than wet patches at 5, 10, and 15 rounds. That said, I’ve seen some factory barrels that seemed to benefit from more elaborate break-in rituals.

What’s the best barrel break-in procedure? Well our friend Eric Mayer of Varminter.com decided to ask the experts. A while back Eric interviewed representatives of three leading barrel manufacturers: Krieger, Lothar-Walther, and Shilen. He recorded their responses on video. In order of appearance in the video, the three experts are:

Wade Hull, Shilen Barrels | Mike Hinrichs, Krieger Barrels | Woody Woodall, Lothar Walther

Eric Mayer of Varminter.com says: “That is a simple question, [but it] does not necessarily have a simple answer. Instead of me repeating my own beliefs, and practices, on breaking-in a new rifle barrel, I decided to answer this one a bit differently. While we were at the 2016 SHOT Show, we tracked down three of the biggest, and most popular, custom barrel makers in the world, and asked them what they recommend to anyone buying their barrels, and why they recommend those procedures. We asked the question, and let the camera run!” Launch the video above to hear the answers — some of which may surprise you.

Long-Term Barrel Care — More Experts Offer Opinions
Apart from the debate about barrel break-in, there is the bigger question of how should you clean and maintain a barrel during its useful life. Some folks like aggressive brushing, other shooters have had success with less invasive methods, using bore foam and wet patches for the most part. Different strokes for different folks, as they say. In reality, there may not be one solution for every barrel. Different fouling problems demand different solutions. For example, solvents that work well for copper may not be the best for hard carbon (and vice-versa).

Shooting Sports Lohman Barrel

Chip Lohman, former Editor of Shooting Sports USA Magazine, has authored an excellent article on barrel maintenance and cleaning: Let the BARREL Tell You — Match Barrel Care. In this article, Chip shares the knowledge of a dozen experts including respected barrel-makers Frank Green (Bartlein Barrels), John Krieger (Krieger Barrels), Dan Lilja (Lilja Barrels), and Tim North (Broughton Barrels).

“Why worry about a little barrel fouling when the throat is subjected to a brutal 5,600° F volcano at 55,000 PSI? To investigate these and other questions about taking care of a match barrel, we spoke with a dozen experts and share their knowledge in this first of a series of articles.

After listening to folks who shoot, build barrels or manufacture cleaning solvents for a living, we concluded that even the experts each have their own unique recommendations on how to care for a match barrel. But they all agree on one thing — the gun will tell you what it likes best. Because the life expectancy of a match barrel is about 1,500 to 2,500 rounds, the objectives of cleaning one should include: preserve accuracy, slow the erosion, and remove fouling — all without damaging the gun. This article doesn’t claim that one cleaning method is better than the next. Rather, we set out to interject a little science into the discussion and to share some lessons learned from experts in the field.” — Chip Lohman

John Nosler — Iconic Pioneer in Bullet Design

RIP John A. Nosler

John Nosler lived 97 years, passing in 2010. During his long lifetime, John was an iconic figure in the shooting and hunting world. Considered a true pioneer in bullet and ammunition design, Nosler developed the famous Partition bullet in the 1940s. Born on April 4, 1913 in Brawley, California, John built his business from scratch. He founded his bullet company in 1948. He was considered to be one of the great innovators whose designs helped create the premium bullet category and influenced ammunition manufacturers worldwide.

Moose-Hunt Inspires Partition Bullet Design
While hunting in Canada, John experienced a bullet failure on the hide of a mud-caked bull moose. He then began developing a revolutionary new projectile, which he called the “Partition”, because of the barrier that separated the bullet into two sections. One year later, John and a friend traveled back to British Columbia with his new Partition bullets, which were designed to provide deep penetration and expansion. The men bagged two moose with two shots, and the rest is history.

NRA Golden Bullseye Pioneer Award
In recognition of his contribution to the shooting sports industry, John was the unanimous choice for the inaugural 2007 NRA Golden Bullseye Pioneer Award. The award was the highlight of a long and fruitful career. Even though he officially retired in 1988 when his son and daughter-in-law, Bob and Joan Nosler purchased the company, John still managed to come to the office on a daily basis until his health declined.

Today, John’s son Bob Nosler still presides over the company as president and CEO of Nosler, Inc., based in Bend, Oregon. Along with bullets, the company now produces cartridge brass, loaded ammunition, and hunting rifles.

To learn more about John Nosler and his innovative bullet designs, get your hands on Going Ballistic, a “Professional Memoir” told by John Nosler to outdoor writer Gary Lewis. CLICK HERE to find the Going Ballistic book on Amazon. It is offered in paperback for $19.99 or hard-cover for $53.76. There is also a $6.99 Kindle edition.

John Nosler remained an avid hunter and shooter even late in life. Gary Lewis recalled that, at age 92, John Nosler attended the opening of a new shooting range outside Bend, Oregon. Even in his nineties, Nosler managed to drill two shots inside nine inches at 1000 yards. John Nosler leaves a legacy that will benefit hunters and shooters’ nationwide. The John A. Nosler Endowment of The NRA Foundation, sponsors the NRA’s Basic Rifle Training Program which instructs novices in safe rifle handling.
