Borden Timberline

The History of Borden Accuracy

Borden Accuracy was established by Jim Borden, who initially began as a silhouette and benchrest competitor in the mid-1970s, while also maintaining a role as an engineer for a Fortune 500 company. His interest in firearms expanded into the creation of his rifles, which then grew into a business of producing custom firearms for others in the early 1980s. Following his retirement from his previous engineering career in December 1994, Borden fully transitioned into the custom gun-building field.

Borden's dedication and skill have led to significant recognition. He set ten world records in the field, won 11 National Championships, and earned the Gold Precision Rifleman Award from the International Benchrest Shooters. In addition, he was an active participant in the leadership of the International Benchrest Shooters, serving multiple terms on the Executive Board.

Today, Borden Accuracy is a family-run operation. They operate primarily in the manufacturing of precision actions of the highest quality with the extremely low tolerances using CNC machinery. Their operational facilities are in the Springville, USA and are distributed across two buildings, comprising more than 6000 square feet dedicated to manufacturing and showroom areas. For practical rifle accuracy assessment, a 100-yard range with two covered solid concrete benches is maintained within the company premises. In addition to the high-precision actions, Borden Accuracy also includes custom rifle production in their operations. The product range consists of different categories – from hunting rifles, F-class rifles, and BR rifles to tube gun rifles. Each type allows for extensive modifications, enabling users to adjust specific elements according to the user’s preferences.

The brand is recognized for its extreme accuracy and reliability in both hunting and competitive fields. Their collective efforts have resulted in the manufacture of actions and the assembly of rifles that have won over 100 World Records and National Championships.

Borden Accuracy Timberline Rifle Review

The Borden Timberline is a name reserved for custom bolt-action rifles characterized by the long style (LA) actions with titanium body that are manufactured by Borden Accuracy. Unique to Borden's portfolio, the Timberline is designed to accommodate a range of magazine styles, from Single shot, Remington STD Magnum, and Remington Ultra Magnum, to Wyatt STD Magnum, and Wyatt Ultra Magnum. The action is 221 mm long and 34 mm in diameter, with weight variants of 595 g, 822 g, and 953 g.

On the front end of the bolt, there are two strong opposing locking lugs that lock up safely with the action’s housing. The Timberline is chambered for a variety of long action calibers and is available for both right and left-handed users. It features a two-position safety lever located on the upper right side of the receiver. On the opposite, right side, the bolt release lever is found.

For attachment purposes, the model is designed with four holes in the receiver, evenly distributed at the front and the back. The Borden Timberline is a highly customizable model allowing for a large choice of components such as the magazine style, weight, and the design of the action. This means that the overall specifications may vary from rifle to rifle.

Scope Mounts Interchangeable With Borden Accuracy Timberline

Rifles That Have One-Piece Scope Mounts Interchangeable With Borden Accuracy Timberline

For one-piece mounts to fit on a rifle, mounting surfaces on these rifles must match in every dimension.

Rifles That Have Two-Piece Scope Mounts Interchangeable With Borden Accuracy Timberline

To meet interchangeability conditions, two-piece mounts must match in all dimensions except the B distance. B distance can vary because two-piece mounts can be installed and adjusted closer or further apart.

Unfortunately, we were unable to find any rifles that would share the mounting dimensions with Borden Accuracy Timberline, thus we currently cannot provide you with the list of interchangeable scope mounts. Should you happen to own the rifle that uses Timberline action and would be willing to share with us more information regarding scope mounts interchangeability, please contact us at [email protected]

Your help is greatly appreciated.

Introduction

In recent years we can observe that a trend of Picatinny rail has become widespread and global. It is driven by the NATO standardized rails, more commonly known as the Picatinny rail standard. Picatinny rail being the New Jersey Arsenal that developed it in 1995.

These mounting options are revolutionary. The biggest and best advantage being that the Picatinny rail can be used its entire length and not bordered to a few pre-designed slots like for example the Weaver rail standard was before.

The other main advantage is the ease of use and interchangeability. If a product is meant for a Picatinny rail design it will fit all Picatinny-rails, no matter the manufacturer or date of production.

Picatinny/Weaver Rail

Picatinny Rail and Weaver rail profile

Design

The Picatinny rail is almost exclusively crafted from a single piece of metal (in some cases aluminum). In this manner, the axis of the Picatinny rail is perfectly straight and aligned with the axis of the firearm. Therefore the rifle scope which is mounted onto this kind of configuration is certainly aligned with the rifle / gun and the trajectory of the ammunition.

Weaver rail design on the other hand is usually manufactured in two separate pieces, greatly increasing the possibilities for the axis to be crooked, overlapping, and out of line.

It is always harder to align two separate pieces to a third line than it is to align one piece to another. In this way, the lapping of two mounting rings on a single-piece Picatinny rail is no longer required.

The single-piece rail will assure that both rings are perfectly aligned to each other and that no unwished stress is transferred to the riflescope.

Picatinny compare to Weaver Rail

The Picatinny rail itself is an evolutionary step forward from the older Weaver rail. The main difference between Picatinny rail and Weaver rail is the spacing of the slots. Picatinny rail design has them evenly placed exactly 5.23 mm from one slot to the other, 3 mm deep. For this reason, the mounting options are repeatable and the same as other firearms using the Picatinny rail standard.

Interchangeability was a major driving force in the development of the new standard as different NATO armies need to be compatible with each other.

Weaver rail has 3.8mm wide slots and these slots can be placed anywhere on the Weaver rail and in any number that the producer wished.

Advantages of Picatinny design

A big advantage for using the Picatinny rail design is the ever-present recoil stop. Furthermore, the manufacturing of the rail is not very technically demanding and can be done without the use of state-of-the-art machines which greatly reduces the cost of the finished product, making it very affordable.

The Picatinny rail is easy to mount and usually, this type of configuration does not transfer negative stresses and forces from the fired weapon to the rifle scope.

In addition, the Picatinny rail with its very long useable surface works well for mounting longer rifle scopes or to achieve optimum eye relief.

The durability and toughness are other big pluses for this solution.

Manufacturers of Popular Models

A majority of the Picatinny rings are fixed, but a number of best rated European manufacturers (EAW, MAK,..) have, in recent years, put a lot of effort into the development of detachable ring with100% repeatability, with which it becomes easy to remove the scope from the weapon without the use of tools.

No re-zeroing is needed with such mount options, but these models tend to be expensive.

Weaver and Picatinny Rings

Picatinny rail and weaver rail share one more thing. It is possible to use the Weaver ring and the Picatinny ring on the Picatinny-rails, but it is usually impossible to use the Picatinny ring on the Weaver base. The reason being the above-mentioned positioning and spacing of the slots.

Picatinny mounts have a 5mm recoil stop that goes into the rail slot and since
Weaver rail only has 3.8mm wide slots such rings do not fit on Weaver rails.

Due to this reason, the Picatinny-rails are popular and prevailing on the market in recent years and eventually, these options will completely oust the Weaver rail from the market.
