Internal Hook Extractor

internal hook extractor

I had previously shared a picture of the Internal Hook extractor installed in one of our coned single shot bolts that we use for the bottom eject Rimrock Benchrest actions.  The above picture is of the internal hook extractor installed in a Borden Timberline Magnum bolt. We are now offering that extractor on bolts that have the repeater nose in 308 and magnum bolt faces.  the extractor does not require any machining of slots in the outside surface of the bolt.  The extractor becomes of better option for those not wanting the Sako style extractor as it keeps ejection angle low and also minimizes the machining of the outside surfaces of the bolt body.

Alpine, Timberline, Ridgeline, Rimrock SSR, Rimrock LSR, Mountaineer models can all be ordered with the internal hook extractor for 308 and magnum bolt faces effective immediately.

Introducing The Borden Rimrock BRLXD and the Borden Ridgeline actions

The Rimrock BRLXD

BRLXD Right

BRLXD Front

BRLXD Right2016 has been an exciting year of development at Borden Rifles.  The introduction of the Borden Rimrock BRMXD action in January was a success and the demand for that action also created a demand for a longer version of the larger diameter action.  We are now producing the Rimrock BRLXD version of our BRL action.  It is 1.470 in diameter. It is available with 30-06 and standard magnum boltfaces.  It is available RBRP; RBLP, RBLPRE (for 284 and 30-06 length cartridges); RBLPBE (for up to 284 Win length cases).  We are also offering the LH versions of the same combos.

Borden Ridgeline

Ridgeline left

Alpine Ridgline Timberline

Getting the right fit in an action for mid length cartridges has been a challenge for years. Many cartridges like the 257 Roberts, 6.5×55 Mauser, 6MM Remington, 284 Win, 6.5×284 Win and the WSM and RSAUM cartridges have been put in the standard short action which restricts overall length of the cartridge and effects its efficiency. Those same cartridges when done in standard long action result in excess space in the magazine well. For that reason we have introduced the Ridgeline series of actions which feature an opening of 3.2 inches in the magazine box. These images show the three lengths of action: Alpine Magnum, Ridgeline and Timberline Magnum. McMillan will be inletting stock patterns that accept either Short or Long Remington actions for the Borden Ridgeline.

The Ridgeline is offered as repeater or Single shot and can be bought as a Titanium version as well.  We have “Standard” mag boxes as well as WSM/RSAUM mag boxes available for them. Also, the Obendorf style drop floorplate trigger guard systems are expected to be here soon.

New Rimrock BRM Multi Flat action-BRMMF

img_1925

We are taking orders for the New Rimrock BRMMF action.  Its is round on bottom (radius .735 inches) and it is 1.4 inches across flats.  The RBRP version with screw on bottom lug weighs 40 1/2 ounces.  It is available RBRP, RBLP, RBLPRE, RBLPBE, LBLP, LBRP, LBRPLE, LBRPBE.  Action body is 416 Stainless hardened to 40 to 41 Rc, teh bolt body is 4140 chrome moly hardened to 43 to 44 Rc.  The bolt shroud, bolt stop and bolt handle are all stainless steel.  the trigger hanger is aluminum. It si available 308 boltface, magnum boltface and the bottom eject also offers a PPC boltface.  The stand ejection uses 308 boltface for PPC.

non dual port actions are $1325 plus $75 for bolt on lug. Dual port actions are $1400 plus $75 for bolt on lug.  We will have Dovetail bases and pic rails available soon.

Borden Alpine Magnum Titanium Action

Here are some pictures of the Borden Alpine Magnum Ti action finished with the exception of the PVD treatment. The unit as shown here weighs 19.36 ounces.

After considerable discussion with three gunsmiths today I have somewhat softened my position on selling them without PVD treatment. The action cycles nicely but it does not feel the same as 40Rc EDM cut 416SS. I am finding that is not important to everyone. So, I will offer them 3 ways. Here are the prices (taking into consideration the current cost of Grade 5 Ti hardened):
Prices are for the Ti action with chrome moly bolt with deep spiral flutes, SS handle; SS bolt stop, dual pinned SS recoil lug and fluted aluminum shroud.

Short action with no PVD-$1600.00
Long action with No PVD-$1650.00
Short action with PVD treated bolt-$1680.00
Long action with PVD treated bolt-$1730.00
Short action PVD treated action body, shroud,bolt stop, recoil lug,bolt body–$1900.00
prices are for the Ti action with chrome moly bolt with deep spiral flutes, SS handle; SS bolt stop, dual pinned SS recoil lug and fluted aluminum shroud.

Ti Alpine

Ti action side view

Ridgeline and Titanium actions will soon be introduced

We have an Alpine Magnum action made in Titanium ready to send out to be PVD treated.  The action looks good and I am sure will be a hit.  Right now introductory pricing will be $1900.0 for Alpine and Alpine Magnum in Ti and $1995.00 for Timberline and Timberline Magnum in Ti.  Current delivery is about 20 weeks and we will commence taking orders about 11/21/16.  We plan to test fire the prototype after PVD treatment to test for reliable function and cycling prior to accepting any orders.

We have finally located a supplier willing to make the magazine boxes for the Ridgeline actions. we are hoping the test boxes arrive soon along with the custom Obendorf style drop floor plates.  The actions will be sold complete with the bottom metal.  Keep watch here for updates.

New Product—Borden Rimrock BRM Right Bolt left Port Bottom eject

Borden Rimrock BRM Right Bolt Left Port receiver with bottom ejection port

_81A7487

Please excuse the fact that I failed to clean the dust and grease from the bolt prior to taking the picture of the bolt nose and extractor 🙂

_81A7490At the continued encouragement of Greg Taylor and Alex Wheeler we have developed a bottom eject model receiver for our BRM and BRMXD line of actions.  the hold up has been having a suitable extractor.  We did not wish to use a Remington style extractor due to the flat combined with coned nose on bolt that would make the model have a unique breaching system from our other actions. For many years I have been interested in using a internal hook extractor that does not require breaching the outer diameter of the bolt nose. the one we have developed is not unique to us but it has been difficult to find a screw machine shop willing to produce it. So, we decided to produce them here on our Hardinge CNC Chucker–not a very efficient way to make them-but a necessary way in order to get them made to make this model available. One of the key advantages to the bottom eject model is that it eliminates the need for a plunger ejector which made bolt closing simpler.

Here is a short video of demonstration of how one works. We will be accepting orders for RBLPBP BRM and BRMXD beginning August 1, 2016

New Barrel Vise for Hunting Rifles

hunting_bvise

We will soon have barrel vises built per the above drawing for sale.  The vises are primarily intended to be used to remove barrels from our barreled actions that have common hunting tapers and a 1.2 inch diameter cylinder just ahead of the action.  The vise utilizes bushings to grip the barrel.  At first we will only have bushings for 1.2 and 1.25 inch cylinder diameters.  We may later offer bushings with taper to match the common berets taper barrels.

We will be establishing the selling price over the next two to three weeks.

Titanium Here We Come

We have been working for a while here on designing and producing some Titanium actions.  It is not one of my favorite materials to work with and it has its limitations in an action application.  But there are many that want the weight savings and are willing to put up with some of the disadvantages of having a Titanium action body.  The additional stretch of Ti versus Chrome Moly and Stainless Steel can make bolt opening more difficult.

 

Here are two slugs that are the throw away portion of the center of the action after we have EDM cut the bolt bore and raceways.  The slug on left is Ti and the slug on right is 416 SS.  The Ti slug weighs about 7 ounces and the 416 SS slug weighs 13.5 ounces.  It will be a few weeks before we have pictures of the first ti short action. We have not figured out pricing on the Ti models yet.
