New Mag-Fed Action Optimized for 6 Dasher and 6BR Family

The 6BR Improved cases have become very popular in tactical competitions. In fact the Precision Rifle Blog reports that the majority of Top 10 PRS and NRL shooters are now running some version of the 6mmBR Norma case — such as the 6mm Dasher, 6BRX, or 6BR Ackley. In fact “40% of those ranked in the top 10 in either league were running a 6mm Dasher”. This short, fat 6BR improved case can push the 100-107gr bullets to 2950+ fps, a well-known accuracy node. Yes the 6mm Creedmoor and 6XC can push heavy 6mm projectiles faster to be sure, but there is a trade-off in barrel life. The 6BR Improved cases represent a “sweet spot” for the tactical game, offering outstanding accuracy, with less recoil than bigger cartridges, including the 6.5 Creedmoor.

The only real downside to the short/fat 6BR-based cartridges is that they can be finicky when feeding from a magazine, at least without some modifications to the follower and feed lips. There are kits that can help with this, but now there is an even better solution — a premium custom action designed specifically to feed the 6mm Dasher (and similar cartridges) from a magazine. This action, the Borden Super Short 6, was recently, unveiled on Facebook by PRS competitor John Hargett. This action, available in both right- and left-hand versions, features a dedicated new Super Short 6 (SS6) magazine optimized for Dasher-sized cartridges. The bolt has a shorter throw than a standard Rem short action. We think this new action could become VERY popular with tactical shooters, and varmint hunters.

John Hargett says: “Installing spacer kits or possibly having a nose dive in full-size .308 mag is in the past! This will fit all 700 stocks and chassis and AICS bottom metal. So no need to change what you are already using. Borden creates a masterful action at an extremely affordable price.”

Key Facts about the Borden Super Short 6 Action and SS6 Magazine:

1. Rem 700 Footprint — The Borden Super Short 6 action is internally tailored to the 6mmBR cartridge and its wildcats, but externally maintains Rem 700 action dimensions. This means the action IS compatible with the stock and chassis you currently own. And, the Borden Super Short 6 comes in both right-hand and left-hand versions, with PVD coating available (on action and/or bolt).

2. Rem Trigger Compatibility — The Borden Super Short 6 action works with Rem-compatible triggers, and the actions are specifically timed to work with trigger of your choice.

3. Dasher-friendly New Mag Design — The patent-pending Super Short 6 magazine is sized right for the 6mm Dasher and all the 6BR family. The follower and feed lips are configured to allow smooth, reliable feeding with no “magazine nose dives”. Even with the optimal design, the SS 6 magazine will work with all chassis profiles and bottom metal made for AICS-type magazines.

Here is the description from Borden Rifles website:

“The new action from Borden Accuracy (Borden Super Short 6) features a Rem 700 short action-compatible footprint with a shortened magazine well and shortened port set up specifically to reliably feed 6 BR, 6 Dasher, 6 BRA, 22 BR cartridges. The bolt has modified Borden bumps to aid in cycling in the dirty environment. The pictured action shows our standard bolt handle and tear drop knob. Production models will feature a handle that is threaded on the end so individuals can use their preferred knobs. I have been one of the individuals that developed the bolt timing and neutral handoff with the trigger for competition shooting to minimize rifle upset in the bags when closing the bolt. These actions will be available with either the neutral timed handoff or with about .03 to .035 inch cock on close. The cock on close option has much easier bolt lift that seems to be favored by PRS competitors. For now the bolts will have spiral flutes but future versions will have diamond flutes as an option. Development work will be done to also handle the .223 Rem and the PPC family.”

6mm Dasher and 6BR Wildcats Favored by Top PRS/NRL Shooters

According to the Precision Rifle Blog:

1. The vast majority of PRS Shooters surveyed are now shooting a 6mm cartridge of some kind.

2. While the 6mm Creedmoor is still very popular, the 6mm Dasher is now the #1 cartridge among leading PRS and NRL competitors surveyed. (SEE Chart HERE)

3. If you include the 6BRX, 6BRA, and original 6mmBR cartridge along with the 6mm Dasher, this full family of short, fat cartridges is now used by twice as many top PRS/NRL competitors as the 6mm Creedmoor. And the 6.5 Creedmoor has really fallen from favor.
