Sunday Gunday: Practical Tactical 6mm BRA Rifle for PRS/NRL
That’s custom paint on the stock, NOT a Hydro-dip coating. Impressive paintwork!
Our Sunday GunDay showcase rifle belongs to Shane Sivertsen (aka SoDakDasher in our Forum). This eye-catching tactical rig was smithed by Travis Stevens at TS Customs in Miller, South Dakota. Shane tells us that Travis is a “top-notch builder who builds tack-driving rifles that are still extremely shooter-friendly. Plus he is one of the friendliest guys you’ll meet.”
This rifle features a Lone Peak Fuzion Action with Trigger Tech Diamond trigger (flat shoe). Up front is a Benchmark 26″ MTU barrel chambered in 6mm BRA (a 40-degree 6mmBR Improved “BR Ackley”). It’s all nestled into a McMillan A5 stock with adjustable cheekpiece. Getting him on target is a Vortex Razor 4.5-27x56mm optic in Hawkins rings with a Vortex throw lever on the power ring for quick magnification changes. The Atlas PRS Bipod rides on an Area 419 ARCA rail up front. The barrel is finished off with a Piercision 5-Port Self-Timing Muscle Brake.
Custom Camo-Pattern Paint Job
All work on this rig was performed at TS Customs, including Cerakoting the action. The pattern on the McMillan A5 stock is NOT a hydro-dip! That is a custom Kryptek camo paint-job done in-house by a TS Customs employee. Shane liked the Kryptek pattern from day one: “It’s always a good thing to do something a little different to your equipment to stand apart from the rest of the pack.” Shane says the paint pattern is the first thing everyone notices about the rifle.
6mm BRA Chambering
Shane spent quite some time trying to decide which 6mm cartridge to choose. After much deliberation with Travis, he chose the 6mm BRA (aka “6BRA” or “6 BRA”), mainly due to the reputation this little cartridge has earned for accuracy and ease of tuning. This rifle is Shane’s second TS Customs-crafted rifle: “the [other] is basically the same action/barrel combo but set in an MPA chassis and chambered in 6mm Dasher.”
Excellent Accuracy with Varget and Berger 105gr Hybrids
Shane’s 6mm BRA is showing impressive accuracy: “Thanks to Mother Nature this spring (with cold, snowy weather), I have only been able to get 100 rounds fire-formed and the barrel broken-in. I started with 30.5 grains Varget in Lapua BR brass with CCI 450s and topped off with Berger 105gr Hybrids. Velocity averaged 2830 FPS with an SD of 4.7 from 10 rounds randomly picked from the lot.”
Shane knows there’s still more load development to do. But this rifle is grouping under one-half MOA and Shane says the gun can definitely out-shoot his abilities. He admits it’s still a work in progress but he is happy with the gun’s performance so far.
Shane praised his Piercision 5 port Muscle brake. Shane tells us: “While I am a suppressed shooter by preference, I wanted to give this brake a try. It works very well — the control and ability to stay on target for followups is remarkable. This brake works perfect on my 18-lb 6mm BRA and will be used indefinitely. Plus it will be a little payback to the other big-braked shooters on the line.”
While it’s still such a new toy, Shane doesn’t expect to make any modifications in the near future. However he says he might “upgrade to a Tangent Theta optic by the end of this season.”
Below is a comparison between the 6mm BRA and the 6mm Dasher. The Dasher has slightly more capacity, but a much shorter neck. There is some evidence that barrel throat erosion may be slower with the 6mm BRA, and the 6mm BRA is easier to fire-form.
