New to 6BR

[spudgun]

I just picked up a Savage custom with a criterion barrel 28", 1:8 twist.

i have been shooting my 6mm Creedmoor for about 4 years now and it is a tack driver at 600 and 1000.

Been wanting to build a 6BR for about 3 years but never got around to it.

Yesterday I bought a used Savage custom receiver (single shot, 3 receiver screws).

Now to reload some Lapua once fired brass Since I have a good supply of Hornady ELD match 105 and 108Gr I am looking for load data.

What powers are working for the 6BR?

I have some CFE223, Varget, and others for .223 ammo.

Also, do I need to resize the brass or just neck size?

I so what dies are avaiable?

Any friendly info will be appreciated.

Thanks in advise.

Varget, N140, N150. You’re welcome.
P.S. spare yourself dissapointment and skip anything that says „Hornady”.

Thanks. Is there a diference between 6mm Creed and 6mmBR when it comes to accuracy.

I am getting 5" groups at 1000 yds with the 108 ELD match.

Any suggestions on bullets?

Lots of good info on the on the main site page ( https://www.accurateshooter.com/cartridge-guides/6mmbr/ )…

You are doing very well. I'd try them if you have them, but I've had better results with Sierra and Berger. Varget was the powder of choice for a long time and you should try it if you have it. I've switched to N150 based on availablity and cost. Shoots just as well maybe better.

If 30g of Varget or 28.5 of N140 doesn't work...there's something arwy. Start with Sierra 107's. 5 thou off the lands. Iassume that there's a load for CFE, but I have not tried it, as I avoid double base powders where possible.

Double base = Faster throat erosion….
Some of those powders shoot well… BUT, there is always a price to pay… Aside from the actual cost of the powder.
Definitely Varget {AR2208} and the 107’s is a good base starting point.

Many 6BR shooters say if it won't shoot 105 gr. class with 30 gr. of Varget there is something wrong. Back when I was shooting the 6BR I found it to work very good.

Berger 109's are good
Lapua 105 Scenar - L are great and very consistent bullets
I prefer 115 Dtacs though for the highest BC at 1000
FWIW - I've gotten pretty consistent 1/3 or less MOA with Dtacs at 600
Shown pictured is running a 2 shot waterline test at 600 bumping up my load
against 1 inch square with Dtacs
Hbn Coated
According to the guys who dominate 6mm
103 Vapor Trails are very hard to beat for the best consistency
I haven not tried them yet but will eventually
------------------
Don't know your twist but Imagine it is a 1:8 twist which should be fine for all these
For practice bullets the 6mm 112 Matchburner are surprisingly good
I found them better than Hornady's

Good info so far. Keep it coming.

I just ordered dies for the 6BR and a 20 MOA rail.

Cant wait to get some loads for ladder testing.

One other question, the seller gave me 150 once fired brass. It's a mixed batch of Alpha and Peterson.

Should I separate the cases and do data on both cases or are they close enough volume wise to not bother.

I would definitely separate the two.

 

[HTSmith]

Don’t mix the cases

The Hornadys of any type dont hold together well when driven too hard.
hence why I decided I coudln't do worse by trying matchburners.
At one time you could not get Dtacs or Sierra 110's for nearly 2 years
So I was experimenting around with what was more available.
I had to go to Gunbroker just to buy old Berger 115's, they were unavailable too
Which is then when I also found:
there is a difference in jacket thickness between the Target 115 and the (Newer) Hunting 115
Hunting is thinner like the Hornady, made the mistake of buying some Hunting 115' and they were blowing up too
Only reason I tried Berger 109's Hybrid at one time is because they suddenly became available first before their others.
Found by a search, many other Matchburner calibers have shown good results too
-------------
Since, I have restocked on Lapua 105's , Berger 115's, Dtac 115's, and Sierra 110's
So havent revisted the 112 Matchburner in awhile, but they did perform
So they're a decent well kept secret.
I avoid any Hornady in 6mm though, They never make it 100 yds in tact due to the thin jacket
6.5's and 7mm Hornadys run fine, just the 6mm jacket is a touch too thin to hold up
.023" vs .030"
That extra 7 thou of copper on each side obviously soaks up a lot of heat retaining jacket integrity
-----------
pic is how Hornadys perform for me,
notice the comet tail showing they're about to come apart and the large group spread
Compared to a 6 shot group of Dtacs
I was decently happy with how the Dtacs were performing (I mean all shots touching is nice but.....)
until I found I needed to be into the lands another .025", then the groups shrunk by half
My gun tends to like anything in the 110 to 115 grn range

For my 6BRA, I've used Varget, N140, N150, N540, AR-Comp and H4350. I mostly shoot 107SMKs w/ N150 at 2830-2850, but AR-Comp with Berger 105 Hybrids at 2900 is one of the best shooting combos I've found (1-3 - 29.0; 4-6 - 29.3). For Dies, send 3, 3X fired cases to Harrells, they'll send you back a die that best matches your chamber.

I would interject, you will be wanting a 7.5 or 7 twist to stabilise the 110’s and up…
Were you using the 115 Dtacts in a 6BR or a 6CM?
I would think that there is just not enough powder capacity in the 6BR to make the 112-115’s perform, especially at a 1’000.
I would think that they would be falling subsonic by then…??
The 103’s that I used one year in F Open were real performers but struggled a bit once past 600 unless conditions were good as the heavier 6mm and larger bullets with the larger cases just bucked the wind better.
Using the mighty 6BR to 600yd now and then to the 7mm for longer distances these days just to keep the rest of the crew in line…
I did take out a club F Open with the 103’s but the planets were kind and the Dasher that was chasing me fell short that year…
Currently using Sierra 107”s again now that they come factory pointed and they are a bit more forgiving in the wind. Recent 500yd clean of 200.14 so they definitely are working well in the 1:8, 28”benchmark barreled Eliseo R5.

I shoot the Berger 115 Target VLD's for my Ram load in Silhouette with a 6BR. Your question peaked my curiosity...

My speed is ~2740 fps and a quick tabulation on the Berger ballistics calculator says that it would still be going ~1435 fps at 1,000 yards. It would go subsonic at around 1,300 yards.

5" groups @ 1000 yard with 108 EDL match and you're asking for bullet recommendations??? You ALREADY know what you're doing!! Maybe WE should be asking YOU.

The Barnes 112 is one of the hidden gems on the market.

Sierra bought Barnes.
