I have a Remington 700 in 6 mm BR that I owned for the last 20 years and seeking to have a new barrel built for it plus a McMillian A5 stock and Jewell trigger. There are new calibers in 6 mm like the 6 x 47, 6 Creedmoor, etc. It will be a target rifle mostly. Which caliber would you recommend that is more accurate and longer reaching range possibly 1,000 yards? I see that the BR is a lot smaller than the 6x47 and Creedmoor and won't have the ability to reach out and touch them. I like to use Lapua brass and what twist do you recommend? Seeking some input from you gun fanatics. Thanks

Noticed that Lapua do not offer brass for 6 x 47 or 6 Creedmoor, needs to be necked down from 6.5 to 6 which is a pita. Would I need to turn necks or any issues I need to look out for if I go that route?

I will be sizing Lapua 6.5 Creed brass for my 6 Creed. My understanding from some knowledgeable folks here is that neck turning will not be required.

You might experience a donut close to the case neck shoulder junction more on the neck after a few firings. Not sure since your downsizing the neck and I'm expanding 6.5 to 284. I'm sure Chad or Fireman can go more into detail.

The important issue for you is the twist. If you are wanting a target rifle
to shoot out to 1000yds, you will want to use some of the new ultra high BC Bullets. These are long and require a faster twist than typically found.

I have necked down a bunch of 6.5 to both 6mm and 22 Creedmoor and the only problems I have experienced was donuts while using bushing Dies. Once I got a FL Whidden die for each all the donut issues went away. I take Lapua from 6.5 to 22 in one pass and load and go hunting.

I use whidden FL Whidden bushing die. I found out if I turn the necks before I load or on new brass they don't donut. But at first I wasn't turning the necks. After I started turning the necks I had to buy another bushing.

I neck down Lapua 243 cases to 22-243 with a FL Redding die and have not experienced the donut with those. the chamber on the 22-243 was reamed for the neck thickness of the Lapua brass being necked down.

Easiest just use 243 or 6mm Remington case with a barrel with twist rate for the hevier high BC bullets.

6mm Creedmoor brass does exist.

Give it a 1:8 and load a 115 DTAC, or a 110 gr SMK.

I don't think the donut will be an issue when you neck down, it's when you neck up and a part of the old shoulder becomes the new neck.

What do you think about the 6 BR Ackley? I still have 200 or so pieces of BR brass.

If you're asking me,, I don't think about it...but I'd say that if you like the cartridge and accept its limitations, go for it. For my part of it, going with something a little different is far more interesting then treading the beaten (and rutted) path.

The little br case would do everything you ask and everything any of the suggested calibers can do with less powder and more accuracy. If it was me I'd go with an improved...brx or dasher though.

Good luck!

I agree after some reading, but its a pita fireforming and case prep. I just want to buy brass and shoot. I see Norma makes Dasher brass.

I shoot a wee bit of 6mm.




While I shoot a plethora of various Improved chamberings,THE beauty of the 6BR,is it's outta da' box splendor. I've only got two 6BR's and both are 1-8"...the "long" one is 21",though it started out at 28". Hint.

Primal AICS guts,are a nice way to fly. Hint.




I shoot my Custom Montucky 6BR a bunch more,due it's obvious Utility and it is a hammer.



Hint...............

Thats true, but once you find the sweet spot I think .243WIN is better than the BR's and CM's.....I've been wrong before.......

So find pressure, and shoot a bad shooting load, and pass up a good shooting load on a lighter charge?

That's a bone head move.
