I have a Schneider 6mm - 7.5 twist #5 fluted barrel- Stiller Predator action- Mcmillan stock- jewell trigger waiting for a new build. I was thinking of a 6mm using 115 grain berger hunting vld's(have 600). I am undecided about caliber, I was thinking 6xc - 243 or 6x47l. It will be a hunting - shooting rifle. I have one of each and am leaning towards the 6x47l. I realy like my 6.5 & 6x47lapuas that I already have. Very open to all suggestions.

I am currently building a similar gun, Krieger 6mm 7.5 twist, Stiller Predator action, Timney 2-8oz trigger and GRS long range stock.
I will chamber in 6XC, already got a 6BR and .300 win mag.
the reason for 6XC is amazing accuracy at 600-1000m with 105-115gn bullets.
I want things simple, and since Norma has 6XC cases then I'm ready to try this caliber.
I don't want to fireform or do any modification on my cases other than trim and neckturn.

I WAS in the same position you're in. I decided on the 6-6.5 x 47 for a few reasons. The FIRST AND FOREMOST is the use of a small primer by the '47. You can ALMOST not ruin a case.. The primer pockets, even under pretty stout loads, stay tight. Anyone shooting a 6.5 x 284 OR a 284 (and it's siblings) knows that if you even TRY to push those BIG bullets, you will have very short brass life, via expanded primer pockets. I know as I have a 6.5 x 284. I have burned out 2 barrels on a 6.5 x 47 and have NEVER experienced loose primers... Now admittedly, I have not tried a 6XC... It's brass may be a lot more resilient in the web area>>>I just don't know. At any rate, with the 6-6.5 x 47, you can drive 105-108 bullets at a comfortable 3075f.p.s. I am quite sure you can drive the 115's at 2950+ with the 6-6.5 x 47... It is JUST as easy to make>>>simply chamfer the OUTSIDE of the case neck well of your 6.5 x 47 brass and run it in your 6-6.5 x 47 die and you,re in business! Also, if you notice, all the "siblings" of the 308 Win. case are ALL very accurate. The same will be for the 6.5 x 47.

well.. the need might be less than the want.. I just turned some of the brass and it actually needed it.. just cleaned the neck with the neckturner, still a few spots that the neckturner didn't clean so the necks were a bit uneven...
Re: looking for 6mm build advise
I am looking for a 6mm build for competing in VBR 1000yd. My present heavy gun is a 6br and I have lost cases to loose pockets with as little as 3 loads with norma brass and they are small primers pushing 105 a-max and 107smks Ben. My light gun is a 25-06 pushing 115 bergers at a stout 3,125fps and have not had any primer issues, just split necks and the case necks splitting lol. I am interested in the 6-6.5x47 and the 6xc because of the ability to buy brass or easy resize. I would like the dasher but not sure of any gain for the work involved in making brass. Accuracy between them with a 105 to 115 bullet is what I don't know about, all thoughts welcome.

my 6 xc has served me well. I am pushing the 115s (DTAC)up over 3100 through a 30 inch barlien (7.7 twist ). I noticed a bit more wieght variation + or - 5 grains in my new batch of norma brass. That said I loaded it staight from the bag and have shot 2 cleans in a row. I will be the first to say I like the large primer hole better than the small. Use H4350 and never look back !

Howdy !
I'm use a 6mm wildcat, chamber made by running a 6mm Remington reamer in " short"; to obtain a .466" base diam.
I utilize 7X64 Brenneke as the parent brass.
This wildcat I call " Deep 6 " which has case capacity in the 6XC - 6X47 range.
By making use of bottom-portion of the 7X64 case, the resulting " Deep 6 " cases are very robust, and have the same long neck and easy-to-form 26* shoulder angle of the 6mm Rem.
7X64 Brenneke is one of the few Euro-spec cases that SAAMI keeps data on.
Deep 6 can be formed. loaded & re-loaded w/o having to $$$ custom dies; or custom reamers.
Brass forming is easily accomplished using a stock 6.5X55 Swedish FL die ( Lee )as the case forming die. The die has its internals removed, to make it open-topped.
I use Norma brass, but there is also RWS, Hornady, and Speer brass offered.
While Deep 6 is easy to form/load, wildcat brass forming ain't for everybody; esp those who need to have a high-quantity of cases on-hand. I myself enjoy the whole exercise, and ultimately ... the use of a well-designed/good performing wildcat.
