6xc vs 6.5x47 vs 6br

[Mudder]

Hi there
I'm looking to build a couple rifles. Right now I have 308, 6br, and 6ppc. Looking for accurate additions to the collection, most likely for 600 yard BR or F class.

Generally prefer not to make special brass so I was hoping something like a 6xc or 6.5x47 might offer accuracy on par with a Dasher.

Thank you for any help!

I like my XC a LOT ! Its probably the least finicky cartridge I have ever loaded for. Unfortunately, finding norma brass for it is about as likely as seeing big foot and the loch ness monster doing a synchronized swimming routine. Look at wind drift and bullet drop . My XC pushing 115 DTACs at 3050 , 1/4 MOA makes me hope my competitors are using a 6br or 6.5 x 47 ........ Let the wind blow, it keeps things interesting!

Just my opinion, but there is no wrong answer to your question. Both are or would be great choices.

I chose the 6xc in a no turn neck in a 9 twist barrel as most of my shooting is under 500yds and bullet selection in 6mm is unparralled. You might want to consider an 8 twist for your 600yd shooting.

The 6xc is an easy to load for round, the norma brass has been good to work with and so far I've never had any trouble getting it. Properly smithed, properly loaded, and properly shot by you and I'm sure you'd find a lot to like about the 6xc. WD

I had a 6XC but felt I needed more HP to push the 115s in "MY" rifle so I had it rechambered to a 6SLR and was also very pleased with it. Brass is easy to come by and the fireforming is as accurate as the fired case so you loose nothing.The other thing about it is, its very easy to load for. Mine shot H1000 and H4831SC into tight little groups. I actually stayed with the 107s because they just shot so well.

Hey Mudder! Have you considered a 6-6.5 x 47? It is ballistically the same as a 6XC with 2 nice advantages: 1.) readily obtainable 6.5 x 47 brass and 2.) that brass has small primer pockets which will almost never loosen up! It is merely a matter of getting new 6.5 x 47 brass, running them into a mandrel to "iron out" and dents etc.. then chamfering the case>>especially the outside of the mouth and simply running them into a F/L die! I use that method for ALL my brass, forming new cases for my 6-6.5 x 47 or ANY cases... My 6-6.5 x 47 shoots DTACS at 3010f.p.s. with room to spare! It also shoots them nearly as accurately as my 6mmBR! Those DTACS at that velocity should be THEE ticket for 600 yard work! AND remember, brass is EASY to come by...

My advise to you is to go with the 6.5x47

Lapua brass, small primer pockets, many bullet choices available, excellent accuracy, and great ballistics.

I saw a couple post where the guys mentioned consistency problems with the 6x47L. Both said they were going back to 6br. Have you seen anything like that ?

 

[Mudder]

Would any of you guys say bite the bullet and go Dasher instead of the other choices ?

 

[ShootDots]

Well Mudder, I can't say what those fellas were having trouble with... But if you get a 7.5twist barrel and use either DTACS or Berger 115gr bullets with somewhere between 37 and 38.5grs of H4350 you should not experience any problems associated with that cartridge.. It took me all of 3 times out and 75 rounds of reloads to find my accuracy load. My particular load is 115 DTACS seated 7-8K into the lands, 38.1grs of H4350 and CCI 450's. It gets me 3010f.p.s. with accuracy between 5/8th of an inch and 1.125inches at 300 yards! That is my experience with the 6-6.5 x 47...

I've read those too. If you read and believe enough of these you'll end up confusing yourself into buying nothing. Lets face it some could mess up an anvil. I shoot against more than just a few 6x47's, 6.5x47's, and Dashers. All are very capable in the hands of a good shooter/reloader if they are properly smithed. Regarding your question about the Dashers.... yes.... very formitable round..... it all depends upon how willing and capable you are of fireforming.

The bottom line on your request is that you have chosen an excellent shortlist of rounds. Now just decide on whether you want to fireform or not, and get a VERY good gunsmith. WD

Thanks guys. Advice greatly appreciated !

Waderthemudder,

Don't go with the 6XC, been there and done that. I know alot of guys, built a 6 X47L and could not keep them shooting. For 600yd Benchrest, nothing can run with the 6BR and 6BR IMP ( 6BRX or Dasher ) Do you see the 600yd record shot with a Dasher. 0.349"

I can say that Ive had 6br, brx and now the 6x47 lapua. They all shoot well. Brx is great if you dont mind fireforming. I chose the 47L because my dad now shoots also and he went with 6.5x47 and we use the same dies, cases, primers and powder. All are easy to load. I just shot a three shot group to sight in my rifle at 500 yards into 1.525" group off a bipod. If you are going to shoot 600 and in, any of these would be perfect. Just choose one and dont look back. I do however think that a "committed"fclass/benchrest shooter, that shoot midrange, should have at least one 6BR in their life. They are fun and easy. Good luck.

Waderthemodder,

You may want to reconsider one of the 6MM cartridges that you have to form the brass for. If you don't, you will be leaving winning attributes on the table. Mark is spot on, my pick is the Dasher.

 

[Mudder]

Dasher is the one I really want. I think I'll just have to learn fire forming. I have two Bat M actions so I'm thinking Dasher and 6.5x47L.

I suppose there are much harder choices to make

If you are thinking Dasher, don't forget the BRDX. Accuracy = same. Neck a little longer which makes fire-forming a little easier, and you have a little more flexibility with bullet seating. My BRDX is making 3000 fps no problem -- this with Varget and 105 Scenars.

Kiff, JGS, Manson all have reamers. Whidden makes dies.

Ive been watching that one with interest. It seems like its easier to form brass for. True?
