Which is "best". 6 x 47, 6XC, 6 Creedmore, 6SLR??

[6xcshooter]

I read people saying on here that a 6XC will equal or shoot faster than a 243. I think this is some BS IMO. Larger case capacity and more powder burning in most cases is going to gain greater velocity. Case and point: I have a 300 WSM and my friend runs a 300 win mag. Once you get over 180 grain bullets, my 300 WSM cannot reach the velocities of his 300 win mag. This is the same concept for a 243 and a 6XC. I considered re barreling my 243 to a 6XC, but I see no significant improvement for my use. I can care less if my 243 burns 6 grains more of powder honestly. I can get Lapua brass for mine and 243 components are commercially available EVERYWHERE in the world. A 6XC is not. I'm on my second 243 barrel and I've learned H1000 definitely extends barrel life if you want to argue that factor. The only thing the XC has over the 243 is the case design. And with that being said, the 243 was developed in the 1950's and still WORKS as well as a 6XC. Good luck.

It's no B.S. the 6xc is more efficent than the 243. It will out do the 243. with less powder!

260 Rem - 6.5SLR - 6.5 Creedmoor - 6.5x47 Lap

The above image is of the 6.5 versions, but the only real difference in making any of them 6s is just necking down.

The SLR versions in 6.5 or in 6 have the most capacity of any of the wildcats except the 6Competition Match or either of the 308 based cases (260 or 243) blown out to an AI.

Most wildcats strive to get greater capacity from the parent case, but the SLRs are different, they just try to improve the shoulder angle and get a longer neck, so as wildcats go the SLRs have the distinction of not requiring fire forming, you push the shoulder of the parent back at the neck and leave the body/shoulder junction at it's original location, so all you do is run new brass in a die and load it.

243Win - 6SLR - 6XC

I believe I see a 6.5 SLR in my future soon, with a 6 SLR to follow ;-)

Although I did just notice the only thing I do not like about the SLRs. The shoulder diameter on the 6mmAR reamer prints is only .454 Seems a bit narrow compared to the rest.

 

[Capt. Oblivious]

Just finished fireforming another 50 pieces off lapua brass for my 6SLR with some 95gr Ballistic Tips. First 25 at 109y went into a group the size of n berry, around .4", second 24 (had a dead primer) went into a half inch group. Cant get enough of the rifle been shooting it 3 time a week lately. Next barrel is on the way and it will get chamberd by the same smith with the same reamer, it hammers with 95gr Bergers and bluebox brass

Looks like the 243 and SLR clearly have capacity advantage over Creedmoore
The 243 over the SLR.

....and therefor a higher velocity advantage.

I'm on my 2nd 6 SLR barrel, it's a viable case. Just some insight, I shot 600rds of 6.5 slr before I pulled the barrel. Unless you are willing to neck turn donuts out of premium brass, the 6.5slr really brings nothing to the table the 6.5 creed wont handle. You form Win brass and remotely lean on it, 4 firings max on your brass.

 

[lloydx2]

What about the straight 243. Or Maybe 243 imp - 6 competition match.
The last 2 are basically the same thing, When someone reinvents the wheel
They always want to rename it. There is no one (Best) It depends what
you want to do. If your worried about magazine restriction with long bullets
Or barrel length. The 3 above might not get it. The SLR will also give you
speed and more seating flexibility with long bullets in magazines (long neck)
Its the only one that will do both. But you still need to have barrel length.
So what do you want? 1k Sling - F Class or PRS

I dont think your going to be able to shoot the difference between any of them. The cases are all so close in size. If the 6x47 has accuracy issues, then they all do. None of them are going to shoot like a 6br or dasher and win benchrest matches, but they will all be capable of .2-.3s. I just built a 6x47 because I like the brass quality, long neck, and small primer. .90" freebore and I can shoot 60 grain sierras at 3900 fps and 105 vlds at 3100 fps.

 

[lloydx2]

It depends on what level you shoot at. If you are a F or Slinger that shoots a 9
that is a 1/4 inch out in a quartering wind you might rethink that.

Will the BRX compete with the Dasher in accuracy?

 

[Alex Wheeler]

Will the BRX compete with the Dasher in accuracy?

Yep

 

[goneshootinginAZ]

Yep

I think the new pending record for F open at 600 yds was shot with a BRX, at the SW Nationals not long ago.

 

[lloydx2]

Yes Lester Bruno Did it at 600 not 1K. It was also dead calm.

 

[B_Thomas]

What are the avg. velocities of the 6SLR with good accuracy? 105g bullets?

I think most are running 105 class bullets in the vicinity of 3100 to 3200 depending on barrel length.

 

[Frankr]

you can buy this rifle chambered in 6XC . why a 1-9 twist is beyond me. I called about one.I think it will eventually be a factory chambering.

http://montanarifleco.com/?page_id=149

Now I see they are chambering the 6 Creedmoore and give it a 7.5 twist...I could kick them right in the balls..

I have a buddy who bought one of the Left hand models in 300 WSM and they are nice rifles. I would have bought one in 6XC if had at least a 1-8 twist now looks like I will have to get a 6 creed.

Non of the other 400 shooter there shot in the dead calm of it?

 

[lloydx2]

What caliber won the match. What happened to Lester after the first agg?
Not going to get into the best cartridge for F Open debate. Already been beat to death
Oh btw I shoot midrange sling with a Dasher.

 

[JigStick]

I just recently started tuning my 6x47 built by Dave Bruno on a Stiller Tac 30 AW and a 1:7.5 twist 4 grove 237 bore 26in Krieger barrel. And this thing hammers. I'm EASILY pushing the 105 hybrids over 3150fps with H4350 with minimal compression. Primer pockets are still tight after 5 firings . This gun hammers, running neck and neck with my buddys 6 Dasher.

FWIW my buddy could just never get his 6CM to shoot consistently. one day it would be on fire, and the next day throwing fliers left and right. He switched to the 6 Dasher and seems happy so far. We did notice that the Norma 6 Dasher brass blew its primer pockets out after 3 firings. As well as some case shoulders during fire forming. Now hes back to fire forming with Lapua brass.
