6 SLR is on my list of "gotta have someday" chamberings. Got a McMillan A3-5 ready for a 700 (or equivalent footprint). Although I do like the idea of a Panda, Bighorn, etc. that I can have chambered without sending my action off.
Which is "best". 6 x 47, 6XC, 6 Creedmore, 6SLR??

Its to fast for PRS. You are limited to 3150fps and that one will push them to 3300 unless you jump to 115 Dtacs. Then your are still close. Nothing is worse then building a rifle that has a great accuracy node at 3180fps but you have to cut back to something slower. If only someone would make som 118gr Dtacs lol

Could you not go for a lower node, still get great accuracy, and have brass that lasts longer? Of course, with PRS and 'lost brass' stages I personally wouldn't be inclined to use anything that involves case forming... but I wasn't really looking at it for that either.
I have 2 6XC barrels and 2 6SLR barrels for 2 Savage actions. Plus a Pierce/Krieger 6SLR that is likely recently sold. I like them all. I expect to get 2500 rounds out of the 6XCs using 7828ssc powder. But I expect to get more than 3000 rounds out of my 6SLRs using H1000 powder.
I run new 6XC brass thru a 6XC die, then shoot it. I run cheap Winchester 243 brass thru a 6XC die screwed out .122" for the 6SLRs. The Winchester brass costs less than half that of the Norma brass.
I like both cartridges. Both are very accurate. Velocities are very similar.
By the way, the Pierce/Krieger 6SLR won every mid range match at the South Zanesville (Ohio) range last year.

Absolutely loving my new SLR
Got a related question for your SLR owners. Can you tell me the h2o capacity of your case? And, do you happen to know for sure the h2o capacity of the 6.5 SLR?
Bill, did you find those Savage SLR barrels premade of did you have to chamber them?
Thanks,
Terry

I am a 6mm Competition Match fan and have been since 2007. If I did not shoot this cartridge I would be shooting the 6SLR......... While I was waiting on Dave Bruno to chamber my most recent 6CM, which is what it was referred to way before the 6 Creedmoore came out, I started shooting a .243 using H1000. It hammers with a 105 Hornaday. The 6CM will be up and running eventually, but first I'm gonna run this .243 a bit.

Preacher chambered 3 for me. First he chambered a Bartlein with his reamer. That was a project as was 1.250 for the first 5 inches then tapered to .970 at the muzzle. Preacher didn't like the step up after the barrel nut, so he turned the barrel down to the tenon diameter.
Then he built the Pierce rifle I just sold - Krieger barrel, 1.250 straight, no taper.
Then he ordered a Brux barrel for me. 1.125 straight, no taper. He chambered it for me using my newly acquired reamer. That one is a beauty, the barrel nut (large shank, PTA) goes right over the barrel, tenon is cut directly on the barrel. That 30" barrel plus 10" of suppressor has accounted for 444 groundhogs so far this year.
Almost forgot, Preacher ordered 2 Brux barrels for me. The second was chambered in 6XC with my reamer. It went on my new Ohio State Buckeyes Savage.

Lapua brass (yes Im still trying them) ran rite on 53.8gr H2o, Win Brass im currently using in my SLR avg 54.6gr H2o, Win brass a buddy of mine is working on for his 6.5SLR is rite on 55gr
As FJIM noted the 6XC was designed from the ground up. David Tubb spent many years shooting both the 7-08 and the 243W before designing the 6XC. He obviously saw the weaknesses of both and designed what he felt was a better cartridge. There are many claims that the 6XC is more efficient than the 243W but I only partially agree with that statement. I think that the powders used like H4350 are a better fit for that case / barrel / bore combo rather than the design having anything to do with it. Powders are developed for a wide variety of uses and H4350 just happens to be ideal for the 6XC and when the powder is ideal it makes it easier to load IMO.
As far as what you see in PRS, that changes year to year. If someone wins the PRS championship this year with a 6XC you will see a mass migration to that cartridge next year. If someone wins with a 6.5 you will see the number go the other way. The 6XC dropped way off in 2015 with only 2 shooters in the top 100 using it but I would not read anything in to that. I heard brass availability may have been an issue. I shoot practical matches with a 6.5x47L and for whatever reason it has made slow progress to the top but is now number 1 as of 2015 within the top 100.
In the 6mm's my vote is 6XC. I don't own one but that is what I would build when looking at all of the 6mm's.

Well rifleman 700 I partially agree with you but I prefer RL17 in my 6XC and I am liking RL26 real well also. I have two almost three years in with the RL17 now the RL26 has been about a year and it is shooting well but I feel still unproven maybe this time next year I will know if the load holds up well. H4350 I can tune it to be a little more accurate but the RL17 has gave me 100 to 150 FPS more speed and it can be as accurate to slightly less. RL17 I get 1/2 moa to slightly less at times now I can and have shot 1/4 moa with the H4350 so for what I do with both rifles I go for the extra 100-150 FPS and 1/2 moa is good enough and sometimes it is slightly better than that with the 100 FPS more speed. I actually shot some RL23 shot great. shot some Ramshot Hunter shot great. Shot some H4831 shot great. But the 105 bullet has performed well for me at 3,150 FPS so I like it there. The 115's have shot great from 2,950 to 3,150 FPS .
So really I have not shot a powder in the 6XC that it has not shot well. the difference seems to be in the Bullets and barrel as far as how fast you want to push them. So it has been stated kind of reminds you of a .308 Win. just shoots about anything you stuff in it.
A few guys were shooting IMR7828 and said it shot great.

^^^Here is why I don't like RL17 - my opinion of course. 95% APB burned in the first 7.8" - barrel burner. Full burn at 15" indicating it would probably be better in a shorter barrel. Also RL17 burns really hot also contributing to barrel wear.
^^^Here is RL26. Same as RL17 except adding that its a compressed load. I tested this powder in a 7saum and really like the velocity and accuracy but did not like the heat generated and the throat erosion properties of this powder. My opinion of course as I like to shoot and not replace barrels every 1200 rounds.
+1 on the 308W.
I went 6x47L. I barely have enough time to load let alone mess around with all the brass forming. New 6.5 brass through the 6mm non bushing die, through the bushing die after that and load them. They feed out of a 10 round AICS mag perfectly, the longer necks have a bit more bearing on the bullet so if you end up being a bit rough with your ammo it doesnt care. IMR 4350 and 4451 have been working great with 105 grain Berger Hybrids. I am just waiting for the Mausingfield to arrive now.
well yes I can see your point using RL17 in a competition setting. But I am using it as a Hunting Rifle or just fun shooting so I don't shoot long strings or get my barrels hot. My 1-8 twist has right at 1,200 rounds on it and it will still shoot a .300" 3 shot group at 200 yards. So the RL17 has not hurt it any actually I think it shoots better,nice and broke in.

Ballistically, they're all similar. In terms of brass, though, there's quite a difference. I have an XC that shoots very well, but if I were to do it over again, I'd probably go with a 6 x 47 Lapua, since Lapua brass seems more predictably available and it has a small primer, which is plenty for these cases. I'm not a fan of "wildcats" generally (who has time for all that?), but necking up/down isn't the end of the world. This assumes feeding is a good thing. For single load only, there's nothing wrong with a 6 BR (and some folks seem to manage to make these feed well too). For something were brass is going to be lost a lot, why not a .243? It's cheap and everywhere.
