6BR verses 6 Creedmore
- Thread starter dreever
- Start date
243 Win ...................................... introduced in 1955.
6XC .. designed by David Tubb, so of course he shoots it
, and very well too, and in use for around 20 years now. The XC moreover follows on from many previous experiments with the 250 Savage case necked down to 6mm one even used by USAMU in the 1960s.6BR two, three generations of use in various forms since the first necking down experiments with Frank Barnes 308 X 1.5" wildcat in the early 1960s. The 6mm BR Norma variant was introduced in 1996 and this kicked off a massive expansion in its development and use.
6BRA ........ an adaptation of the 6BR, one of many over the years. Without belittling the BRA or its users, minor variations to 6BRs come and go, come into and go out of fashion just like the many minor variants of the PPC in use in short-range BR.
6mm Hornady Creedmoor ............. introduced 2016 (?), 2017 (?).
It's maybe a mite early to say anything about its long-term success or otherwise. It has two pluses that give it a good start - the sheer amount of interest in the Creedmoors means there will be lots of attention and development, and secondly / crucially it meets the essential prerequisite for a successful accuracy cartridge of having very good brass available given the number of companies making quality versions of the parent 6.5 version in both large and small primer form.

With Lapua brass, small primer, ability to seat 105s up the neck and fit in a magazine, I think this is a great little case. It will be popular. Its not a Benchrest cartridge and was not meant to be. I have never seen a 6mm bigger than a dasher that would agg with a dasher or smaller case. I do not believe a 6 creed with shoot with a 6br,BRA,Dasher, but we will have one shooting our 1k matches next I hear so we will have to see. The 6x47 has been tried in the past, its shoots great, just not small enough to best a BR based case on an agg.

I am sure it is a fine cartridge. Most shoot better than the people who own them.
Now, there's truth indeed. One has to be very careful in using the word 'ultimate' in any aspect of rifle shooting, but challengers come and go and no matter what they achieve elsewhere, the Dasher combination still seems to retain its 'ultimate' accolade for BR other than in the short-range game.
You get your Creedmoe's, 243 with 30 and 31 degree shoulders and when it comes down to accuracy they will not shoot as small as the Br imped cases. I tried a few and to get them to shoot in a.1 or close, they are at the same speed burning a lot more powder. They are not efficient or accurate, I ran the Dasher at 3100 at .2 and it doesn't agg. up there, drop it down to 3000 or less and it will. Trying beat a condition with speed doesn't seem to work. You may get lucky once in awhile, but accuracy always seems to be on top..... jim

The dasher is on the top end of case capacity for agging in my opinion, seems like some days its over the top. I think this is why we are seeing so much success with the improved cases lately. At the top level, small things matter. The grinch and others based off the grendel case look interesting as well.
Get your feet wet ...6 BR Imp. you will never go back to a BR...... LOL.... jim
Jim, I have a new Benchmark on my 600 yard 'Light Gun' in plain Jane 6mm BR and a round count of less than 100. With its limited use, I suspect this barrel and chamber will outlive me now.
The KISS principle applies to me and BR ......... whereas in F-Class (my real love) I constantly ruin both prospects and barrels through rash and needless experimentation with new (to me) cartridges, bullets, powders.
I think some guy won both the 6 match group and 6 match score aggs at Williamsport this past season with a 6 x 47 lapua ? ? ? ? ?

All kinds of things can and do happen on limited basis. Lots of guys have shot the 6x47 and the limited success its had tells the story, for Br anyhow. Heck, the world record for small group was with a 300 hulk

I was lucky enough too avoid that '' 6x47 Lapua '' on my relays, Very, Very nice shooting Mike !

I think George Gardner qualifies as more then just tacticool. I personally have both and my trg chambered in 6 creedmoor shoots extremely well. No I’m not Whidden or the likes but I was able to shoot this 5 shot off a bipod prone at 1000. I don’t anneal my brass, I don’t use a 5000$ powder measure, I don’t weigh brass or bullets and I don’t turn the necks so I’m thrilled with the 6 creedmoor.
Now that was good. I commend you Laurie,you have an open mind...and it very apparent you know what you are talking about...and you also set folks straight in a polite manor.
