6x47 Lapua or 6mm Creedmoor

[urbanrifleman]

Worse brass, little less velocity, terrible name, and no history. I’ll stick with the 47L case.

6xc is a good alternative also. Tubb sells very good Peterson brass for $68 per hundred. I like the small rifle primer.

Here is my load workup with Berger 108 and AR COMP with my Elisio chassis with Tubb bipod and rear squeeze bag.

Yup,. OR,. the 6XC !
Both are,.. better choices !

Well you can get it now in Alpha brass which seems to be pretty good however I agree I won’t build a rifle to compete with I can’t get Lapua brass for . Back in the day seemed the 47’s were much harder to tune than 6br’s and it’s wildcats but I have seen some really well tuned nice shooting 6.5 and 6.47 Lapua’s

I’ve had 5 of the 47’s. Never had an issue on tuning. I believe there were some reamer issues with one of the reamer producers who spec’d a so called “no-turn” reamer that required neck turning. I know of several people who had difficulty due to that.

Never had a problem with tune on my 6x47. I can run it just as fast with
less barrel wear. The 6 Creed seemed to burn barrels faster than the 6x47

I’m just under that actually with my 6 creed I’m 3158 with 115 Burgers. I’ve often thought about a 6/47 I’ve had 6xc’s but done most of my competition shooting with 6brx and Dasher and one 6brdx .

I think it's as others have said, the reamer has to be just right.
The other speeds that I measured that day were, 3173 and 3175.
Usually in the 3145-3155 range. It still shot really small.
This is with Roy's 103g

I have a few .243 caliber rifles - 6x47, 6BR, Dasher, and a 6 creed and lot of them shoot small but my best shooting rifle is a 6x47 built by Jon Beanland. That rifle has been a joy and I never had any tuning issues with it at all. That being said I like a lot of the cartridges being mentioned, there isn’t any bad ones in my book. Just as an important, maybe even more important as what cartridge is who builds it.

Do more research on the 6GT. The 6 x 47 was the parent case originally. I really like mine and I run Alpha brass which seems every bit as good as the Lapua brass I run in my 6.5 x 47 Lapua. The 6GT fills the sweet spot between a Dasher and the 6 x 47.

Pick the one with the best and most available brass in NZ.

For what it's worth, Lapua 6x47 brass lasts a very long time. If it was me, I would build a 6BR

I am looking at this myself right. I have wanted to build a 6BR for a while one an action I already own. Everyone tells me over and over again that getting the 6BR to feed and extract even from a blind magazine in a short action factory action is problematic. So the BR makes very little sense if I have to order a custom action, only 2 gunsmiths on the earth can make it feed and extract right or I need to go to a detachable AICS mage or what ever.

Some cartridges are so specilized that they are about like the most imbreed of European Nobility like the Habsburg House! They are fantastic for the one thing they are meant to do but once outside of that all of their "quirks" start to become apparent especialy when you live with them day in and day out.

When getting into the weeds on some of these mostly competition breed cartridges one really has to talk about feeding, extraction, and the very very specific actions, magazines, and issues some of them are well known for in their very specific disiplines!

Maybe it is because I am older and have lived through mulitple brass, lead, powder and primer shortages. Just look at historicly how diffacult it has been off and on for decades to get any 284 Win brass not talking about match grade brass I am talking about any brass at all! If you start talking about 6.5-284 than it gets even more hit and miss!

I think everyones level of risk aversian and everyone expectations for feeding and extracting varies wildly when talking about 6mm bullet choices!

I like being able to use off the shelf actions, bolt faces, and easily attainable brass! The last 4 years has not been very fun for me! Having to go to auction sights to get brass and primers and pay 10X as much for them is also not m idea of brotherly love and susatainable hobby!

I had a mentor from NZ who is now dead but NZ is not the same place it was 20 years ago. I would think long and hard on this and I would consider purchasing atleast 300 pieces of brass up front if your serious. Depending on which way you go you might get 3x reloadings or 11x reloading. Guranteed to be able to wear out a barrel or two! Your one pandemic away from not having a hobby or not being able to get supplies for you hobby!

If speed matters (that you can't notice without a chronograph) trust me, 100 fps is not relevant at 600 yards, where the 6x47 shines! Both leave a little to be desired at 1000. Less than great brass doesn't bother you, and barrel life isn't a concerns,,,, by all means go with the CR for the cheap brass, ok accuracy, and lower life.

But if relavent speed, extreme accuracy, easier tuning, and better barrel life matter, only one choice, 6x47L! It's Lapuas prized 6.5x47L brass that cannot be equaled, fact! The ease at which the 6x47L is formed from it, and the ease of tuning, with more loads that will make it more competitive at 600 and 100 yards, the 6x47L wins hands down!

Ask yourself "why don't we see folks using the cr in any form for extreme BR group competition,,, all I can say,, and yes, I actualy do have experience with both!

My 6 creedmoor is very accurate with Lapua brass but yes I agree if your competing use what’s winning and in br you don’t see creedmoors

6.5 x 47 Lapua because of heavier bullet choice if desired!

The cases are very similar. My other rifle is a 6.5 x 47. The 6 GT has plenty of history. Second to 6 Dasher in PRS popularity.
