Need 6mm advice

[Sniper338]

My opinion: 6XC or 6X47 Lapua

I just had a 6XC barrel made, and its tickles me to death shooting it..

I hate a 243, I'll never own one again, I've had way too many problems with the round in several different rifles, thats why I went to the 6XC instead for my 6mm cartridge.

6BR and 6Dasher wont feed in a repeater reliably, but are dang good rounds too.

The 6SLR is still too new and undeveloped I THINK, could be good, or it could burn barrels quick, I havent heard results with it from anyone thats ran it hard yet. Everyone that talks about it is probably not even half way through their barrel life still. So far it's still a fad I think, I havent seen it prooven yet. If a round is prooven itself you will see it being used for competition stuff..

My Marlin X7 6 Dasher feeds just fine with no reworking of anything. Maybe I just got lucky, but I have been using it for 3 years now and have no issues. It's not a build, but a .243 Tikka would imo do your job. Barlow

This is a great blog and I appreciate all donating their time, knowledge, and experience with guidance for a new member. A few members provided excellent technical detail that added depth to the discussion. I've narrowed my choices down to 6x47L and 6XC, with the 6XC looking better every day. I'm still working through some issues but when I decide on the build or rifle I'll share with the blog. I'll continue to monitor the blog but just wanted the opportunity to thank all.

6mm creedmoor, does everything the Xc does without the hassle. 6 X 47 L a very close 2nd. You can push the creedmoor a little faster and if you lose a piece of brass you dont cry. Jon

I've heard good things about the 6x47. However, same people say it's hard to turn and keep in tune.

I originally was going to build a 6xc but at the time brass was almost impossible to find.

The 6br and 6 dasher shoot lights out. Feeding can be tricky but doable so I've heard.

I ended up with a 6SLR. I'm approaching 800 rounds down it. I've been happy with the accuracy, I've found 3 loads that shoot under a 1/4". Two with H4831 and 1 with H1000. My rifle was built for tactical competition and has a 24" med Palma barrel. I've shot 4-30 round 600y fclass comps with it. My scores have been running mid to upper 280's. Not great but I'm a beginner. I shoot it hard in practice and have had it hot several time and haven't noticed any change in accuracy. My only disappointment has been with the MV. I've only been able to get it up to 2970 with the 105 hybrids. Ordered some RL26 to see how it does. The brass is easy to find and form. Just size and load. It has a wide range of workable powders so even in the hard times I should be able to find something tha will work. All in all I would say it would work very well for your needs.

The 6creedmoor could be another option. I think it has a smaller useable powder selection, pretty much H4350, which is hard to find.

Hope my info helps

Hey had2b, I'd appreciate you keeping us posted. I'm kind of stuck right where you are. I love Lapua brass and was just about set on the 6x47L. Then I kept seeing posters say it was hard to get to shoot. The thing I love about my 6BR was it was stupid simple to get to shoot. Wonder how the 6XC is in that regard?

well this is how I feel about it. There is no hassle to the 6XC..It has been stated the only other cartridge as easy to load for is the 308 win. I have shot three different powders in my and all have shot well. it just shoots with out too much tuning and the velocity's I have got from a 26" barrel has been more than what most say they get from a 243 or 6SLR . I have had no problem getting a 105 VLD to 3,150 FPS and the Norma Brass holds up . tight primer pockets.

I have a 6.5 creedmoore. I would assume the 6mm creedmoore is using hornady brass. I have 150 brand new Hornady 6.5 creedmore cases. If you drive to my house right now I would give them to you. The Brass is JUNK! JUNK! I have called hornady and they wont even talk to me. yes loose them, leave em lay..

So 6x47L or 6XC.. The Norma brass is as good as the Lapua IMO..Maybe not as good as the old cardboard box 6BR brass.

I have also heard the 6x47L can be a little fussy...But shoot great other then that.

As stated you buy the Norma brass for the 6XC and be Happy or Buy the Lapua brass for the 6x47L. But you can run a 22-250 case in the 6XC die and fire form..If you go to the home page on this site you can read about the 6XC and the other cartridges.. You can go to 6mmAR.com and read about quite a few cartridges. do some research on your own.

Yea I don't understand what you could mean by with out the hassle ? there is no hassle. You buy good quality brass and go..I tell you now if you are shooting Hornady brass you have no idea what a quality brass case is. once you use Lapua brass it is hard to shoot anything else..well I feel the Norma 6XC brass is that quality.

HTSmith there has been some talk that the 6XC is a more inherently accurate cartridge than the 6BR..I say I really don't know about that. it's tough to beat the 6BR out to 500 600 yards IMO in the accuracy department. I have owned several 6BR's most of them heavy barreled single shot's.
All barrel's are different mine seems to like a little more powder than most.
those are one inch squares in the target. sized to fit the screen it looks big but you can cover them three shot with the back of the case.That is a #3 sporter barrel.

the 200 yard target was the first time I fired it at 200 yards. just working up a load. as it turned out up .5 grs of powder got rid of the vertical. Now understand this is a #3 sporter hunting rifle. not a heavy bench gun.
Yea it seems real easy to tune. the 200 yard 5 shot group is a outside measurement. so I figure it's just under 1/2 moa. and it does shoot better then that if I do my job.

Ford vs Chevy, I do agree I got alota love for Lapua brass

My 6mm Competition Match is still holding 4 and 5 shot groups like this with 4000 rounds down it. I just put it on paper. With what the OP is looking for, I would just go with a straight .243 and run H1000 in it with a 105.

Do it your own way. :-*

I was kicking around a 6mm back in January. I like performance and wanted a hot rod that would go if you wanted to step on it, but in short action.

So I did my own caliber. 330 yard point blank for varmint hunting and little more energy than an ,06 for deer hunting. One of my first 5 shot group's was a .67.

Pretty hard to beat so far. I can't wait to see what it will do when jamming and testing a couple more powders.

I considered the 6mmXC, 6X47 Lapua, 6mm AI, 6mm-.284, and finally the 6mm-06 for a new 6mm.

After a trip to the range running drop tests out to 500 meters I determined that there was not that much difference between my existing 6mm AI (50 grains of H1000 and 105 Amax) and .243 Win (43 grains of 4000 MR and 105 Amax).

I went for the old slopy shouldered short necked .243.

All I intend to do with it is shoot varmints and steel.

The Alpha Creedmoor brass brings that case into the 6xc 6x47L league. I would choose among those three for all the reasons above. I don’t think the 6x47L is finicky, mine sure wasn’t, the neck was a bit too tight to be no turn though. Over the next 5-10 years, I think there will be more Creedmoor factory ammo available than anything else. That 6 Creedmoor case could get really popular.

 

[jr600yd]

6XC Lapua, Peterson, Alpha, Norma brass and be done with it.

 

[riflewoman]

For all you want to do either a 6/250 or a 6mm Creedmoor. The 6/250 is a simple neck up operation on 22-250 brass and the 6 Creedmoor is either a neckdown of 6.5 or buy new. Both can be fed from magazines. Install a 8 twist barrel for the longer target bullets.

This. Lapua brass in 6mm creedmoor has become available and decent, inexpensive loaded ammo from Hornady is also available. With heavy bullets, it fits and feeds well from short action mags. No brainer.

I've got three 6 Creeds now, wouldn't hesitate building another one if I needed another rifle. Brass selection is outstanding, btw. My latest addition here.

I wonder if he ever figured out what he wanted. Been a few days. Should have decided by now.

Look at the 6X47 L. The brass is from the 6.5X47 L, I am going to build one. Look at the Berger loading manual. I like the 30* shoulder and great brass by Lapua. The SLR is a larger case and has a longer neck than the 243.

I agree also on the 6x47L. But maybe give the 6mm Creedmoor a look too. Many Pros and Cons I'm sure to come. But two things stand out for me, #1 is that Lapua now makes 6mm Creedmoor SRP brass (no more necking down 6.5). #2 is IF you had to buy Loaded ammo you would have more choices to choose from with the 6mm Creedmoor. Neither of these two will effect you because you reload, so I don't think that you could go wrong with either one. So my vote is the necked down 6x47L. Good Luck.

 

[L W P]

if you are shooting Hornady brass you have no idea what a quality brass case is. once you use Lapua brass it is hard to shoot anything else..
