New 6.5

[Cajun Blake]

So question if I have a.25-06 that I want to use as a donor action for a build? Can I use for a 6.5 Creedmore? Sorry for my ignorance just trying to understand a little better.

If I were in your shoes, I'd use the LA and shoot it as a "single shot" or find a SA and go repeater

ANother option with your LA ... the 260 with 140/142's seated long and/or the 6.5x55 Swede


good read ... http://forum.accurateshooter.com/thr...dmoor.3797070/

Those are good choices for long action... second option for me is I also have .204 I hardly ever shoot it anymore and wanting to do a build of something in the 6.5 range? Can I use that action or is it to short? Sorry to hijack last question

Love these threads have learned a ton from you guys Thanks

No idea if it needs a long action.

I remember recently reading about someone building a 6.5x300WSM....
I've got a 300WSM......

That's me, and I'm running it in a Winchester model 70 "WSM length" action. Outside dimensions are the same as a short action, but the ejection port is longer I think. Will the round work in a short action? Yes. Is it ideal? Not really. I'm using Alpha Industries mags, based on the AICS pattern, so they allow me to run out to 2.970", which still puts the base of the 140gr VLD bullet below the neck shoulder junction slightly. It still works amazingly though, I'm running over 3200fps with 140gr VLDH's and they are murderous on game.

To the OP: Your intended use will dictate what you should build, but they end up being the same. The x47 never really caught my attention personally, but that is just me. Since you are running a SA, and I'm assuming standard bolt face, you've got the x47, the Creedmoor, the 260 and the x284 (although not ideal). So leaving the x284 out, the other three are essentially a set of triplets. Lapua makes brass for all three, so no benefit there. I've never seen x47 on a shelf anywhere, and only seen 260 a few times, but Creedmoor is growing in popularity and can be bought many places. Yes, I'm sure you reload, so do I, but there are times when I just want to go to the range and I don't have time to load, so I grab my 308 and a box of Hornady and go shoot. That's a point for the Creedmoor. Now, I'm a speed freak, hence my wildcat based on a WSM case, so one probably go with the 260, but I'd do an AI chamber to pick up a few fps, or one go with the x284 and just eat the preformance loss from seating the bullets too deep.

For a long action, standard bolt face, I've been considering a 6.5-06 AI, but with my current experience with my 6.5 WSM, and finding brass, having to neck turn, etc, I may go with the x284 version and be done with it. Sure do like that WSM case though.

Looking at having a 7mm LRM put together soon as well, just haven't decided the exact route I want to take.

I'm in the gathering stages of a 6.5 build and like you I have considered the 6.5x47 but keep looking back at the creedmoor. I also have a 6.5-284. My build will be off of a Rem 700 and benchmark 1:8 5R barrel. CB makes a good point with those targets. I'll most likely go with 6.5x47.

I'm about to start a new build on a short action 6.5. I had settled on a 6.5x47 Lapua but I'm having second thoughts. Since I made that decision I began gathering my parts. I already have my barrel and action so I'm not going to a long action or anything other than a variation slinging a 6.5 pill.

Talk me into our out of the 6.5x47.....but if you want to talk me out of it give me a better alternative and your reasoning.

Thanks!

Either are great rounds but my hands on experience with the 6.5x47 is better.
If you reload go with 6.5x47. If you buy factory rounds then Creedmoor. Don't know why but it seems I shot little bit more accurate with the 47. Side note:130gr VLD is all I've shot out of it. It's a fun round and I've seen deer drop in track out to 600yds no issues. The 47 is just a blast to shoot!! I own a 6.5x284 and my next build will most likely be the 47 with a 18.5" barrel with suppressor sitting on McMillian Gamescout and Stiller action and Jewell Trigger. 2 of my buddies own this build and they love it.

You have to match up the bolt face of your donor action to the cartridge you select. Your .204 would have a bolt face of .384" You will likely need to build on an action with a .470" bolt face for the .308 family of cartridges that are used with most 6.5's

You've gotten great advice and input so far. Here's my summary of the advice:

Reload? Yes. 6.5x47 Lapua.
Reload? No. 6.5 Creedmoor.

Problem solved!

I am somewhat biased but out of the two, I would say the Creed. Lapua is making Creedmoor brass early next year and will edge out anything that the 6.5x47 can offer.
If you reload and want to do a magnum bolt face, go with the 6.5 saum.

What do you mean by this? Lapua makes brass as well in the 6.5x47, so no advantage there. What data are you using to make this conclusion?

The Creed has more horsepower via longer case, just as long of a neck, same 30 shoulder angle, and still fits in standard length magazine. People were able to offset the smaller boiler room of the 6.5x47 by pushing to higher pressure by using superior Lapua brass with small rifle primers. Given same pressure, the 6.5 Creed in a Lapua case will blow the 6.5x47 out of the water.

Will the lapua brass for the Creedmoor also use small primers? I'm not sure how much difference primer size really makes as far as pressure limits are concerned, since they are supported by the bolt face everywhere except the firing pin hole. I do have a ton of small rifle primers though, so it might be worth it for me to build a rifle that uses lapua brass. I've been considering a lighter weight hunter in a high preformance caliber that won't beat me to death with recoil. I love my WSM, but I intentionally made it heavy to mitigate recoil, and while that worked great, it's a bear to carry around much.

Yes, the new Lapua Creedmoor brass will have the small primer just like the 6.5x47 brass. This will let the Creedmoor guys run the same pressures the Lapua guys have been running, and at that point you will begin to see the case volume difference in the two cartridges.

[ltsheets]

Very happy to hear that Lapua will be making CM brass soon. I have a super light rifle I was going to rebarrel into a 6.5 variety to reduce recoil slightly when the time comes and Lapua CM brass will be hard to beat.

C'mon man ... "Blow the 6.5x47 out of the water" ? .... yeah OK . Perhaps a minimal gain of up to 100 fps at best.

First of all, there's roughly 5 grs (10%) more case capacity for the CM ( 52 grs ) over the 47L ( 47 grs). Common physics would tell you more case capacity = more velocity. However; increased velocity does not always equal increased accuracy.

All barrels and cartridges have an "accuracy node" where they shoot best. The 6.5x47L seems to like the 140 gr bullets being pushed at 2750-2800 fps. This is clearly evident by the chart below.

Given the same weight bullet, and reported muzzle velocities by PRS shooters, the CM only yields a 2% increase average in "feet per second" for optimum long range accuracy . My 6.5x47L shoots a 1-hole group with 40.0 grs H-4350 and a Berger 140 gr Hybrid at 2780 fps. I would expect the 6.5CM accuracy node to be around 2817 fps with several more grains of powder.

Of course this is all relative based on powder and charge weight. The 6.5x47Lapua is not only proven by the number of World Records it owns, but also by it's efficiency and inherent accuracy.

In summary, will the 6.5CM with Lapua brass blow the 6.5x47L out of the water .. NOPE !!! Perhaps just a little bit more velocity that a deer, hog, rock chuck, or plate of steel will never know the difference. Nothing wrong with a quality built CM , as this disputation could easily be answered by "What's your favorite flavor" ?

my Manners stock is currently being repainted as I'll post up pics of my rifle when I get it back

The larger primer pocket is a larger hole in the case with not as much material in the cross section. Although the bolt supports the case head, there is still a bulge outward that creates loose primer pockets with excessive pressure. Small primer greatly reduces this. I am comsidering a 6 Creed for next build since I already have a 6.5 saum
