Full Sierra loads tables are now available online at:

[AckleymanII]

I have both of these cases.

Recently found a load in a 24" Brux 8T, in the 6.5 creed.

130g Nosler accubond
41.0g of win 760
cci 250
Hornady brass
3130 fps
Shoots bug holes
41.8g was a working max load at 3180 fps, 41.0 shot a slightly tighter group
I have no issues with brass on the 41.0g load.

will this all be moot when the lapua small primer 6.5cm brass is released?

Hopefully just more of a good thing

 

[Spike A]

might be a stupid question but since you mentioned lapua small rifle primer pockets, will i need to change firing pins to be able to use the small rifle brass in my creedmoor?

No. If you have a somewhat sloppy firing pin fit in the bolt face and your are running higher pressure loads you may have a bit of cratering in the primer strike and if excessive, a bushed small pin would be best.

My choice was based on the availability of 6.5 Creedmoor factory ammo. I am too busy to reload right now, but wanted to get started shooting. I bought a Tikka CTR and the factory Hornady American Whitetail, 129 grain, and Prime 130 grain (Norma brass and match bullets) is really doing well. So far I am only shooting at 100 yards to chronograph velocities and while I am waiting on a spring to get my trigger pull down. Right now it is totally factory and has turned in some groups in the 0.5 to 0.4 range. The Prime is traveling at 2700 fps from my 20" barrel.

And your reasoning, KW, is the primary advantage of the 6.5 Creedmoor over the 6.5 x47. Save your Prime brass as it is very consistent in weight, thicker than the Hornady in several key areas, and lives long even with fairly warm loads.

Thanks rardoin. I kind of thought Norma brass might be OK. I ordered 240 rounds pre-election in case things went south. By the time I shoot that up, learn a little about shooting at distance, and start reloading I will have enough brass to shoot a while.

As a side note, does the Creedmoor cartridge stretch much?

 

[rardoin]

Very little growth to no growth with medium loads and 140gr pills.

Thanks for the kind praise, I think it is more the wind that pushes my bullets on target.

Haha! Yeah right! That's the humble nature of a true champion!

 

[smokinghole]

I was going to buy a 6.5 Creed savage prefit but the factory ammo argument doesn't do much for me. My 556 AR has seen one single cartridge of factory load. I have an AR in 6.5 BRX which I don't need to explain much more. I'm okay buying Lapua brass and loading. Criterion 6.5x 47L here I come.

I think a 6.4x47 has the bending world record at 1000 yds

 

[Grimstod]

One thing that i am learning as i progress as a handloader, is just how bad doughnuts can be for accuracy. Now the Creedmoor has a problem with these. Because 140gr bullets must be seated below the neck shoulder junction they are a real consern. I dont see the Creedmoor ever surpassing the 6.5x47 in accuracy. Maybe you could get good success with a long action that would allow longer OAL but then you might as well go 260ai.

So sorry Creedmoor but Hornady should have just started making 6.5x47 ammo instead of making a mistakecalled the creedmoor. Looks like the accurate cartridges will remain a nitch market. To bad.

So would you say the 130s are better suited for the creedmoore?

 

[Knotwild]

130's are working great in my 20" barrel Tikka. 2710 fps with Prime ammunition and groups 5 shots less than 0.500. I even had cheap Hornady Whitetail 129 grain throw me a 5 shot 0.369. It hates 120 grain Hornady Amax for some reason. So a $900 dollar factory gun works pretty good for me with factory ammunition. I can see the benefits of the 6.5x47, but they don't mean much to me or the type shooting I do, or am capable of. Plus, I probably don't shoot the number of rounds a lot of you shoot.

Huh???

6.5 Creedmoor handles 140+ just fine. I have beaucoup rounds, shot out one barrel, on the same set of 90 cases and no doughnuts. Grimstod, not sure where you are coming up with that issue. Could you elucidate? I know many other 6.5 Creedmoor shooters that would find that statement about doughnuts of interest. I, and others, have not had that issue yet.

It broke the heavy gun score and group for IBS. It is not the world record though. The world record heavy is 2.815 and 100 score shot at Williamsport with a 300 WSM. MATT

Doughnuts are very hard to detect. But when they form they ruin accuracy and throw shots. Often it will be almost imposable to know why a shot was off as a result of a doughnut. Basically use a seating depth that puts the end of the bullet beyond the neck shoulder junction. Suer you might get a nice three shot group every once in a while with doughnuts but try to do a grand aggregate and you will never succeed. Really its because the case is to long. If Hornady had just made the 6.5x47 as a factory option this would not even be a problem and then anyone could own a supper accurate cartridge. But alas it looks like the supper accurate cartridges will continue to be a specialty thing and not easily accessible to the average shooter.
