Another primer question for 6BR....

[Dave T]

Why are CCI 450 small rifle primers thought so highly of by a lot of 6BR owners? I understand the cups are harder and it's a magnum primer, but why not CCI BR-4's, aren't the cups the same and does the 6BR need a magnum primer? Or is there another reason why so many like the 450's? Or am I missing this completely?
Thanks,
Dave T

Might depend upon which circles you run in. Most of the fellows I shoot with and against use Federals. Surprising number use winchester. And some use 7 1/2. As accurate as the 6br is for the most part, a fair number of shooters can't out shoot the difference a primer makes in them. Just my experience. WD

I use Wolf SR Mag primers with great success. Lower ES's than other brands and no blanking.

Note" Wolf SR primers that I have used are VERY soft, more like pistol primers than rifle primers. These were purchased a few years ago and hopefully Wolf/Tula has corrected this.

I use the CC1 BRs, Federal golds only in the PPC and have played with the magnum primers in the improved BR cases (Dasher, BRX, etc...)

I believe your original question was regarding the CCI-400, not the CCI-450. I had no response since nobody I know uses the 400 in a 6BR.

Yes Dave, I changed my original post, I meant CCI 450 primers and I also experienced high velocity spreads with Federal 205M's and I want to get that better.

I was thinking of using the CCI450 primer with 105 Berger Hybrids but have Wolf Small Rifle 223 primers (hard cup) that I could also use. Has anybody had any experience with the Wolf 223 primer in 6br?

I usually shoot a 308 with 155.5 Bergers and have had great success with the Wolf Large Rifle primers.

One of the fellows I shoot against uses them and he swears by em. I think(?) he shoots 90 or 95gr bullets though. He's consistenly tough to beat with that rifle. WD

In my opinion it depends on the bullet weight and distance.
I use F205M in my 14 twist at 100-300yds because thats what I've found to be the most accurate.

Heavy bullets at longer distances is a whole nuther story.
The 6BR shoots very well in both worlds. We should'nt forget that.

I have two 6brs in 1-14, a Lilja and an Atkinson & the Fed205gms produce better results than CCI-400, 450, BR4, Rem 7 1/2s.

Sorry, I wasn't specific enough in my previous post.... Yes, there's a fellow that I shoot competition with that uses them in his 6br... but I think(??) he shoots either 90 or 95gr bullets. He's always tough so the primers aren't letting him down any and he swears by them in the 6br. WD

I started out with Varget and the CCI BR primers. Read in several places that the CCI 450's would shoot better with Varget and heavy bullets. I have found this to be correct. The 450's have a smaller ES and they shoot smaller groups - with Varget. I have not tried them both with any other powders. I shoot a factory Savage with an 8 twist barrel and 107 Sierra's. I do all of my 6BR shooting beyond 300 yards.

I'm by no means an authority but I've had great success with the Wolf 223 primer. Nothing fancy, 105g bullet, varget, lapua; occasional testing @ 100 yards but 95% fired @ 600-1000. Single digit SD, very low ES. Hope this helps.

Dave,

To answer your question, there are several reasons for the CCI450 in the 6BR,

- Improved accuracy, lower ESs a,nd SDs (for some).
- Increased speeds over CCI BR4 while enjoying same high pressure containment (for most).
- Shooters like to copy what they read without performing own tests (many).

Now the skinny, Fed 205M and CCI BR4, have, and continue to be, an excellent choice for ultimate accuracy, while printing low SDs and ESs, for most.

There has been a contingency of shooters whose rifles have shown a preference for the CCI450. Not strange, specially when understanding the complexity of what seems to be a rather simple cartridge. And it shows when you consider its brethren, like the BRX, BR Imp, Dasher, etc, etc, where the common denominator is "higher speed" while maintaining the 6BR's inherent accuracy. A CCI450 may help achieve a higher speed threshold where another accuracy node may exist. And hurray for it.

Another great primer was the original Russian SRM (first couple of incoming lots). It enjoyed a hard cup, able to withstand high pressures, while having a low ignition, and some of the lowest and most consistent ESs and SDs I've seen. Some didn't like it because of what was believed to be lower obtained speeds. I loved it for it, as I have never belonged to the school where a primer should be part of the pressure volume equation. That's what we have powder for, add or retract, and the 6BR enjoys good capacity to allow for it.

Last but not least, it is true I have witnessed a few rifles that shot better with the CCI450. It is also true I have shown them the same accuracy/speed, or better, with a different formula, and not using the CCI450. My personal 105 Gr. 6BR ammo, and most of which I make for others average between 2,950 and 3,000 fps, without the CCI450. Mind you, chamber design has a lot to do with it, as there are some that will not allow these speeds and pressures.

Either way, find what works better for you, and stick to it.

Have you seen what BR-4 primers are going for these days?

I would have to think that is something of a factor. I'm not sure why CCI thinks the BR-4s are worth so much more money than any other primer, but if the results are the same with others, why pay more?

I for one, haven't been able to find much truly attributable to primer alone. If you switch primer you may have to change powder or powder charge, but you can usually find about the same results with any other decent primer out there.

So in short, I would think that the 450s were probably discovered almost by accident as a good primer and then became pretty popular and because they are the most closely related cousin to the br-4s at a much better price.

I ran a test of my worked up load with each of the primers mentioned, except wolf, and the test results told me what to use. the groups speak for themselves. try it.
