CCI 450 instead BR4 on 6,5x47 Lapua

[Bora72]

Hi to all!

Here I've found 1k of 450 at less of the half price of BR4.
So I ask to this forum if the 450 is usable on this caliber whitout trouble.

On my reading of "anglo" forum's I've found that cci 450 are preferred to BR4, also on the shooting competitions.
On EU BR4 is preferred to other primer on x47 Lapua.

Now I use Fiocchi SRM but I'm a novice....

Bullets are Berger 140gn 26414, Scenar 139gn.
Powders that I use is N140, N150 and RS50.

Thanks for replyes

They are usable. BUT, when swapping over to the mag primers backing off the load and testing back up is the best and safest approach.

Hello, off course when change the components is necessary make test for best results.

But I prefixed my self that I use only mag primers on all my loads.

Thanks

@Bora72
Along with the excellent posts above, I’ve found that in my receiver these two primers are quite close to one another in performance. The very best way I’ve learned to test them is side by side in a charge ladder format judging not only overall grouping but identifying just how the load comes in and out of tune. The node may move slightly up or down in charge rate or may remain the same. In my case the overall was better and was less course coming into tune with the one I choose yet the ideal charge weigh is basically the same.

Hope this helps you.

Being a 450 Fan from .308 SP Brass to my 6Norma Dasher and a lot of others I know, they be outstanding.

I ran a test in my 6.5 CM with both of these primers.

BR4 primers had higher velocity and higher SD.

CCI450 were slower velocity, lower SD and had better accuracy.

BUT........that could all change on the next lot tested.

The CCI 450's are not going to be a problem at all.
Lot's of shooters use them.
Those two primers are very close in performance.
You just have to test them both to see which one works better for your load.

CCI 450s are the small rifle primer of choice of many. I would buy them, fine tune my load and shoot with confidence.

Hello JFrank!
Thanks for your post and yours suggestion.

Yes, I keep in my mind to make this test whit BR4, 450, Fiocchi SRM and Winchester WSR.
Same load, same bullet, same measures for the cartridge.

Thanks!

Hello 6.5 forever!
Your test is against the trend, but is your test and is possible taht on the other test session the results will be very opposite...
Test are test...

Hello Ranger188!
Thanks for the comment, yes I make some test!

Hello JLT!
I will definitely follow your advice too!

 

[JLR]

I've ran CCI450s in all my 6.5x47 and 6x47 since 2008. I've never actually tried BR4s, since the 450s gave such good results.

I've shot 10's of thousands of 450's in my 6.5x47L for the last 15yr. Accuracy and low single digit SD's don't lie.
