Primers for SRP Lapua 6.5 Creedmoor

[Drvred]

I just bought some Lapua brass. I have several hundred BR4s I intend to use.
I also use them for my Valkyrie.
I just found 1000 CCI 400s in a drawer.
Are the cups too thin to use for a moderate 6.5 load (43.4 RL 16 behind 130 Berger OTMs) or will I get pierced primers?

Thanks

I say no, CCI 450's should not crater or be pierced, if so, look at headspace. BR4's really should not crater either. From personal experience, I am going to go out on a limb and say that you will get a more uniform burn with the BR4 using RL 16.

He said 400

Dont use the 400s.

Here is a pic from my cousin where he tested 30 of the 400s in a dasher

I wrote that terribly.
I was trying to ask if the 400s would pierce, or crater, sorry.

Don’t do it, like spife showed above.

Another issue many miss when switching to 65CM Lapua brass is make sure you have a set of dies with the small decap pin in your sizing die or atleast a universal decap die with the small pin.

Also, I have loaded enough and fireformed my share of cases, there is some headspace issues playing in that flat primer case.

I've use Federal 205's in my Lapua brass with no issues. But, I'm also running 130's at 42.5gr of R16 or 140's at 41gr of H4350. I dont hotrod my shit.

What kind of velocities are you getting with that load?
43.4 in Hornady cases is getting 2918 in my Savage 24"
Funny thing is, last weekend I was getting that with 88°,95% humidity.
That was the same velocity I was getting last November @ 58°

In lapua brass I run 42.3 of R16 and get right around 2812, SD 9, ES 22 @54 degrees Fahrenheit out of my Tikka T3x Taca1 24" factory rig. It duplicates the Berger 130g factory load which shot 2810 at 53 degrees F.

Thanks, I know I will have to rework my load for Lapua, I plan a ladder test for tomorrow.
