Primer question

[josebd]

I know the CCI 400 primers have thinner cups than the CCI 450s, I was just wondering if anybody has used the CCI 400s with the 6GT and the 6BR?

A while back I Did a load development with the 400s in my two guns. I had been using 450s. I think I ask someone here about em. Yeah, one guy on here had told me he had to switch to 400s for a match. He ended up winning.
One 6br liked them.
The one that liked them was a a hot load. Or at the higher end in terms of what I thought was max. The other gun shot heavier bullets, I couldn't really see a difference in that gun.
I had used 400s lot more when I first started shooting 6br. 70 grainers.
They work fine
