Lekker. That sounds promising.

Do you have spare case capacity if you need to up the charge?

Too much space. I've got 3 grains of dacron holding the powder down at the moment.

Lapua brass has the smaller capacity compared to TZZ.

With the Lapua, the space between just below the body shoulder junction and case shoulder junction is empty.

With TZZ, the space is 3 or 4 mm below the case shoulder junction to the neck shoulder junction.

Case capacity difference is 8 grains of water.

I've tried N570, US869, 20N and 24N - none of them give proper case fill over a CCI 35. And with the CCI 35 it doesn't matter, even if the powder is half an inch from the primer, it'll still ignite.

Watched a video by Halfmilesniper. His 6,5PRC gained about 50fps when he changed from CCI200 to WLR primers.
