Berger 184 hybrid

[highdrum]

I used them to form brass in my 7-300prc. Tried everything from 20k to 100k off the lands behind 74gr H1000. The only thing that shot sub moa 5 shot groups was 70k off lands. I also have 190s and 195s to try. Have a lot of freebore in this chamber. 100k off lands has bearing surface even with nk shoulder junction.
