I know i have posted and asked question about brass weight but this brass weight is up and down bad.What do you do when its this bad. 210.8 grains to 206.3 grains.Theres no other company making the brass that i know of.can you get good groups out of bad brass such as this?

Skeeter, I'm no expert but I have spent a fair amount of time researching load data and even designing my own wildcats for competition. The first two questions you need an answer to before deciding on chambering for a cartridge are

1. Can I get Lapua or Norma brass for it?
2. What match bullets are available in this caliber?

If you don't have a real good answer to both those questions then your cartridge will probably be a headache to compete with.

WSSM cases will take off with 1k shooters as soon as someone makes decent brass. Winchester, Federal, Remington just don't get it done, unfortunately.
