where to start?

[white121]

I am having a 243ai built so I need to fire form brass and then find that perfect load. My question is should I start with lapua brass off the get go or should I buy a 100 pack of bulk ammo fire form with them and work up my load, when I find that load that I am looking for then duplicate it with the lapua brass.

Stay with the Lapua. If you watch your shoulder bump, it will last you a very long time.
