Does anyone have any load data for the new Berger 230 Gr 308 Cal Hybrid bullet for use with a Remington 300 Ultra Mag. I have Remington cases and would prefer to use Hodgden Retumbo, H1000 I live in Australia and that powder is readily available here. The rifle has a 26" barrel with a 1 in 10 twist. Can anyone also tell me the BC etc for that bullet.
