Rl 19 to h1000 charge question.

[light rain]

Guys, I have a 30 hart. Which is. 300 wby improved, the recommended load is 81 grains of rl19 and 180 nosler bt.

Well I want to shoot the Berger 215 hybrid and h1000

No one yet has given me an idea on where to start. Do you think 80 grains and work to 83?

I played with my quickload a little on this for you . quickload does not have a 30 hart , or a 300 wby imp so take this info with a grain of salt . I'd say you would be safe starting in the 79.0 - 80.0 grain and working up towards the 83 grain area .

a standard 300 wby with your 180 B-Tip and 81.0 grains of RL19 gives 70308 PSI chamber pressure .

to get to this same pressure , using a Berger # 30423 you need 83.5 grains of H1000 .
