Just wondering where to start with bullets and powder.

I have some stock of Berger 168 VLD (quite many of these), Berger 175 VLD, Hornaday in 208 Amax and 150 SST. Which one should I start with? I have more, but these are the only Hunting projectiles I have.

We have places where a 400-500 yds shot is possible.

Also the powders I have are R17, H4831SC, N160. The local store also has IMR7828 SSC

Obviously, I am not limited to these, but would rather start with what I have.

Thanks in advance.

Mike
