Thread: 300 WSM subsonic any advice please....is it worth it????

Hi fellas
I'm thinking about having a play with Subs for my 300wsm sadly i am still looking at 80m to 100m+ shots as im shooting in mostly open country and its harder to get up close. so I am looking for any advice on....

what's the best weight and type of projectile?
what powder should i use and what amount is a good starting point?
bullet drop at this type of range so i know were to start?
and most importantly is it worth all the effort and cost using this calibre?

Any help and comments will be welcomed.....
Cheers
