Thanks for your comments.
BILL, I cant really help you with the variations of the Brno's but maybe you could ask the question as a seperate post ?.

TOPHET1, I think 7x57 is another great choice.I had one years ago but built it with a 24 inch #5 profile barrel that took away from what 7mm's are all about (punching above their wieght). If I had of made it smaller and handier I would still have it. Tony certanly gets through his work !.

OZHUNTER,I was thinking along the same lines as you. 450 grain Woodleigh RN & solid @ 2150-2200 ? What do you think ?.
