I don't think a 1:12 twist and the general idea of long range (over 600 yards) go together. You are going to be limited to lighter/shorter bullets that won't maintain velocity for long range accuracy. If your idea of long range is 300 yards you are probably going to be ok. You may get by with the 62 gr. bullets but the 75 gr. will be a no-go.

Here is an informative article Craig Boddington wrote with a table illustrating various bullet weights and twist rates.
