Great rifle and action is smooth! I have one in 25-06 and also one that I custom barreled and stocked in 6mmbr. Love em both.
Some one can correct me if I am wrong, but I would guess it is a 1 in 10 twist. So I would look into larger bullets especially for longer shots. My self I would not load smaller than a 168 and I would prefer a 180, 190 or a 210. For shots out to 500 yrds I would load a 190 or 210 Berger.
