+10 on PT&G. Ask for Dave Kitt, and he will walk you through their Uni-throater tool which comes with a T-handle, sleeve stop, and lock nuts to set the depth. I just used one to lengthen the throat on a 6.5 Grendel which are noted for short throats anyway. It was VERY EASY to use. You need to make a dummy round with the longest bullet that you think you will shoot, and set at the seating depth that you prefer. A Hornady/Stony Point tool is a good investment to set the seating depth in relation to the leade/throat.
As German said, the 175 to 190 gr. bullets are the way to go for long range shooting, and it will probably shoot the 155's well also.
Good shooting.
