I have a nice custom 9.3x62 built on a Pre 64 M70 action and a 24" #3 Pacnor barrel. Very accurate with 250 AB's and 286 gr PT. I've been shooting one of Veral Smith's LBT cast boolits using one of Veral's molds he made for me. Due to the short throat, Veral's mold is throws 174 gr boolits. After talking to Veral at length, he suggested I ream the throat longer to get up to the 250 gr weight I want. He's going to make the mold. I just need to ream the throat. I've now got a PTG 9.3mm Throating Reamer. A little apprehensive.

Any sage words of advice?
