ratsnakeboogy said:Yep, Barnes says Ramshot Hunter is the most accurate in their test barrel. I have read that they also reccommend seating the bullet .05" of the lands to start. Most say good accuracy comes at .03"-.08" off, depending on the rifle. I was under the impression that just barely kissing the lands was what you wanted in reloading, but they say different. I'm new at reloading, but I bought some 85TSX for my sons .243 as well.

Because TSX Bullets are all-copper, they have different pressure characteristics compared to conventional jacketed bullets. In our lab, we have experienced best pressures and accuracy when TSX Bullets are seated .030″ � .070″ off the lands (the grooves or rifling in a barrel.) The majority of the time, we�ve seen optimum accuracy when bullets are seated .050″ off the lands, so start there. Then move backward or forward in .005″ � .010″ increments to find the �sweet spot� for your particular rifle.
