Anyone have any positive or negative results with the Grand Slam? Seems that Speer is pricing this as a premium bullet, about 5 bucks a box more than a box of Accubonds. Both .308 200grn. From what I read the Grand Slam is not a bonded bullet. Just wondering why Speer wants so much for a non bonded design. What have yall seen as far as accuracy with it? How well does it stay together?
