Too bad most "accuracy" determinations are flawed by us humans' inability to hold, fire and move in recoil exactly the same for each shot. Some are more repeatable than others, but such is life.

Regarding the comment:
What effects the accuracy of the bullet most is the shape.
I strongly disagree. Bullet balance is far more important than shape. The more unbalanced they are, the more they'll jump off the muzzle axis as they exit and take a more irregular spiraled path downrange as well as having a greater drag going through the air causing more vertical shot stringing as range increases. Doesn't matter how streamlined or blunt nosed they are; if all have exactly the same shape and weight and are perfectly balanced and leave at the same muzzle velocity in a stable atmosphere, they'll all go in the same hole down range because they all have the same ballistic coefficient for each one. The only difference is the streamlined ones will have less of a trajectory arc to the target than the blunt ones.

Nowadays, there's no significant difference between the best boattail and flat based bullets. Benchresters used to prefer flat based ones for short ranges but seems the boattail ones have finally equalled and often bettered them. It takes a rifle and shooter capable of consistant sub 2/10ths MOA at short range to tell the difference.
