[QUOTE="bruce_ventura, post: 1073249, member: 34084"] You can check base alignment yourself. Install the bases and then place a 12" steel ruler against the right sides of the bases, with the front of the ruler sticking out toward the muzzle as far as it will go. Look down at the barrel and measure the offset between the barrel and the ruler. Then switch the ruler to the left side of the bases and repeat. It the measurements are the same, the barrel is centered. If not, then what is the numerical difference between the two measurements, and how far from the center of the bases did you measure the offset? Calculate that angle. It could also be barrel vibration throwing the shots off boresight. You could try different ammo. [/QUOTE]
